IASA Asks For Specific Wiring Specs

The announcement yesterday that AMR, parent of American Airlines would spend $1.7 billion to buy TWA and some assets of UAL's United Airlines, in deals to give it a quarter of the U.S. air travel market received a "cautionary" welcome from the International Aviation Safety Association (IASA).
IASA USA Vice-Chairman, Edward B Block, a world recognized aircraft wire and cable expert, speaking today urged the airlines to make public the type of aircraft wiring used in their fleets and specifically those wired with 'Kapton.' "With the scrutiny that aircraft wiring is subject to at the current time" said Block "any prudent airline would take steps to ascertain the type of aircraft wiring aboard their aircraft -- and particularly that of an airline it is buying."
Kapton is a wiring insulation trademarked by DuPont and the name commonly used by experts to describe any aromatic

 polymide wire. Studies have shown that that a crack exposing a Kapton wire's conductor can lead to a more severe reaction when it short-circuits than other types of wire. The continued use of Kapton insulated wire was banned by the US Navy in 1987 -- and is no longer used in military aircraft in the United States and Australia. In 1999, the entire space shuttle fleet was grounded due to problems experienced with wiring on its spacecraft. 
The wiring in question: Kapton.


The wiring in aging aircraft has been implicated in a number of high-profile accidents including the crash of Swissair flight 111 on September 2, 1998 and in the TWA 800 disaster on July 17, 1996.
In fact, the wiring in aging aircraft has been described as an "issue of national concern" by the Executive Office of the President in a May 10, 2000 memorandum that heralded the formation of the Wire System Safety Interagency Working Group.
"With the airline mergers we are reading about on a daily basis, it is the appropriate time for the airlines to let the public know what wires surround them when they board an aircraft," continued Block "in this way the passenger can make an informed decision whether to board that aircraft or not." [...and, if customers start walking off aircraft as a result, it will be fifty years before any more information is voluntarily disseminated --ed.]

"Federal safety investigators want the Federal Aviation Administration to shorten the time it has given airlines to correct a potentially dangerous heater problem on certain jetliners. They say the problem could result in fires on MD-80 and MD-90 series aircraft and on DC-9 jetliners.

Last spring, after two fires on Delta Air Lines jets, the FAA gave airlines five years to inspect some 642 aircraft and to replace all metalized Mylar-covered insulation.

But in a letter this week to the FAA, the National Transportation Safety Board said the insulation blankets should be replaced "at the earliest maintenance opportunity."

"Given the fire hazard posed by metalized Mylar-covered insulation blankets ... the safety Board is concerned that the five-year-compliance period is too long," NTSB acting Chairman Carol Carmody wrote in a letter to the FAA.

While the FAA order applies to all of the insulation in the affected aircraft, the NTSB recommendation applies only to insulation nearest the heaters, a factor that could influence the FAA to look favorably upon the recommendation.

"I don't know what impact that (moving up the timetable) would have," FAA spokesman Les Dorr said. "It might prove that this would prove feasible, but I just can't speculate."

The FAA has 90 days to formally respond to the NTSB's recommendation.

The potential hazard came to light on September 17, 1999, when a fire erupted during flight in the cargo compartment of a Delta MD-88. The crew declared an emergency and landed at Northern Kentucky International Airport, from which it had just departed.

Delta inspectors focused on the heaters used to keep ice from building up on air pressure measuring devices. They concluded that sharp bends in the heater elements could concentrate the heat and eventually burn the Mylar-covered insulation blankets around the heaters.

Delta inspected all 136 of its MD-88s and MD-90s and determined that 11 percent of the airplanes had some type of damage to their heaters.

On January 3, 2000, after the removal of the metalized insulation blankets, another heater malfunctioned on a Delta MD-88 after takeoff from Columbia, South Carolina. After the plane returned safely, inspectors found damage from electrical arcing, but the damage was contained to the heater itself.

"The risk of fire is very low in any event," Dorr said. "And we think that the order that we finalized in May was a prudent action with an acceptable level of safety." But he added the FAA will look carefully at the NTSB recommendation."

US FAA mulls in-flight entertainment system fixes

WASHINGTON, March 2 (Reuters) - U.S. aviation regulators on Friday proposed ordering airlines to improve the safety of in-flight entertainment systems by ensuring the flight crew can cut power to them in an emergency.
The Federal Aviation Administration (FAA) said an extensive review of current in-flight entertainment systems fitted as aftermarket modifications showed they could remain powered despite efforts to isolate them by the crew.
``The actions specified by these proposed orders are intended to assure the crew's ability to remove power from the entertainment system during unusual or emergency situations,'' the FAA said in a statement.
Airlines would have 18 months to take action on the problem once the FAA issues a final rule on the wiring of in-flight entertainment systems.
Costs per plane were estimated at between zero and $170,000 depending on whether the carrier chose to leave the system turned off during flight, removed the system or made extensive modifications.
Attention was drawn to the entertainment systems during the investigation of the fiery 1998 crash of a SwissAir MD-11 off the eastern coast of Canada. All 229 people aboard were killed. That crash remains under investigation by Canadian officials and the exact cause of the fire that occurred in the ceiling of the cockpit has not been announced.
FAA said a review of aftermarket in-flight entertainment systems showed the following range of problems:
-- the system could not be turned off without cutting power to required systems,

--the system could only be deactivated by pulling circuit breakers,
-- procedures for deactivation not available to crew.
An estimated 74 U.S.-registered aircraft would be affected by the 14 proposed airworthiness directives that apply to Boeing Co.
(NYSE:BA - news) 737, 747, 757, 767, DC-9 MD-80 and DC-10 aircraft. The Airbus A340 [ARBU.UL] is also covered.
Operators and other interested parties have until April 16 to submit comments on the FAA proposal or April 2 for the Airbus A340.
Four more similar directives affecting other aircraft models are being developed, FAA said.

FAA Proposes New In-Flight Rules

WASHINGTON (AP) -- Certain airlines would have to rewire their in-flight entertainment systems or keep them turned off during flights under new rules proposed Friday by the Federal Aviation Administration.

The proposed rules stem from an FAA investigation of the entertainment systems following the September 1998 crash of a Swissair plane flying to Geneva from New York. An electrical problem is suspected, though the cause remains under investigation.

In case of smoke, a burning smell, or an electrical short, airline crews would want to shut off nonessential electrical equipment to try to isolate the problem, but the entertainment systems on some aircraft can't be turned off without also shutting down other systems crucial to keeping the plane in the air.

FAA spokesman Les Dorr Jr. said the proposed rules were not connected to any possible cause of the Swissair accident, but the crash spurred the agency to begin looking at airplane entertainment systems.

At least 74 airplanes have entertainment systems that would need to be modified, most of them flown by American Airlines, Continental Airlines or Hawaiian Airlines.

The planes affected are certain Boeing, McDonnell Douglas and Airbus models.

