History of the flight |
|
|
1.1.1 |
TF-FIO, a Boeing
757-208 from Icelandair with the call sign of FI-315, was on a
scheduled flight from Keflavik Iceland (BIKF) to ENGM. The
flight departed BIKF 0735 UTC. The flying time to Oslo was
planned to be 2:10 hours. |
|
|
1.1.2 |
The flight was
dispatched with the following equipment inoperative: Right ILS,
right GPS and center autopilot (A/P). |
|
|
1.1.3 |
The take-off and
landing weights were within normal limitations. |
|
|
1.1.4 |
The scheduled
flight was uneventful until the descent and approach to ENGM.
The Commander was the pilot flying (PF) and the First Officer
performed the duties of the non-flying pilot (PNF). The
aircraft was flown by the autopilots (AP). |
|
|
1.1.5 |
At a distance of
approx. 200 NM from ENGM the First Officer received and noted
down the 0920 UTC Automatic Terminal Information Service (ATIS)
for ENGM, which stated RWY 01R was in use and that the weather
was satisfactory for an approach to this RWY. The Commander
planned for a practice CAT II approach. Instruments and
navigation aids were set and the approach was briefed according
to Icelandair Standard Operating Procedures (SOP). |
|
|
1.1.6 |
From ATC, the
crew received descent instructions and SIG 2E arrival. (See
Appendix no. 1: AIP NORGE/NORWAY AD 2 ENGM 4-16 and 4-15.) The
descent was started at time 0930 UTC, approx. 117 NM (track
miles) from ENGM. During the descend TF-FIO was cleared direct
to SONER with free speed below FL 100. Later the crew was
informed that the runway in use at ENGM was changed to runway
01L. The reason for the runway change was snow clearing in
progress on runway 01R. The whole descent and approach was made
in strong tailwind. ATC did not give any information regarding
the wind. The crew was initially aware of the strong tailwind,
but they also knew there was a light northerly wind at the
airport and due to the high workload in the approach they failed
to notice that the tailwind was much stronger than forecasted.
Wind information was available through the flight deck
instrument equipment. Later TF-FIO was cleared direct to Non
Directional Beacon (NDB) Solberg (SLB). (See Appendix no. 2:
AIP NORGE/NORWAY AD 2 ENGM 5-1.) The change of runway, the
strong tail wind and the shortened approach path resulted in the
aircraft becoming high on the approach profile. |
|
|
1.1.7 |
The aircraft was
flown on the autopilot flight director system (AFDS). As the
aircraft was high on the descent profile, the Commander extended
speed brakes at times, trying to maintain proper descent
profile. During the descent the aircraft’s speed was slowed
down to approx. 240 kt. There is no CAT II approach onto RWY
01L and the crew performed a new approach briefing because of
the change of runway. Instrument and navigation aids were
correctly set and identified for a CAT I approach to RWY 01L. |
|
|
1.1.8 |
At distance 10
NM from SLB, the crew of TF-FIO was cleared to descent to 3 000
ft and were told they could expect inbound turn on the localizer
(LLZ) in 8 NM. The aircraft was slowed down to approx. 220 kt
and flaps were extended. Close to overhead the NDB SLB, the
crew received the clearance to intercept the LLZ at time 0945
UTC. Approach mode was selected on the Mode Control Panel
(MCP). The autopilot flight director system captured the LLZ
almost immediately, but the aircraft overshot the centreline.
After crossing the LLZ centreline due to the limitations of the
AFDS, an interception was made from the right side of the LLZ.
The aircraft was at this time above on the Glide Path (GP). The
AFDS corrected to the left to intercept. At 3 000 ft, the
tailwind velocity was approx. 45 kt. The FDR data indicate the
winds at 2 000 ft AGL were not constant, reducing from 30 to 20
kt from an approximate heading of 200o. As altitude
decreased to 500 ft AGL the FDR winds shifted to a heading of
approximately 60o to 70o and decreased to
approximately 8 kt. (On the ground the wind was light from the
north). |
|
|
1.1.9 |
At the time, 0946
UTC, the aircraft was cleared by ATC down to 2 500 ft, and this
altitude was set on the MCP. This setting was maintained
through the aborted approach. The gear was selected down. When
the aircraft finally was established on the LLZ, it was at least
1 dot high on the GP. Flaps 20o had been set with
appropriate speed selection. |
|
|
1.1.10 |
As the Commander
doubted that the AP in AUTO mode could capture the GP, he
disconnected both AP’s and the Auto Throttle (AT) with the
thumb-switches in order to manually capture the GP from above.
