July 9, 2003 — As a Boeing 757 airliner
climbed to 14,000 feet in March, a routine
takeoff suddenly became an emergency. Sparks
and smoke came out of the passenger cabin's
in-flight entertainment system, cockpit
instrument lights lit up, and the rudder and
control wheel moved.
The pilots, who reported
the incident to a government safety database,
said they returned for an "uneventful" landing.
The database doesn't identify the airline
involved or the U.S. airport the flight diverted
to, but the timing of the event was significant.
It was the same month the
Canadian government concluded that entertainment
system wiring may have caused or contributed to
a fire that sent a Swissair jet into the ocean
near Nova Scotia in 1998, killing all 229
aboard. The Canadian Transportation Safety Board
said an entertainment system wire or another
wire short-circuited, creating a fiery electric
arc that ignited acoustic insulation blankets.
Despite intense scrutiny
after the Swissair accident, in-flight
entertainment systems continue to malfunction,
and U.S. airlines are still being ordered to
modify some systems.
A USA TODAY analysis
found that since the Swissair accident, U.S.
airlines have sent the Federal Aviation
Administration 60 "service difficulty reports"
about in-flight entertainment systems, many
involving fire, smoke or sparks. Airlines are
required by the FAA to report within 72 hours
each "failure, malfunction or defect" that
endangers an aircraft's safe operation.
Pilots and flight
attendants have voluntarily reported to another
government database 20 incidents of
entertainment system problems. It's unknown how
many of those incidents are also included in the
service difficulty reports.
The FAA has also sent 22
orders to ban, modify or repair certain
entertainment systems. Most of those orders
resulted from an investigation done by the
agency after the Swissair crash.
"The time is long past
that we can consider these systems as
risk-free," says Jim Shaw, a pilot and a safety
expert for the Air Line Pilots Association
union. "I know many instances where problems
with in-flight entertainment systems created
smoke and fire events," he says, speaking for
himself. The union wouldn't comment.
Many jets have
traditional in-flight entertainment systems with
overhead movie screens shared by rows of
passengers. Others, particularly new, wide-body
planes flying international routes, contain more
sophisticated equipment with individual screens
that allow passengers to choose a movie, play
games, shop or gamble. Upstart airline JetBlue
offers live satellite TV on monitors at every
seat.
Some major airlines offer
video or audio entertainment on most of their
planes, while some, such as Southwest, have no
jets with such equipment.
Consultant Wale Adepoju
estimates that 5,100 of 11,650 planes worldwide
with 100 or more seats have some form of
entertainment system, and about 2,000 of those
aircraft have at least some seats equipped with
individual video screens. Of about 3,700
wide-body aircraft in the global airline fleet,
nearly 80% have some form of entertainment
system, Adepoju says.
Manufacturers insist that
the most sophisticated entertainment systems, as
well as older ones, are safe and meet FAA
standards. They blame the type installed on
Swissair, which was banned a year after the
crash, for giving everyone in the industry a bad
name.
That system, built by a
Phoenix company now out of the airline business,
was put on to replace an existing system and
pioneered interactive entertainment at each
seat. But, as a USA TODAY investigation found in
February, it was improperly designed, installed
and certified by contractors without adequate
FAA oversight. The General Accounting Office and
the Transportation Department's inspector
general recently began investigating the matter.
Other systems, though,
have had problems since the Swissair accident.
Safety experts say the number of service
difficulty reports about entertainment system
problems endangering passenger safety during the
past two years could far exceed the 60 received
by the FAA.
"The 60 reports are
probably just the tip of the iceberg," says Alex
Richman, whose company, AlgoPlus Consulting,
analyzes FAA data for some aircraft operators.
"More incidents probably go unreported than are
reported."
The FAA's 22 orders to
ban, modify or repair entertainment systems
involve those that airlines installed to replace
previous ones. The orders apply to the equipment
on eight types of Boeing, McDonnell Douglas and
Airbus jets.
More pounds, more
wires
An entertainment system
adds thousands of pounds to a jet. It consists
of more than 2,000 parts and, on a fully
equipped wide-body jet, uses about 4 1/2 miles
of wire, says Greg Steiner, a vice president at
entertainment system manufacturer Rockwell
Collins.