Air carriers would have 18 months from the time the rule is adopted to make the necessary modifications. The FAA will accept comments on the proposal until next month.

 

U.S. LOOKS INTO FAA'S ALASKA AIR OVERSIGHT AGENCY'S RELATIONSHIP WITH AIRLINE QUESTIONED 

PAUL SHUKOVSKY and TRACY JOHNSON P-I REPORTERS

04/13/2000 Seattle Post-Intelligencer (Copyright 2000) Federal agents investigating the crash of Alaska Airlines Flight 261 and the airlines' maintenance operations are also examining the Federal Aviation Administration's oversight of the airline, according to criminal justice and aviation industry sources.

. . . Such an investigation would focus on whether Alaska encouraged criminally improper maintenance practices that were either sanctioned by or ignored by the FAA. . . . Alaska has been under investigation since at least December 1998, when agents of the FBI and the Department of Transportation's Office of the Inspector General seized company records in raids at the airline's Seattle offices and at its maintenance hangar in Oakland, Calif. . . . The investigation was expanded to include circumstances around the Jan. 31 crash of Alaska Flight 261, which killed 88 passengers and crew. . . . Former Department of Transportation Inspector General Mary Schiavo , whose job through much of the 1990s included being chief watchdog of FAA integrity, said yesterday reports that the FAA has been lax on Alaska reflect "the good-old-boy network" in aviation. "It is just a comfortable way of doing business, the path of least resistance," said Schiavo, who is now an attorney in private practice. "Usually, nothing happens. It's only when something happens that they get caught. Here it is very different because there are a lot of dead people" (from Flight 261). Schiavo said that when she was inspector general, she often got complaints from FAA inspectors overseeing many different airlines saying that "when they got tough, they got transferred." Yet Schiavo said she cannot recall a successful criminal prosecution of an FAA inspector for allowing violations of Federal Aviation Regulations. Prosecutors would have to prove the inspector knowingly violated the law and wasn't simply lax or incompetent.. "If they just did a horrible, sloppy job, the U.S. attorney wouldn't go criminal," Schiavo said. "You have to prove criminal intent and that is an extremely high standard."

Incident occurred Friday, December 29, 2000 at HONOLULU, HI

Aircraft: Lockheed L-1011, registration: N735D

Injuries: 300 Uninjured.

On December 29, 2000, about 2115 hours Hawaiian standard time, a Lockheed L-1011, N735D, operated by Delta Airlines as flight 219, experienced an electrical fire forward of the flight engineer's station while en route from San Francisco, California, to Honolulu, Hawaii. The flight was about 2 hours out of Honolulu, and continued for an uneventful landing, arriving at the gate at 2330. There were no injuries to the airline transport rated pilot, commercial rated co-pilot, airline transport rated flight engineer, 10 flight attendants, or the 287 passengers. The regularly scheduled domestic flight was operating under 14 CFR Part 121 and an instrument flight plan was filed. The flight originated at San Francisco at 1910.

The flight was cruising at 32,000 feet msl in clouds at the time of the incident. A few minutes before the incident the flight was experiencing a phenomenon called Saint Elmo's fire. The phenomenon is a discharge of static electricity often seen on airplanes flying through or near stormy weather. Static electricity from clouds collects on the airplane structure and discharges from sharp points in the form of visible light. This activity lasted for about 3 minutes, after which an arc was observed at the location of the windshield heat wire bundle above the first officer's side window. The crew donned their smoke goggles and masks. Two of the windshield heat circuit breakers had opened and the crew opened the remaining breakers. The panel covering the wire bundle area was opened for application of a Halon fire bottle on the burnt area of the bundle. Post incident examination of the affected wires revealed electrical arcing had occurred between the airplane structure, an Adel clamp, and a 30-wire bundle, with burning occurring to 20 of the wires. The wire bundle passes behind the flight engineer's station and overhead to the heated windshield.

USU HELPING TO MAKE AIR TRAVEL SAFER 

LOGAN -- The holidays mean more traveling, particularly by air. For those who fear airline tragedies, it can be especially stressful. Utah State University is working to alleviate some of those concerns. Students led by Professor Cynthia Furse, assistant professor in the electrical engineering department at USU, are developing an answer to a dilemma of airline safety that has caught the attention of the FAA, the National Transportation Safety Board, NASA, the Nuclear Regulatory Agency and the White House. The focus is on faulty wiring. 

Aging and damaged wires within the airplane is suspected as a possible cause of the crash of the TWA Flight 800 in which 230 people perished. Investigators are now looking closely at the problems caused by aging in airplane wiring systems that have resulted from the extended use of many aircrafts. Previously, planes were built to last for only a decade and then retired. Now planes are flying nearly double the time estimated when they were originally built, Furse said in a research report. 

Instead of retiring most planes, different components of the aircraft are being updated individually. While the different components are being replaced, the miles of wiring inside an airplane is not because it is too difficult and expensive to replace, Furse said. 

Aging wiring is visually inspected by technicians. However, many problems are too difficult to determine by this unsophisticated technique. Often when technicians are inspecting the wires they either miss problems or in the process of correcting damaged or malfunctioning wires they create more flaws. For these reasons various agencies and companies are developing different techniques to test the aging wires, according to Furse. 

One of the most promising of these techniques is being developed by the electrical engineering department at USU. 

Engineers at USU are developing a testing mechanism that will be a permanent fixture in the wiring system of aircraft. Because the mechanism is permanent, additional problems will not be created by technicians moving and bending wires when testing and examining them, Furse said. 

The mechanism called a "smart connector" includes a computer sensor, as well as electrodes, that send a signal down the wires. Problems are detected by the sensor analyzing the reflections of the signal sent down the wire, she said. 

With a "smart connector" pilots in the cockpit will be able to run a check of the wires minutes before takeoff. The "smart connector" would tell the pilot the location and severity of wiring problems, according to Furse. 

Planes could require more than a thousand "smart connectors" to monitor the wiring in a plane. For this reason, the engineers at USU have endeavored to create a connector that is inexpensive and lightweight. 

The implementation of this device not only has the power to save hundreds of lives, but also could save thousands of dollars in service and repairs, Furse said. 

The air division of the U.S. Navy is eagerly anticipating the completion of this project. They are already planning to implement "smart connectors" in many of their older planes. 

Furse said she anticipates that they will have a "smart connector" that is marketable in two years. 

However the engineers at USU do not plan to stop there. They have already begun research into developing a "smart wire" to be installed in new planes that would detect any problems and communicate them to the cockpit immediately.

November 4, 2000 - 757 Makes Emergency Landing

November 1, 2000 - Singapore Jet May Have Been On Wrong Runway 

SINGAPORE - The Singapore Airlines flight that crashed at Taipei's airport on Monday night, killing nearly 80 people, may have hit construction equipment while taking off on a runway closed for repairs, it emerged yesterday.

The Boeing 747-400 bound for Los Angeles with 159 passengers and 20 crew plunged to the ground and burst into flames shortly after take-off in a heavy storm that was originally thought to have been the cause of the crash.