The aircraft was flown manually the remainder of the approach,
and the throttles were also operated manually until TOGA was
initiated. Shortly there after, the Commander noticed that raw
data information of the ILS on his ADI and HSI were lost. No
flag warnings were observed. The Commander reduced the rate of
descent because of the uncertaincy. The raw data signals on his
instrument panel appeared and disappeared again. The First
Officer was informed, but on his instruments all indications
were normal. The crew did not consider a change of controls at
this time. |
|
|
1.1.11 |
The aircraft
descended through 1 000 ft AAL (Above Aerodrome Level) in an
unstabilized mode without the mandatory “call out”. |
|
|
1.1.12 |
At an altitude of
approx. 580 ft AAL (Flight Data Recorder (FDR) radio altimeter
reading) the Commander decided that he discontinued the
unstabilized approach and initiated a missed approach. The time
was 09:49:11 UTC. He announced his decision to the First
Officer and started a “Go-Around” (GA). |
|
|
1.1.13 |
The status of the
flight was as follows: The aircraft was above the GP, and the
SOP calls for the GA altitude to be set when stabilized on GP,
therefore the GA altitude was not set on the MCP. Flaps were
not in landing configuration, because landing Check List was not
completed. The Commander’s instrument panel indicated
intermittent ILS failures of raw data without any flag
warnings. The lowest altitude AAL indicated on the FDR was
approx 460 ft. |
|
|
1.1.14 |
The “pitch over”
incident is here described mainly based on the FDR information
with the Commander’s and First Officer’s reports incorporated: |
|
|
1.1.14.1 |
When the go-around manoeuvre was started by the use of
the auto go-around system, the speed was 182 kt. The aircraft
was flown manually. The aircraft pitch was increased to approx.
20o and the aircraft started to climb. Upon
initiating the go-around, the A/T automatically engaged and
increased the thrust to the EPR (Engine Pressure Ratio) limit.
In addition, the application of the under wing engine power also
gave pitch up movement. During the climb the landing gear was
retracted. The flight director pitch initially targeted a pitch
attitude of 15o. The airspeed reached a maximum of
198 kt before it started to decrease. |
|
|
1.1.14.2 |
Because of the
aircrafts proximity to the MCP selected altitude of 2 500 ft
when the go-around was started; the AFDS transitioned to
Altitude Capture almost immediately after a positive rate of
climb was achieved. At time 09:49:19 UTC the aircraft climbed
rapidly through the MCP altitude of 2 500 ft, The FD continued
to give commands targeting the MCP selected altitude. The A/T
changed from go-around mode to targeting the MCP selected speed
(150 kt). The maximum aircraft pitch (21o) was
reached. The thrust remained near maximum because the Commander
held the throttles forward. The speed was decelerating and
quickly dropped below MCP speed. The pitch flight director
continued to give command to lead the pilot back to the MCP
altitude. |
|
|
1.1.14.3 |
At time 09:49:34
UTC the aircraft reached a peak altitude of 2895 ft (FDR QNH
corrected altitude) and the speed had decreased to 137 kt. (The
reference speed for flaps 20o is 131 kt.) Nose down
was applied manually by the control column. The First Officer
called for “bug up” (for the flap up manoeuvring speed) to set
the airspeed indicator, and the Commander pushed on the Flight
Level Change Switch (FLCH) button to break the flight director
altitude lock on. The speed selected on MCP was changed from
150 kt to 210 kt. During the next seconds, a full nose down
input on the control column was made manually. The aircraft
pitched over to an attitude of approx. –30o, and for
a period of approx. 5 seconds the FDR indicates negative
g-values with a maximum load factor of –0.6 g. |
|
|
1.1.14.4 |
The control
column was briefly returned to near neutral, and then another
abrupt large nose down column input was made. The aircraft
pitched over rapidly with the speed increasing excessively. The
FDR data show that the Ground Proximity Warning System (GWPS)
aural warning of “Pull up” was activated. The aircraft was now
in a steep dive and rapidly descending. During the dive the
flight director pitch bar gave pitch up commands relative to the
pitch attitude. The A/T reduced the trust from 98% N1 to 45%
N1. At time 09:49:44 UTC the aircraft pitch attitude had peaked
at -49o and was beginning to increase positively. |
|
|
1.1.14.5 |
At this time the
First Officer called out “PULL UP!” - “PULL UP!”. The GPWS
aural warnings of “TERRAIN” and then “TOO LOW TERRAIN” were
activated. Both pilots were active at the control columns and a
maximum “up” input was made. A split between left and right
elevator was indicated at this time. It appears the split
occurred due to both pilots being active at the controls. The
pilots did not register the aural warnings. During the dive the
airspeed increased to 251 kt and the lowest altitude in the
recovery was 321 ft radio altitude with a peaked load factor of
+3.59 g’s. |
|
|
1.1.14.6 |
The recovery
continued with the aircraft pitch attitude increasing to about
40o, and a positive rate of climb was
established. The AT increased the thrust back to around 98%
N1. Eventually a normal trimmed flight was established, after a
short level off around 3 000 ft, finally at 4 000 ft, after
several abrupt control inputs. |
|
|
1.1.15 |
Reports from the
chief cabin attendant and some of the passengers on the status
during the “pitch-over” can be summarized: |
|
|
|
|
The movement
of the aircraft resulted in water being expelled from
toilets and all loose articles started to move around.