Ed Block, a former
Defense Department employee involved in wiring
purchases, inspected wiring on various jets for
an FAA task force and for Swissair victims'
families. It's his opinion that all in-flight
entertainment systems should be banned because
they have electrical wiring and components that
can malfunction and start a fire during flight.
The aviation industry has
been grappling for years with problems of
cracked and deteriorated wiring causing fires
and emergency landings, he says. Adding four
miles of entertainment system wire to a jet that
may have more than 100 miles of other wires is
"like throwing gas on a fire."
Ken Adams, who was the
Air Line Pilots Association's lead investigator
in the Swissair crash, doesn't think the systems
must be scrapped. But he says they need to be
better designed and suggests studying the use of
fiber-optics instead of electrical wiring. "Any
time you're adding more and more electrical
systems, you're compounding the problem," he
says.
In a statement to USA
TODAY, the FAA says entertainment systems are
safe and that it "takes a very rigorous approach
to approving non-essential systems." The agency
says it has done in-depth reviews of the
entertainment systems on airplanes, has taken
action to make sure no system in use has the
same design features as the one on the Swissair
jet, and has issued directives designed to
prevent any unsafe conditions from developing.
Manufacturers say their
systems must meet FAA and aircraft
manufacturers' standards and tests. "Safety is
the absolute first priority," says Rob Brookler
of the World Airline Entertainment Association,
which represents manufacturers, suppliers and
airlines. "We'd support any procedures that
would further enhance the safety of the
systems."
The Air Transport
Association, a trade group representing U.S.
airlines, refused to comment about in-flight
entertainment systems. Northwest Airlines, which
flies many long-distance flights with such
systems aboard, says it buys "the appropriate,
proven system recommended by the aircraft
manufacturer." JetBlue says the airline's
in-seat live television systems were certified
by the FAA. The airline says it has had "no
issues" with them.
United Airlines says its
in-flight entertainment systems are safe because
they are continuously monitored by its
maintenance department "for any irregularities
or reliability issues that require attention."
United says its systems have not been cited in
any FAA orders and are not similar to those that
were on the Swissair plane that crashed.
Reports of problems
Most of the 60 reports
filed by airlines with the FAA, which were
provided to USA TODAY by AlgoPlus Consulting,
mention fire, smoke, sparks, an electrical
short-circuit or burning odor in the passenger
cabin. Among the confidential reports given to
NASA by airline flight crews, which NASA says
are not verified for accuracy:
• A flight attendant on a
Boeing 767 flight last August reported that she
became nauseated, her eyes and throat burned and
a passenger vomited after breathing fumes from a
malfunctioning video system.
• On an Airbus A-300
plane in December 2000, a flight attendant
reported passengers standing in the aisle during
landing as "smoke, sparks and a flame" came from
an entertainment system box under a passenger
seat.
• A pilot reported smoke
"pouring out" of an entertainment unit on a 767
international flight in April 2000.
• In February 1999, a
flight attendant on a McDonnell Douglas MD-11
flying over Alaska said it was hard to breathe
because of a burning wire odor coming from a
video system.
The FAA says such reports
from crew members are voluntary and can't be
used to decide how prevalent a problem is.
The 22 orders from the
FAA after the Swissair crash came when the
agency reviewed systems that, like the one on
the Swissair McDonnell Douglas MD-11 jet, were
put in as replacements between 1992 and 2000.
The orders involved systems on at least 182
planes, including removal of the entire system
on six Douglas DC-9s. It also ordered removal of
an unspecified number of systems on DC-10s and
767s. And corrections were ordered for some
systems on other 767s, 757s, 747s, 737s, MD-11s,
DC-10s and Airbus A-340s.
Ten of the 22 orders,
including one issued in December for an
unspecified number of 767-300s, instructed
airlines to install switches that allow the
systems to shed an electrical load or to be
turned off without affecting other aircraft
systems. Also in December, the FAA proposed that
some system components on some 737s and 757s be
inspected and the wiring possibly replaced.