But latest reports indicate the aircraft may have mistakenly used a runway under repair and may have struck parked equipment.

Seventy-six people people were killed instantly, and a pregnant woman died in hospital early yesterday. Of the other 102 people on board, 58 were still in hospital yesterday. Remarkably, 44 people escaped with barely a scratch.

The jet broke into three pieces and burned fiercely after crashing in typhoon winds and torrential rain.

Many of the corpses were charred beyond recognition, and some of the injured suffered horrific burns.

Investigators rushed to the disaster scene at Taiwan's international airport, with aviation experts from Singapore and the United States due to arrive on the island in the coming hours.

The "wrong runway" theory developed after the 48-year-old Malaysian pilot, C.K. Foong, who survived the crash, said he saw something on the runway and hit it just before take-off.

"He saw something there," Singapore Airlines' public affairs vice-president, Rick Clements, said in Singapore.

"It might have been a vehicle, it might have been a tyre, I don't know."

The Taiwan television channel TVBS speculated that the wrong runway had been used for the take-off, showing footage of a hydraulic mechanical shovel and cement blocks littering 05R runway, closed for maintenance and repair.

The two-metre high-shovel had clearly been hit in the front by something, the footage showed.

Taipei airport has two parallel runways, with a third used occasionally as a back-up.

A member of the investigating team from Taiwan's flight safety commission told reporters that the possibility the wrong runway had been used could not be ruled out, but investigations were continuing.

The search of the mangled wreckage was hampered by the typhoon winds and rains, which whipped up the debris. Charred bodies were laid out in a temporary morgue set up at the airport, while anguished relatives were brought to the site.

Investigators had already questioned three pilots, who survived the crash, and obtained copies of conversations between the pilots and air traffic controllers.

Chang You-heng, head of Taiwan's Civil Aeronautics Administration, said the causes of the tragedy were "still not clear", but added that "take-off was allowable under the weather conditions".

"Obviously the cockpit voice recorder will be able to answer a lot of questions," Mr Clements said in Singapore.

The crash was the first serious accident involving Singapore Airlines. In December 1997, 104 people died when a Boeing 737 operated by the airline's fully-owned subsidiary, Silk Air, crashed in Indonesia.

It shattered Singapore Airlines' otherwise proud safety record, which had previously included only a handful of technical incidents in its 28-year history.

The airline's chairman, Michael Fam, said: "This is a tragic day for all of us. We wish to express our sincere regrets to all concerned for this horrifying accident.

"Our immediate priority is to take care of all the affected passengers and crew and their respective families."

Singapore Airlines is the world's 11th-largest airline in terms of passenger traffic. It employs more than 13,000 people and serves more than 40 countries on every continent except South America.

Smoke, electrical problems force Chretien plane to land in Quebec City  

Updated 10:00 PM ET October 25, 2000(CP) - Losing power and with traces of smoke drifting through its cabin, the campaign plane bearing Prime Minister Jean Chretien and his entourage was forced to make an unscheduled landing in Quebec City late Wednesday.

None of the 59 people aboard the Boeing 737 were hurt after the pilot announced they had a problem with their electrical generator. All the lights inside went off and the aircraft began descending quickly. Electrical smoke wafted through the cabin, undetectable to the eye but its acrid smell was unmistakable. Chretien came to the back of the plane to assure reporters that everything was fine.
The Boeing 737 was still taxiing as the temperature rose, but Chretien remained in the back, joking with reporters and telling stories about prior aviation mishaps.
His wife, Aline, remained up front in her seat immediately behind the cockpit.
"We know all about these things," Chretien said calmly.
The pair were whisked away in a car immediately after the aircraft pulled up to the terminal building.
The landing was termed precautionary, a technical moniker that signals to air traffic controllers that the situation requires less priority than if an outright emergency had been declared.

Boeing near deal with UPS to convert 30 used planes for cargo

Boeing Jobs | Boeing Forum | BA Ticker
More Boeing News | Search: Boeing

ASSOCIATED PRESS and KIRO 7 EYEWITNESS NEWS NEW YORK -- Boeing Co., the world's largest manufacturer of airplanes, is close to a deal with United Parcel Service to convert 30 used jumbo jets into freighters for moving cargo, the Wall Street Journal reported Friday.

The companies have reached a tentative pact calling for the conversion of a fleet of MD-11 passenger planes into cargo jets. The deal, expected to be completed soon, is said to be worth up to $1.5 billion.

The companies are also in the early stages of discussions to convert larger 747 models for cargo use.

Boeing began expanding into aircraft modification two years ago. If the UPS deal is completed, it would provide a huge boost for the division, industry analysts say.

 

Wire Cracks Found in Tests of Older Jets

WASHINGTON (Reuters) - Cracked insulation was found in the wires of six older, recently retired aircraft, but the Federal Aviation Administration said Wednesday it had no immediate safety concerns. Engineers removed wires from high-stress areas of the aircraft that were more than 20 years old as part of a government-industry task force effort to determine the extent to which aging wiring may threaten safety. The aviation industry became sharply focused on wiring after the 1996 crash of a TWA Boeing 747. The investigation of a Swissair MD-11 crash off the 1998 has focused on wiring in the cockpit. USA Today reported Wednesday that, in one of the aircraft examined, a Lockheed L-1011 wide-bodied jet, four cracks were found in every 1,000 feet of wire tested.

Doomed Alaska jet may have lacked key parts - paper

Source: http://biz.yahoo.com/rf/001012/n12471604.html

SEATTLE, Oct 12 (Reuters) - A shortage of replacement parts for an
Alaska Airlines MD-80 jet undergoing maintenance 28 months before it
crashed may have played a role in a decision not to replace a key tail
mechanism, the Seattle Times reported on Thursday.

Documents from a National Transportation Safety Board (NTSB) probe of
the crash off the California coast last January that killed all 88 on
board show the word ``panic'' written next to a maintenance log entry
about locating new parts, the newspaper reported.

The findings were part of an NTSB interview with former Alaska mechanic
John Liotine, who recommended replacing the
jackscrew controlling the jet's horizontal stabiliser but was overruled.

The pilots of the doomed plane reported problems controlling the
stabiliser and the NTSB probe has implicated the jackscrew, which was
found coated with metal shards and might not have been properly
lubricated.

Liotine told federal regulators in 1998 that Alaska, the nation's 10th
largest airline and a subsidiary of Alaska Air Group Inc. (NYSE:ALK -
news), was falsifying maintenance records.

Alaska declined to comment on the latest report, citing NTSB
restrictions on investigation participants speaking publicly during a
probe.

Liotine told the NTSB that finding a replacement jackscrew, which could
cost up to $60,000, would have delayed the aircraft's return to service,
the newspaper reported.

The NTSB documents also showed that a pilots' union representative
claimed that investigators had found no evidence that Alaska had ordered
a replacement jackscrew, the paper reported.