Bags stored from underneath seats became loose,
newspapers moved out of paper racks, magazines and books
out of seat pockets, mobile phones and spectacles were
lifted from pockets of personal clothing. In some
cases, articles belonging to passengers sitting in front
of the wing section ended up in the aft galley.
Fortunately, everybody, with one exception, had their
seatbelts fastened. He did not know whether he had
fastened it or if it had become unfastened. He was in
shock and demonstrated several signs of distress.
The
passengers felt the positive and negative g-forces as
extreme and very uncomfortable. It led to chaos in the
cabin. The manoeuvres were very scaring, some were
screaming and others were praying to God. |
|
|
|
1.1.16 |
When established
at 4 000 ft the appropriate selections were made on the MCP.
The AP was engaged. The First Officer reported the missed
approach to the Approach Control, which gave TF-FIO vectors for
a new approach. No information about the incident was given,
and ATC was not made aware of the abnormal manoeuvre. |
|
|
1.1.17 |
The whole
“pitch-over” manoeuvre was made in clouds. Some of the
passengers had a brief view of the ground when the aircraft was
at the lowest point. For the flight deck crew, the incident
took place in IMC. |
|
|
1.1.18 |
The Commander
gave a short announcement to the passengers and cabin attendants
stating the approach had not been successful. A new approach
had been started, and a landing could be expected within 10
minutes. When established on final the Commanders ILS raw data
disappeared again. He handed over the control of the aircraft
to the First Officer who landed the aircraft at time 1102. |
|
|
1.1.19 |
Because of the
negative and positive load factors, the chaos in the cockpit was
identical to that in the cabin. Flight bags and papers had been
thrown about. During the taxiing-in the pilots made a short
review (debriefing) between themselves of the “pitch-over”
manoeuvre without coming to a conclusion of what really had
happened. |
|
|
1.1.20 |
After parking at
the gate the passengers with destination Oslo left the aircraft
without any orientation/briefing of the missed approach and the
following manoeuvres. The passengers were confused and many
were shocked and frightened. |
|
|
1.1.21 |
When the
aircraft was parked, the pilots cleaned up the cockpit. The
Commander gave a short initial briefing to the cabin
attendants. He requested contact with a technician. The First
Officer had requested through Scandinavian Airlines System
(SAS), the ground-handling agent, a technician to report to the
aircraft. SAS contacted the Braathens airline company and a
technician arrived, informing the Commander that his licence on
B757 had expired, and as far as he knew there were at present no
maintenance contract between Icelandair and Braathens. The
technician also informed the Commander that by contacting
Icelandair the validity of his licence could be extended. This
would probably take some 30 minutes. (A valid contract was in
force between Icelandair and the company Britannia of Sweden
which operates B757’s. However this company did not operate at
Gardermoen airport at the time of the incident. It has later
been confirmed that Britannia technical personnel were available
at the time of the incident.) The Commander was not aware of
this fact. |
|
|
1.1.22 |
At the time the
Braathens’ technician arrived, the Commander was in the
telephone with the Icelandair Maintenance Control at Keflavik.