Last month, an order took
effect requiring that airlines operating 37
767-300s install new electrical components in
the systems within 18 months.
In its statement, the FAA
said its orders to airlines about entertainment
systems are not a sign that planes equipped with
them operated unsafely, but are meant to prevent
unsafe conditions from developing.
Many of the agency's
orders, however, state that an unsafe condition
exists. For example, in its order for the 37
767-300s, the agency said: "The FAA has
determined that an unsafe condition exists." The
entertainment systems are connected to an
electrical source "that cannot be deactivated
without also removing power from airplane
systems necessary for safe flight and landing."
Scott Toner, principal
certification engineer for Matsushita Avionics
Systems, the largest in-flight entertainment
system manufacturer, says that could be
interpreted to mean that flights flew with
unsafe systems. "An airworthiness directive may
identify a problem that wasn't recognized when
we designed the system. When the problem's
found, we take care of it," he says.
The in-flight
entertainment industry generated more than $2
billion in revenue in 2000, according to a study
by consultant Frost & Sullivan, but has been
devastated, along with the rest of the airline
business, by a sharp business decline after the
Sept. 11 terrorist attacks.
For financially ailing
airlines, upgrading entertainment systems is not
a top priority, industry executives say.
Northwest, for instance, says its newer jets
include entertainment systems with "new, proven
technology" recommended by aircraft
manufacturers and tested for safety. The airline
says it usually doesn't upgrade the systems
already on older jets.
That the systems raise
safety concerns is contrary to their purpose,
says an entertainment industry expert:
distracting passengers who don't feel safe.
"Airlines still feel the need for in-flight
entertainment to keep people occupied and calm,"
says consultant Rich Salter, who designed a map
passengers use onboard to monitor their flight.
"There are a significant number of nervous
fliers, and an entertainment system can keep
their minds off the flight."
Historically, airlines
have said they equip planes with the systems
because passengers want them. "Most airlines say
their return is in customer satisfaction," says
Brookler. "I haven't heard anyone say the system
pays for itself." But as the systems become more
interactive, airlines can generate more revenue
from advertising, as well as from passengers who
choose to shop, surf the Internet or watch a
pay-per-view movie.
American Airlines equips
its jets with the systems because "customers
expect some in-flight entertainment, especially
on long flights," says spokesman Tim Kincaid. He
says the systems also help American stay
competitive.
But Candace Kolander of
the Association of Flight Attendants union says
the airline industry has become too obsessed
with pleasing passengers. "We may be pushing the
entertainment systems too far and not stepping
back to consider safety," she says.
Certifying the systems
Nick Lacey, an aviation
consultant and a former top FAA official, is
particularly concerned about the FAA's policy of
allowing private companies or individuals to
certify design and installation of entertainment
system retrofits on aircraft. The FAA allows
manufacturers to use their own employees or hire
contractors to certify their products.
"I believe the FAA
process of determining the skills needed for
certifying a modification project has never
worked," says Lacey. "As the program exists now,
it seems to me that a designee can inadvertently
wander beyond his area of competence, or make a
mistake, and it might not be picked up. That is
unacceptable."
In its statement, the FAA
said that its "delegation programs have served
the aviation industry and public well since
1927." The agency said it has set more specific
policies for designee qualification and
oversight.
Some entertainment
company officials say they are increasingly
relying on aircraft manufacturers Boeing and
Airbus for guidance in their systems' design,
installation, type of wiring used and interface
with existing electrical systems on the planes.
Airlines demand such input, they say.
In a written statement,
Boeing says it "establishes the environmental,
electromagnetic, flammability and airplane
interface requirements" that the system
manufacturers must meet. The requirements,
Boeing says, are similar to those required for
critical flight systems.
Airbus spokeswoman Mary
Anne Greczyn says the company has rigorous
standards for entertainment and other aircraft
systems. Airbus provides extra protection on
entertainment system wiring by using sleeves and
other materials, she says.
Lacey believes planes are
safer without the systems. "We could choose to
do without fancy entertainment systems," he
says. "A good book works for me." |