In his initial test, Liotine had reported that the jackscrew was worn
almost to its legal limit and called for replacement. Other mechanics
ran several follow-up tests and recorded readings well within the legal
limit, overriding Liotine's recommendation.

Liotine's complaints triggered a Federal Aviation Administration probe
that found that six mechanics and inspectors at Alaska's Oakland,
Calif., facility had falsified records or violated regulations.

Alaska has referred to Liotine as a disgruntled employee who was placed
on paid leave in 1999 and ousted from his former position as union
president. He filed a libel suit against the company last month,
according to news reports.

The airline has taken numerous steps to beef up safety, including
sponsoring a comprehensive review of operations and
appointing a new vice president for safety. It has repeatedly insisted
it never knowingly allowed unsafe planes into service.

Scheduled 14 CFR 121 operation of CONTINENTAL AIRLINES Accident occurred OCT-01-00 at BIRMINGHAM, AL
Aircraft: McDonnell Douglas MD-80, registration: N69826
Injuries: 1 Minor, 146 Uninjured.

On October 1, 2000, at 1650 central daylight time, a McDonnell Douglas MD-80, N69826, operated by Continental Airlines as flight 1579, experienced an electrical fire during cruise flight at flight level 310 near Birmingham, Alabama. Flight 1579 was operated under the provisions of Title 14 Code of Federal Regulations Part 121 as a scheduled domestic passenger flight from Atlanta, Georgia, to Houston, Texas. The flight departed Hartsfield International Airport in Atlanta, Georgia, at approximately 1720 eastern daylight time with two air transport pilots, one jump-seat rider, three flight attendants, and 141 passengers on board. The airplane sustained minor damage and the jump-seat rider received minor injuries; there were no other injuries reported. Visual weather conditions prevailed at the time of the incident, and flight 1579 operated on an instrument flight rules flight plan. According to the pilot, approximately 15 minutes into the flight, the cockpit filled with smoke and he heard a loud popping sound and saw sparks emitting from the area of the jump-seat. The jump-seat rider reported that he heard an explosion and leaned forward to avoid heat which he felt on his left shoulder. When the jump-seat rider looked at his left shoulder he noticed that his shirt was burning. He extinguished the fire on his shirt, and put on his oxygen mask, since the cockpit was filled with smoke. The pilot declared an emergency and imitated a descending right turn. The flight diverted into Birmingham, Alabama, and landed without further incident. The preliminary examination of the airplane disclosed a 2 by 1 1/2-inch fire-damaged hole in the left jump-seat wall. Several heavy gauge electrical wires were severed and welded together on the opposite side of the wall. There were also four 50 ampere circuit breakers popped on the left circuit breaker panel behind the pilot's seat.

Subject: More On Wiring

This is what was published in the Seattle P-I today, Oct 5, 2000, in the business section under BRIEFS.

"FAA considers order to check 737 wiring The Federal Aviation Administration has proposed asking operators of some Boeing 737 jets to inspect a portion of the fuel-quantity measuring system for a potentially dangerous electrical fault.

The FAA said in a notice placed in the Federal Register on tuesday that it had received two reports of wires chafed down to the conductor in the fuel-measuring system in the right main fuel tanks of the 737s.

The FAA said its proposed airworthiness directive, giving six months for the work to be done, would apply to about 800 U. S. registered 737, -400, and -500 jets.

Boeing played down the safety hazard, saying there was not enough voltage in the line to pose an immediate risk. In response to 747 ignition concerns in 1997, boeing maintained that aircraft aircraft was designed to eliminate all ignition sources from the fuel system and that even if a spark were created, the energy would not be enough to ignite a center wing tank."

October 2, 2000 - Plane Makes Emergency Landing BIRMINGHAM, Alabama (USA) - An electrical fire in the cockpit of a Continental Airlines jet headed to Dallas forced the crew to make an emergency landing at Birmingham International Airport, an airline spokeswoman said.

A crew member sitting behind the pilot on Flight 1579 from Atlanta suffered minor burns, spokeswoman Erica Roy said. There were no other injuries, she said, and the fire was out when the McDonnell Douglas DC-9 carrying 147 passengers and crew landed at about 5 p.m. Sunday.

The passengers were transferred to another Continental plane, Roy said.

4. REVIEW AND UPDATE STANDARD PRACTICES FOR WIRING
The FAA has recommended that operators and the OEM develop a customized standard wiring practices manual to clarify and simplify electrical system installation and repair practices. This manual provides procedures for all types of electrical parts, some of which may not be used by a particular maintenance or repair facility. Removing unnecessary information and tailoring the procedures to specific repair facilities are expected to streamline the repair of electrical components.

In addition, the FAA recommended that a process that trains maintenance personnel to recognize aging effects on electrical systems and alerts them to proper repair procedures be defined.

EU Plans Air Safety Agency BRUSSELS, Belgium (AP) _

The European Union's head office Wednesday revealed plans to create an aviation safety agency. ``The EU will at last have the means to conduct a genuine aviation safety policy,'' said EU Transport Commissioner Loyola de Palacio in a statement. The proposed agency would be responsible for drawing up and regulating EU-wide airplane safety and security standards. ``The agency will encourage the harmonization of technical rules and especially ensure their uniform application,'' the Commission said in a statement. It added that the agency would be loosely styled on the U.S. Federal Aviation Administration, acting independently of national governments. The EU has already introduced regulations on noise and gas emissions for airplanes, which the agency will also enforce. Late last year, the Commission revealed plans to establish joint air traffic control of Europe's skies to replace a patchwork of national management systems and to reduce growing flight delays. The 15 EU nations are currently in talks with the aviation industry to work out plans for joint management. Increased cooperation among air-traffic authorities is already reducing flight delays according Eurocontrol, the agency that coordinates air traffic management in 39 European nations. In a statement this month, Eurocontrol said the average delay on commercial flights was 3.5 minutes, a 30 percent decrease on the August 1999 average, despite a 4 percent increase in the number of flights.

M2 Communications - An SAS aircraft had to land with smoke in the cabin on Sunday (10 September), the third such occurrence within the last six months.

The aircraft, a Ragna Viking (SK1561), was en route from Norway's Gardermoen airport in Oslo to Paris, France when it was forced to make a controlled emergency landing at Torp's Sandefjord airport, Norway.

The aircraft reportedly had 48 passengers aboard, none of whom were thought to be injured. SAS grounded the aircraft upon landing as a precaution, and said that it was possible that the smoke was caused by a short circuit in the cockpit. According to Aftenposten, a daily Norwegian newspaper, SAS has confirmed that this incident was not the first of its kind.

The Norwegian accident investigation commission has said that the incident should be regarded as serious when seen in connection with the other incidents aboard SAS aircraft as well as related incidents on a global scale and the Swissair crash off the Canadian east coast last year. Finn Heimdal, the head of the commission, speculated that the increasing amount of electronic equipment in aircraft cockpits might increase the risk of fire.