He informed the company of the failures of the basic ILS data,
the lack of flag warnings, and thereafter handed the phone over
to the technician. In agreement with the Maintenance Control in
Iceland, the Braathens’ technician made BITE tests of the
instrument system. When the tests were completed, he checked
the raw data for normal indications and informed the Commander
about the results. No information of load or speed exceedances
was given to the technician. |
|
|
1.1.23 |
The technician
was finally asked by the Commander to check the flaps
operation. The flaps were extended and retracted. A normal
operation was indicated. |
|
|
1.1.24 |
The Commander
took time to give a thorough briefing of what he thought had
taken place to the stunned cabin attendants. He also asked them
if they wanted to continue onwards on the scheduled flight. All
five of them agreed to continue their duties. |
|
|
1.1.25 |
After a discussion with the First Officer who was
concerned of possible exceedance of maximum flaps 20o
speed, the Commander decided to continue the flight according to
schedule. The First Officer agreed to the continuation of the
flight. The flight crew were not at the time aware of the fact
that the aircraft had been overstressed. Possible exeedances of
load factors were not discussed. When the continuing passengers
for Stockholm boarded, they also received a briefing of the
missed approach and the following “pitch-up”. |
|
|
1.1.26 |
The flight
continued to ESSA and later on to Iceland. The flights were
uneventful, and all systems worked normally. |
|
|
1.1.27 |
During the stop
at ESSA, a phone call to the company chief pilot was made. The
Commander requested a meeting for a debriefing of the aborted
approach at Oslo airport Gardermoen upon arrival Iceland. |
|
|
1.1.28 |
After landing at
Keflavik airport Iceland, the chief pilot of the Icelandair met
the crew of TF-FIO at Reykjavik. Details from the manoeuvring
of the aircraft were given. The FDR was removed from the
aircraft upon order from the chief pilot. |
|
|
1.1.29 |
The aircraft
continued operating until 25th of January when a
C-check was performed. The aircraft was released on the 7th
of February, and was flying on scheduled flights until 13th
of March when the Boeing Company recommended further inspections
after evaluating data of the incident from the FDR. |

Aircraft information |
|
|
1.6.1 |
Boeing 757-208,
registered TF-FIO, is a medium range twin turbofan airliner. It
is powered by two 178,4 kN (40,100 lb st) Rolls-Royce
RB211-535-E4 turbofans. The aircraft was manufactured in 1999. |
|
|
|
The aircraft was
dispatched from Keflavik with the following equipment
inoperative: Right ILS, Right GPS and Center autopilot. These
dispatch deviations were allowed according to the Minimum
Equipment List (MEL) and accepted by the Commander of the
flight. |
|
|
1.6.2 |
In February 2002,
after the incident, the aircraft went through a C-check. When
Boeing became aware of the seriousness of the incident, the
company requested Icelandair to perform a very extensive
structural inspection on the airplane. The inspection was
focused on the fuselage, wings, empennage and the engine strut
connection. The inspection asked to look for distortion, flaked
paint, cracks, and buckled structure and for fasteners that have
pulled out or “are not there”. The inspection was very
detailed, and required many of the inspection tasks that already
had been accomplished during the above-mentioned C-check. The
Boeing Company sent a wing structure engineer specialist to
assist with determining possible damage, and to determine if
further inspection would be required. It turned out that a
re-inspection of the parts that had been inspected during the
C-check was not necessary. As a result of this, the extent of
the inspection decreased. It was apparent that the airplane’s
structure had not been damaged. As a precaution, the following
parts were exchanged: |
|
|
|
|
1. |
Six fuse bolts in the
engine strut connection |
|
2. |
The forward bolts on
the flap track to wing connection |
|
3. |
The two bolts that
run through the two main rollers, on each flap track. |
|
|
|
|
The engine
manufacturer, Rolls Royce, decided after contact with Icelandair
that no special inspection would be necessary on the engines.