According to Heimdal, there are more reports of smoke in the cockpits of Norwegian aircraft than the average for other countries.

Sep 11, 2000 

Delegates at this week's Aircraft Quality and Safety Conference in Brussels will hear that a new risk assessment system rates Air Canada as the world's safest airline.

The new league table, backed by major industry and an international development bank, takes into account safety factors such as fleet composition, management structure and safety regulations in the the airline's home country, as well as its accident record.

According to the London Sunday Times the system, developed by a former test pilot, calculates that passengers traveling with Air Canada have only a one in 1.3 million chance of being involved in any kind of accident.

Those odds come down to 1 in 333 on the worst rated carrier, Air Georgia.

Two Australian airlines, Qantas and Ansett, are rated number two and three; Germany's Lufthansa is fourth, with US majors American Airlines and United Airlines entering the top twenty at five and six.

John Trevett, who developed the system, has been backed by the European Bank for Reconstruction who were anxious to not to book staff on to airline's with poor safety records.

Mr Trevett told the UK newspaper: "The law has changed, so companies are increasingly keen to minimise their exposure to risk."

Despite a fall in overall accident rates last year large companies are
becoming concerned about the chances of being sued for booking employees on to an unsafe flight that is then involved in an accident.

The Trevett system has been adapted and developed by the International
Association of Oil and Gas Producers in association with the Shell company and the bank.

A Reinforcing Argument Support for the GAO position about how best to measure safety comes from an essay in the August 7, 1999 edition of New Scientist magazine. Author Andrew Weir asserted that deaths or accidents per distance traveled dilute the accident rate for airplanes in comparison to cars or trains. Further, he argued, while the accident risk in a car or train is more evenly spread across the journey, the opposite is true for airplanes, where 70 percent of the accidents occur on takeoff or landing, just 4 percent of the journey time.

For these reasons, Weir suggested, deaths should be measured against the number of journeys made. This is not quite the same as the departure metric suggested by the GAO above but certainly represents a related approach. Weir used "passenger journeys," so 100 people in a jetliner taking off represent 100 passenger journeys in one departure. Weir claimed the "passenger journey" metric is used by the insurance industry. "By this measure, air travel takes on a rather different complexion," Weir wrote. "Deaths per 100 million passenger journeys are, on average, 55 for airliners compared to 4.5 for cars, and 2.7 for trains. Only motorbikes, at 100 deaths per 100 million passenger journeys, are more risky than aircraft on this basis." Indeed, in the U.S. motorcycle drivers are sometimes referred to as "organ donors" because of their high accident rate.

Weir is saying that driving is ten times safer than flying, when measured as deaths per journeys. Further, he argues, the fatal accident rate in commercial aviation has stabilized at about one per 1.5 million departures, and it has stubbornly remained there despite the infusion into the fleet of the latest generation of jets equipped with fly-by-wire (FBW) and flight management technology.

From Air Safety Week; Weir's take on air safety flies in the face of the widely held industry view that flying is the safest mode of travel. Alan Downs' 1997 book, "Beyond the Looking Glass - Overcoming the Seductive Culture of Corporate Narcissism," may bear on the industry perspective of air safety. Downs points out that those listening only to the beat of their own corporate drum might not hear the locomotive of destructive libel bearing down the tracks on them. "A narcissistic company rarely handles criticism constructively,"

Downs writes. "Instead, it chooses to manipulate feedback to suit its own purposes. Some tactics used include putting a positive spin on news that is otherwise negative, and attacking the critic." (Note 1: For the full text of Weir's opinion essay, see this website: http://www.newscientist.com/ns/19990807/flightinto.html  . Note 2: We are indebted to Bart Crotty for bringing Down's observations on the cult of corporate narcissism to our attention.)

--- U.S. to determine if old planes are less safe ---
Alarmed by aged wiring's possible role in dooming TWA Flight 800, a U.S. safety official ordered a study on Wednesday into possible links between older aircraft and accidents and whether passengers should be told the age of planes they board. Jim Hall, head of the National Transportation Safety Board, acted after staff investigators said a short circuit in aging wiring probably caused the explosion of TWA Flight 800, a 25-year-old Boeing 747-100.
August 22, 2000 - AirTran Emergency Was More Dire Than Known, Wash Post Says WASHINGTON (USA) - 

When AirTran Airways Inc. pilots made an emergency landing in Greensboro, North Carolina two weeks ago, their plane may have been in more serious trouble than first indicated, the Washington Post reported, citing unnamed sources close to a federal investigation.

When smoke from an electrical fire began filling the cabin, the pilots of the McDonnell Douglas Corp. DC-9 weren't certain they could make it back to Greensboro and considered landing the aircraft on a highway, the newspaper reported. The problem began with a circuit-breaker panel in the cockpit and wasn't routine, the Post said, citing unnamed sources.

The plane involved in the emergency landing was originally built for Turkish Airlines in 1970 and was sold to ValuJet in 1994, the Post said. Since ValuJet merged with AirTran in 1997 following a DC-9 disaster in the Florida Everglades, all of the planes have been re-certified for safety, an AirTran spokesman told the newspaper.

McDonnell Douglas, a unit of Boeing Co., produces military and commercial aircraft.

    This Forecast of Future Accident Activity is another graphic, prepared by the Boeing Company engineers. It is a bit cluttered but there is an important message here. The left hand scale can be read as either millions of aircraft departures or as hull losses (a euphemism for accidents). Notice in the lower right that the world’s hull loss accident rate (in red) has leveled off for the last few years at about 1 loss per million departures. Also the green line which indicates millions of departures continues to climb. With a constant accident rate (red line) – and more and more departures (green line) – one can forecast that there will be more accidents per year. Hull losses for the past three years have been about 20 per year. We can expect that number to increase.
    Also we should consider the number of transport airplanes currently in service. There are about 14,400. By 2016 we expect to see about 25,600 airliners operating worldwide. Again with a constant accident rate (the red line) and more than 10,000 new airliners joining the fleet, we can expect to see an increase in the number of accidents per year.

 

    Regional Perspective
    This graphic, prepared by the Boeing Company, highlights the major differences in accident rates in various parts of the world. The U.S., Canada, Europe and Oceania are fortunate to have recorded between .3 and .7 accidents per million departures. On the other hand, Africa’s losses are extremely high, followed by Latin America and the Caribbean, China and the Middle East. If we view this data as an indicator, or a prediction of where future accidents are likely to occur, then we can expect to see numerous accidents in Africa, Latin America and the Caribbean, China and the Middle East.

 

NEED THIRD IN COCKPIT

High-tech cockpit safety devices are great, but one that was thrown out in the interest of economy was the flight engineer (AW&ST July 17, p. 66). Instead of putting someone in the jump seat to see what distractions and interruptions occur, why not put a third pilot there to:

  • Monitor the pilot flying while the other pilot is distracted by setting the flight management system or communicating.
  • Ensure that checklist items are performed appropriately.
  • Help scan for traffic.
  • Coordinate with flight attendants.
  • Monitor instrument approaches and settings on navaids.
  • Troubleshoot problems in the cockpit or elsewhere such as unruly passengers.

Flight engineer certificates wouldn't be needed, and the airplane wouldn't have to be modified. If airlines decide to use exter- nal TV cameras to monitor tires, brakes and engines during takeoff or for suspected problems, the extra pilot could have the responsibility. As always, the question is: "What price safety?"

Hong Kong-New York Flight Makes Detour To Ontario

747United Airlines' recent flight cancellation problems aren't restricted just to weather and labor issues. Last Saturday afternoon, a United 747 carrying 320 passengers from Hong Kong to New York had to land in North Bay, Ontario, after the crew reported hydraulic problems. According to an AVweb reader with a friend on the plane, after a safe landing and while taxiing off the runway, the plane went totally dead -- no battery power, no APU, no nothing. The passengers sat on the dead aircraft for four hours waiting for a ladder truck to get them off, since the North Bay airport was not equipped to handle wide-body transports. United Airlines sent another 747 from Chicago to pick up the passengers, but a problem forced it to return. The third time was a charm though, as another United plane successfully arrived at North Bay to carry the weary travelers to New York on Sunday morning.

AirTran Airways Flight 913 makes emergency landing

It's always better to be down here wishing you were up there than up there wishing you were down here.
(File Photo by Chris Barrow)

GREENSBORO, N.C. (AP) - A cockpit fire forced an airplane with 62 people on board to make an emergency landing in North Carolina on Tuesday. Five people were treated for minor injuries.

AirTran Flight 913 from Greensboro to Atlanta reported the fire when it was about 20 miles south of Greensboro, said Kathleen Bergen, a spokeswoman for the Federal Aviation Administration in Atlanta. The DC-9 turned around and landed safely about 3:45 p.m. at Piedmont Triad International Airport in Greensboro, authorities said.

``There was quite a bit of smoke coming out of the aircraft when they opened the door,'' Bergen said.

Two men and two women suffering from smoke inhalation and a man with a twisted knee were taken to the hospital, officials said. All the injuries were minor.

AirTran, based in Orlando, Fla., is the former ValuJet, whose plane crashed in the Everglades in May 1996, killing 110 people. The airline's jet repair company was convicted of hazardous waste violations in that crash.

AirTran: Where There's Smoke...

Every takeoff is optional.  Every landing is mandatory.Tuesday's in-flight fire aboard an AirTran DC-9 shortly after taking off from Greensboro, N.C. (GSO) had some observers experiencing déjà vu all over again. Flight 913 had just taken of when the crew declared an emergency, told controllers they had smoke in the cockpit, and requested an immediate landing back at GSO. The flight landed safety, although nine of the 56 passengers and five crewmembers were apparently treated for smoke inhalation and injuries sustained during the plane's evacuation. According to the FAA, fire was seen behind the cockpit and in the forward galley after the plane came to a stop. AirTran is the successor to ValuJet, which became well known after the May 1996 crash of another DC-9 into the Florida Everglades killed all 110 aboard. That crash was attributed to a fire caused by hazardous material -- improperly shipped oxygen generators.

You will recall that I sent you (a couple of weeks back) a copy of the FAA AD (based upon the French AD) that mentions the wiring faults that led to this trim runaway and the Thai A310 crash at Surat Thani - as well as the near accident at Dubai (Emirates A310). This constitutes evidence that wiring's not just a Boeing problem. In that AD it also mentioned that it was an interim fix and that further (Airbus) action was anticipated.

 More AIR CRASH RESCUE NEWS:------

July 21, 2000 - Malfunction Caused Fatal Plane Crash, Reports BANGKOK, Thailand - Equipment failure has been identified as the cause of an air disaster that claimed 101 lives in Thailand, according to press reports.

A report from Thailand's state news agency says the "trim" malfunction caused Thai Airways International Airbus A310-200 aircraft to crash in December 1998.

The report, posted on the website of the Thai News Agency, cited an unidentified source on the government panel.

No findings have been officially released.

"An examination of black-box data by a French neutral organisation also confirmed that the trim system of the plane had malfunctioned, but did not indicate the cause of the problem," the agency said.

It quoted the source saying that the unidentified organisation had been asked to double-check and clearly indicate the cause of the trim problem.

Trim, which regulates whether a plane is kept level or heads up or down, can be controlled automatically by the airplane or manually by the pilot.

There was no official confirmation of the findings from either Airbus Industrie, Thailand's Aviation Department or Thai Airways.

Transport Minister Suthep Thaugsuban, whose sister was killed in the crash, has said that the report would be issued early this year. There has been no explanation for the delay.

The flight from Bangkok to Surat Thani, 330 miles to the south, crashed after the plane failed to pull up after the pilot aborted a third attempted landing in rain at night.

The plane crashed into a swamp near the small airport. Forty-five people survived.

The pilot, co-pilot and nine crew were among the 101 people killed. So were 14 of 26 foreign passengers, the dead including citizens of the United States, Austria, Great Britain, Finland, Germany, Japan and Norway.

AIR CRASH RESCUE NEWS:

July 21, 2000 - Northwest Makes Emergency Landing FLINT, Michigan (USA) - A Northwest Airlines plane made an emergency landing Friday morning because of a possible fire in the cabin.

There was smoke in the rear of the cabin, but it turned out there was no fire, airline spokesman Jon Austin said. Mechanics were looking for the cause.

The DC-9 left Flint's Bishop International Airport at 6:50 a.m. en route to Detroit, but returned to Flint shortly afterward.

The passengers were evacuated down the emergency slides as a precaution, Austin said. One person complained of a sprained knee or ankle, but no other injuries were reported.

Flight 364 was carrying 78 passengers and five crew members. Northwest sent another plane to the airport to transport the passengers.

The Federal Aviation Administration was investigating.

DALLAS (Reuters) - Mon 17 July 00

 Two American Airlines MD-80 jets were forced
to make separate emergency landings on Monday, one after a report
of smoke in the cockpit and the other with possible stabilizer
problems, officials said. American's flight 1258 returned to
Dallas/Fort Worth International Airport after take-off on Monday
and all 128 passengers left by the emergency exits after the crew
reported smoke, the airline said. The jetliner bound for Orlando
pulled onto a taxiway at the airport before the passengers and
five crew went out through the overwing exits and front and rear
stairs. American said passengers were bused to the terminal and
would be flown to Orlando on another plane. The MD-80 was taken
out of service to find the source of the smoke.

FAA Orders Inspections of MD-11 Cargo Compartment Wiring

WASHINGTON 4/20/99-

Based on a recent report of a burnt insulation blanket, the Federal Aviation Administration (FAA) has ordered operators of 45 U.S.-registered MD-11s to verify the installation of a wire harness support bracket and clamp in the lower center cargo compartment. A missing bracket and clamp could cause a wire bundle to contact the insulation blanket and rub against the fuselage frame, producing a possible fire source.