Rolls Royce did, however, recommend that the engines mount
connection points should be inspected next time the engines were
removed. |

Aerodrome information |
|
|
1.9.1 |
Oslo airport
Gardermoen (ENGM) is equipped with modern communication- and
navigation equipment. There are several area radio navigation-
and approach-aids. These consists of NDB’s, DME’s and
DME/VOR’s. There are installed ILS to all runways. Runway 01R
has a ILS of CAT II standard, while runway 01L’s ILS is of CAT I
standard. The aerodrome is furnished with both approach- and
ground radar. All aids worked normally at the time of the
incident. |
|
|
|
|
1.10 |
Communications |
|
|
1.10.1 |
The radio
communications between TF-FIO and the different ATC controllers
functioned normally. Judging from the recordings, radio
reception was good and there was no interference on the
frequency. The phraseology used was mainly in accordance with
the instructions. |
|
|
|
|
1.11 |
Flight recorders |
|
|
1.11.1 |
The aircraft was
equipped with a Honeywell flight data recorder, P/N
980-4700-042, S/N 3979. The FDR was removed from the airplane
January 22th 2002. The data has been of great use
for this investigation. |
|
|
1.11.2 |
A cockpit voice
recorder (CVR), type L3 Communication (Fairchild) type
2100-1020-00 was installed. As the flight continued after the

The airline |
|
|
1.17.1.1 |
Icelandair as an
airline traces its roots to the year 1937 when a fledging
airline, Flugfelag Akureyrar, was founded at Akureyri on the
north coast of Iceland. In 1943 the company moved its
headquarters to the capital city, Reykjavik, and changed its
name to Flufelag Íslands. The airline later assumed the
international trade name of Icelandair. |
|
|
1.17.1.2 |
Another important
milestone was passed in 1944, when three young Icelandic pilots,
returning from their flight training in Canada, founded
Loftleidir, which later became known as Icelandic Airlines.
Initially both companies concentrated on Icelandic domestic air
services. However, in 1945 Flugfelag Íslands made its first
international flights to Scotland and Denmark. Loftleidir
started international operations in 1947. It’s pioneering
low-fare services across the North-Atlantic commenced in 1953. |
|
|
1.17.1.3 |
In 1973 it was
agreed to merge Flugfelag Íslands and Loftleidir under a new
holding company, Flugleidir. In October 1979 Flugleidir assumed
all operating responsibilities of its two “parents”, and decided
to use Icelandair as its international trade name, only
retaining the Flugleidir name in the Icelandic domestic market. |
|
|
1.17.1.4 |
The company is
100% privately owned by 4517 Icelandic shareholders. It is the
largest private company in Iceland, employing over 2 000 people. |
|
|
1.17.1.5 |
Icelandair has been a member of IATA (International Air
Transport Association) since 1950, a member of AEA (Association
of European Airlines) since 1957, and a member of the Flight
Safety Foundation since 1966. |
|
|
1.17.2 |
Organization |
|
|
1.17.2.1 |
Icelandair operated scheduled passenger, cargo and
charter flights primarily between Iceland, Europe and North
America. It is one of the largest aviation operators in Iceland
and has a long and distinguished operational record. In 1990
the airline started to expand and restructure its aircraft
fleet. It is presently operating a fleet of 11 Boeing 757-200
and 757-300 aircraft. |
|
|
1.17.2.2 |
Authority for
operation is by an Air Operators Certificate (AOC) issued by the
CAA of Iceland. Iceland is a member of the JOINT AVIATION
AUTHORITIES, and Icelandair operates according to JAR-OPS 1
requirements. |
|
|
1.17.2.3 |
An Accountable
Manager has the overall responsibility for all aspects of
aircraft operation and Nominated Post Holders are responsible
for: |
|
|
|
- |
Flight Operation |
- |
Maintenance Systems |
- |
Crew training |
- |
Ground Operations |
|
|
|
|
At the time of
the incident one person is Nominated Post Holder for Flight
Operation, Crew Training and Ground Operation. |
|
One other person
is Nominated Post Holder for Maintenance Systems. |
|
|
1.17.2.4 |
A comprehensive
Flight Operations Manual (FOM), supplemented by Aeroplane
Operating Manual (AOM), Route Manual (RM) and Training Manual
(TM) controls the different aspects of Flight Operations. A
Manual System described by a “manual tree” places the different
manuals in relation to each other. |
|
|
1.17.2.5 |
Crew selection, initial technical- and flight training
and recurrent training satisfy the requirements from the
authorities. The training is organized in a series of modules
given at different times and at different locations. Crew
Resource Management (CRM) is one such module. The modular
system places increased workload on Flight Operations
management in the areas of checking and supervision in order to
assure that all safety critical items and procedures are
adequately addressed. The new training facility in Reykjavik
was opened in December 2001 before the incident occurred. After
the incident Icelandair has started using the new in-house
training facility utilizing the latest state-of-the-art training
aids. |
|
|
1.17.2.6 |
Icelandair was
not at the time of the incident utilizing a systematic analysis
of flight recorder data of all flights for supervision, control
and monitoring of the company’s operational standard. The
present aircraft fleet is equipped with Quick Access Recorders