This Emergency Airworthiness Directive (AD) does not appear to be related to the Swissair accident. However, it is prompted by information from the agency's continuous post-accident review of the service experience of the MD-11 fleet. While performing routine maintenance on an MD-11, mechanics found evidence of wire chafing in the cargo loader control unit and burnt insulation. They also discovered that a wiring harness support bracket and clamp that supports a wire bundle may not have been installed on the aircraft.

This AD affects MD-11s equipped with a 72-inch cargo door. MD-11s with a 104-inch cargo door have a different wire bundle configuration. Operators of the affected aircraft are required to perform inspections, verify the installation of the bracket and clamp, and repair any damaged wires within five days. All findings must be reported to the FAA within 10 days after completion of the inspections.

There are 45 U.S.-registered aircraft, both passenger and cargo, affected by this AD out of a total of 89 aircraft worldwide. Operators include American Airlines, Delta Air Lines, World Airways, Federal Express Corporation, and The Boeing Company. The total estimated cost to inspect the U.S. fleet is $8,100, $180 per aircraft.

July 14, 2000 - FAA Explores Nitrogen To Prevent TWA 800 Repeat WASHINGTON (USA)- 

A shot of nitrogen into the fuel tanks of passenger aircraft in hot weather may be the ultimate defense against a repeat of the explosion of a TWA jumbo jet off New York nearly four years ago.

The Federal Aviation Administration is due to begin testing that idea next month when fuel tanks in a Boeing 737 will be "inerted" with nitrogen gas in a new program conducted jointly with aircraft manufacturer Boeing Co., agency officials said Thursday.

Advances in gas-separation technology have brought costs down to where it may be feasible at the airport to fill the vapor space in aircraft fuel tanks with nitrogen-rich air that cannot support combustion.

FAA Associate Administrator Tom McSweeny said the technology, described by some as "de-icing for summer", looked promising. "We are excited enough about it to want to keep pushing it," he told reporters.

TWA Flight 800 fell to the sea in flames shortly after take off from New York bound for Paris on July 17, 1996.

All 230 people on board were killed in the tragedy traced by investigators to the explosion of the Boeing 747s center fuel tank though the precise ignition source remains elusive.

The National Transportation Safety Board, ruling out a bomb or a missile as the cause, has encouraged the FAA and the aviation industry to do more to eliminate ignition sources and find ways to reduce the flammability of fuel tanks.

Fuel tank explosions are rare and only a 1990 blast in the Philippines involving a Boeing 737 on the ground is thought to have a direct resemblance to the TWA 800 accident.

Nevertheless, since the crash, the FAA has issued 37 airworthiness directives that mandate action on items ranging from fuel tank inspections to modifications of pumps and wiring related to the tanks.

A final meeting of the safety board on the crash is due to take place in late August. A review of the post-crash research and lessons learned is expected to conclude without a definitive answer to what touched off the blast.

"It's the most intensely investigated accident in aviation history," FAA aircraft certification director Beth Erickson said. "We all know there was a fuel tank explosion but the ignition source for that explosion remains unknown."

In other developments, McSweeny and Erickson said work was advancing more quickly than expected on better circuit breakers for planes that would trip sooner, much like a safety power outlets in many bathrooms today.

FAA also plans to issue advice to airlines to use cool air supplied at the terminal rather than on-board air conditioning when waiting at the gate.

TWA 800 sat for hours at New York's John F. Kennedy Airport running its internal air conditioning units that are located underneath the center fuel tank. During the probe it emerged that the U.S. Air Force had been concerned for years about such heating and the increased chances of a fire or blast.

Using external air conditioning could lower the time a plane's center tanks were potentially flammable to 22 percent of the plane's operational time from 30 percent, FAA said.

But it was inerting that Erickson said held so much promise, with calculations it could decrease the period during which the center tank was potentially flammable to just two percent.

A recent study requested by the FAA said the ground infrastructure required for inerting would cost $1.6 billion over 13 years. It remains to be seen how much modification of planes might be required and at what cost.

 

FUEL TANK SAFETY INITIATIVE TARGETS WORLD’S AIRLINERS

 As a result of the TWA 800 flight 800 explosion in 1996, the U.S. Federal Aviation Administration (FAA) is working on a three-pronged rulemaking package that includes setting new certification standards and mandatory maintenance  instructions on fuel systems for newly designed aircraft worldwide.  It also calls for design reviews and mandatory maintenance on existing aircraft.

 The regulation, affecting 6,000 aircraft in the current transport fleet with 30 or more seats, would require a design review revalidating the fuel tank system design to ensure that failures could not create ignition sources within the fuel tanks.

 Manufacturers would also be required to design specific programs for the maintenance and inspection of the tanks to ensure the continued safety of fuel tank systems.

 The proposal also calls for changes to aircraft operating rules, requiring operators to develop and implement an FAA-approved maintenance and inspection program for fuel tanks.

 The proposed design standards call for a new flammability standard for newly designed aircraft, which minimizes the development of combustible vapors in fuel tanks.

 Alternatively, manufacturers must provide a means to prevent catastrophic damage if ignition does occur.  The new standard also requires assessment of whether ignition sources could be created by failures and for the development of mandatory fuel tank  maintenance and inspection programs for newly designed aircraft.

 Aircraft affected include these aircraft and manufacturers: Airbus, Bombardier, De Havilland, ATR, Dornier, Embraer, Boeing, Fokker, Lockheed, Saab and British Aerospace.

ICAO DRAFTING POST-ACCIDENT ‘FAMILY ASSISTANCE’ GUIDANCE

On the recommendations of the Spanish and U.S. delegations to the 32nd Assembly Meeting of the International Civil Aviation Organization (ICAO) in Montreal, Canada, last fall, ICAO is developing guidance materials for all member nations on how to assist victims and family members of those killed and injured in major aviation accidents.

At the assembly meeting, a family assistance resolution was adopted that also urges ICAO nations to review, develop, and implement family assistance programs. A key part of resolution calls for a homogeneous global solution to dealing with the victims of aircraft accidents and their families, irrespective of the nationality of the victims or where the accidents may occur.

The U.S. National Transportation Safety Board (NTSB) has been implementing a comprehensive family assistance program over the past few years. In legislation and by executive order, all airlines that fly in and out of the U.S., including foreign flag carriers, are required to have a family assistance program approved by both the NTSB and U.S. DOT. The NTSB also has a full time family affairs staff and is assisting ICAO in developing guidance.

THE NETHERLANDS INAUGURATES NEW INDEPENDENT, MULTI-MODAL SAFETY BOARD

 The new independent, multi-modal Dutch Transport Safety Board (DTSB), (Raad voor de Transportveiligheid, RVTV), was officially inaugurated on June 30 in The Hague, The Netherlands. The DTSB brings together former separate accident investigation boards of the different transport sectors: the Dutch Railway Accident Investigation Board, the Dutch Maritime Board, the Netherlands Aviation Safety Board and the former Dutch Road Safety Council.

 The new DTSB is structured as one overall independent safety board with four chambers responsible for accident investigation in their sector – air, rail, marine and highway.  A major distinction of the DTSB is that it is an independent government organization and is not part of the Ministry of Transport, Public Works and Water Management.

 The board is comprised of the chairman and vice-chairman of each chamber, together with the overall board chairman, Pieter van Vollenhoven, who also chairs the International Transportation Safety Association (ITSA), and several general transport safety experts.  The staff of the new DTSB will consist of about 32 employees, including many staff and chief investigators of the old modal boards.

Return to Newsletter Index

Out of the June 21-22 meeting of the Aircraft Wiring and Inert Gas Generator (AWIGG) working group meeting in Indianapolis, Ind., participants offered a number of comments (see ASW, June 26). A high level of thinking and a commitment to the issue characterize the participants' post-meeting inputs:

"So far in the discussion of aging effect on aircraft wire, the focus has been on defects/damage that might cause a short and an arcing event and/or a fire. Damage to 'signal' (low energy) is discounted. However, there are high impedance/high gain circuits that can be disturbed by very small leakage currents. A couple examples are **flux gates and FQIS (Fuel Quantity Indication Systems). I would like to hear a presentation detailing all such systems and the performance impact of leakage currents/stray voltage that can result from small insulation cracks in the presence of contamination and moisture. I believe there are some significant flight safety risks, especially in IFR conditions that can arise for NAV, COM and flight control signal paths being disturbed."

"Fire detection and suppression: Be an advocate for funding and then testing to determine airflow and 'leakage' in compartments that still need protection. Encourage the aviation industry to expand underutilized 'Class D' cargo fire suppression systems in to the E&E (electronics and equipment bay), cockpit, lavatory, overhead bin, and other fuselage compartments. Find an airline to act as a leader who will expand protection into these compartments even though no regulations yet exist which require the protection or system."

"There appears to be a lack of 'hard' data from the airlines or operators on the quantity and frequency of wiring problems. I would like to see the AWIGG members try and quantify this and share the data with the AWIGG."

"In the past two years, AWIGG has served as an information exchange for many new ideas to fight and prevent wire failures and aircraft fires. Some ideas are ready for prime time, but many need more work and funding.

How about another AWIGG 'panel' to...select some promising ideas to NASA, FAA, or 'the Hill' (U.S. Congress) for more development and implementation?"

"Possible subject for AWIGG coverage: Standard Repair Procedures - primary insulation damage, shield damage tolerance, chafe protection methods (tape wrap), convoluted tubing installation."

"Possible initiatives: Move toward pushing for inspection requirements for wiring on both commercial and military vehicles. Need emphasis for encouraging and developing test methods, procedures and equipment which will work in the real world. Some of the good ideas which are 'out there' need to be further developed and combined (getting past proprietary issues) so we can improve passenger and operator safety. Need emphasis for using minimum standards as requirements for aircraft design (e.g., Mil-W-5088 or SAE spec as contractual requirement). This is needed to avoid having decision-makers overlook or overrule their technical advisors."

I remember the automobile industry carping about having to install seatbelts and later airbags, not to mention pollution control devices ... they were too expensive, impractical ... would make cars unaffordable to average Americans. Of course in the end, necessity was the mother of invention, and somehow they managed to make these improvements.

I would expect Mr. Goldfarb's remarks to come from the airline industry, not those charged with regulating them in the public interest. I believe that the FAA has failed miserably as an advocate for the flying public. Personally, I'm not very interested in passengers' rights movement.

For obvious reasons, the only passengers' right I care about is the right to arrive alive. But the indignities that air carriers subject their customers to are endemic of a regulatory body that is in bed with the industry. I've said before that we can't blame the police for the behavior of criminals, nor can we blame the FAA for gross neglect on the part of an air carrier or aircraft manufacturers. But as a matter of public policy, where there is crime, we need police.

When an industry can't be trusted to act responsibly, we need to regulate its practices.

Why isn't this an obvious problem that attracts the attention of the public and the legislative branch of government?

Perhaps the double-talk has something to do with it. The FAA claims to certify new equipment that is to be installed in commercial aircraft. The people who actually perform this function are not, however, employees of the FAA, but rather receive their compensation from companies like Boeing and Santa Barbara Aerospace.

In my humble opinion, that's the equivalent of no regulation at all. And why do FAA officials defend this pathetic system. Might it have something to do with the fact that many of the "Designated Engineering Representatives" who profit handsomely under the current scheme of things are former FAA employees?  I've heard this program (DER) called a supplemental retirement income plan for the FAA. Isn't Mr. Goldfarb an industry consultant these days?  How nice for him.

It disgusts me to hear arrogant bureaucrat asses defend their moronic little agency. The FAA is broken. It's time to get it fixed!

AIR CRASH RESCUE NEWS:

July 4, 2000 - Emergency Landing in Florida FORT MYERS, Florida (USA) - A flight bound for Miami from San Francisco made an emergency landing at Southwest Florida International Airport after the pilot reported a smoky haze in the cockpit.

United Airlines flight 985 landed safely at 10:25 p.m. Monday. None of the

157 people on board was injured, airport spokeswoman Susan Sanders said.

About half the passengers chose to rent cars in Fort Myers and drive the last

150 miles to Miami, rather than wait to continue on with their flight.

The plane, a Boeing 767, was diverted to Fort Myers when the pilot reported the haze, Sanders said.

Swissair crash cases head for mediation

By David Morgan

PHILADELPHIA, June 28 (Reuters) - A U.S. judge will begin mediating negotiations next month in 15 lawsuits stemming from the 1988 crash of SwissAir Flight 111 in hopes of encouraging individual settlements in the massive liability case, lawyers said on Wednesday.

Closed-door negotiations were set to start July 17 before U.S. District Judge James Giles in lawsuits selected by attorneys for the plaintiffs and continue for about three weeks, possibly with other federal judges or magistrates serving as mediators.

``He wants to get the settlement process rolling sooner rather than later. He obviously wants to encourage that,'' said SwissAir attorney Michael Holland.

SwissAir , SairGroup, SR Technics AG, Boeing Co. (NYSE:BA - news), SwissAir code-share partner Delta Air Lines Inc. (NYSE:DAL - news) and Interactive Flight Technologies Inc. have all been named as defendants in 167 separate lawsuits seeking a combined $16 billion in damages.

Plaintiffs are the families of 229 people who died aboard SwissAir Flight 111 off Peggy's Cove, Nova Scotia, on Sept. 2, 1998, when the Boeing-made MD-11 aircraft plunged into the Atlantic Ocean killing everyone on board.

Since last August, when the SwissAir case first came before Giles, only half a dozen suits have been settled despite the judge'