making such analysis possible. |
|
|
1.17.2.7 |
Icelandair has a
philosophy and a set of policies as well as procedures and
practices in order to maximize the safety of all flights. |
|
|
1.17.3 |
Training and
selection |
|
|
1.17.3.1 |
In order to be
accepted as a pilot candidate for Icelandair, the flying
experience required is either: |
|
|
|
1) |
having previously received type rating on an
aircraft requiring two pilots or |
2) |
having
accumulated at least 1 500 flight hours, or |
3) |
having
accumulated at least 500 flight hours and completed
specific training courses approved by ICAA in
preparation for training on turbo-jet airplanes. |
|
|
|
1.17.3.2 |
The pilot
candidates to Icelandair must in addition pass an extensive
selection process before being accepted for pilot training in
the company. |
|
|
1.17.3.3 |
The candidates
have to undergo several psychological tests like MMPI (Minnesota
Multiphasic Personality Inventory). (MMPI is a method for
measurement of traits of personality, such as those having to do
with interests, attitudes, emotional adjustment and social
relations, all-important aspects of a pilot’s personality and
abilities). In addition the pilot candidates are checked for
psycho-technical abilities, communication skills, leadership
potential, stress tolerance and inductive intelligence. Further
the candidates have to demonstrate basic flying and CRM (in this
connection Cockpit Resource Management) skills in a
flight-training device where two applicants are tested at the
same time. |
|
|
1.17.3.4 |
Being accepted as
a pilot in Icelandair the pilots undergo an initial course
including type rating, and a four weeks ground course followed
by two weeks of simulator training. Finally landing and line
flying under supervision is given for 1 – 3 weeks. Both flight
crewmembers had undergone this flight training. |

2. |
Analysis |
|
|
2.1 |
The descent and the unstabilized approach: |
|
|
2.1.1 |
The descent was
started at normal time and distance from the planned landing
runway. After the descent had been initiated, there was a
change of runway; but this made only a minor shortening of the
distance. Later the descent distance was shortened twice by
ATC. This, together with the strong tailwind, caused the
aircraft to become high on the approach profile. Contributing
to this incident was also the air traffic controller’s vectoring
of the airplane. To compensate, the Commander was using speed
brakes. In spite of this, the aircraft was still high when
approaching the point of the glide path capture for runway 01L.
The Commander did not contact ATC in order to extend the descent
distance. To get rid of the high energy of the aircraft became
a problem. A stabilized approach is critical for a safe
landing. Everyone involved in the system has an important role
to play. When the last turns were made to intercept the LLZ,
they were made too late with the result that the aircraft
overshot. A new intercept from the opposite side had to be
made. During the hearing of this report AAIB/N received the
following from CAA Iceland: |
|
|
|
“We think that
there should be more emphasis on the captains responsibility to
plan his approach in such a way that a stable approach can be
made, to follow standard operating procedures and to follow and
see to it that CRM procedures are followed. If the captain
fails in his duties, the first officer should of course draw the
captains attention to the irregularity.” |
|
|
|
AAIB/N
are in agreement with this statement. |
|
|
2.1.2 |
When, finally,
the aircraft was stabilized on the LLZ, it was high on the glide
path, the correct flap setting was not made, and the approach
speed was varying, being too high. The final landing checklist
could not be completed according to SOP, as the completion of
this checklist depended on being stabilized on the glide path.
The Commander analysed the situation during the continued
approach, and finally, when he also lost raw data from the ILS
on his instruments, he correctly decided – late in the sequence
- to abandon the approach and to perform a go-around. |
|
|
2.1.3 |
AAIB/N consider
that the Commander entered into a situation of mental overload.
The overload started when he did not comprehend the problem
being high on the descent profile. The aircraft ended being
unstabilized on the final approach. According to SOP, the
aircraft should be in landing configuration and only very small
corrections to speed, power and attitude should be rendered at
this final stage of approach. |
|
|
2.1.4 |
In an approach in
marginal weather, there should normally be a high degree of
cooperation between the crewmembers. AAIB/N have reached the
opinion that sufficient cooperation did not take place. The SOP
and the flight crew training, especially the CRM-training,
should have lead to a more active crew cooperation. The
hesitant attitude of the First Officer during the approach is
considered an important factor for the unstabilized approach and
the Commander’s mental overload situation. It is of no less
importance the obligation of the Commander to remind the
Co-pilot of his duties as Pilot Not Flying. The lack of
call-outs regarding altitudes and speeds reinforced the
difficult situation that eventually developed. The decent and
approach were not performed according to the company SOP. |
|
|
|
|
2.2 |
The go-around: |
|
|
2.2.1 |
It is difficult
to fully understand why the crew unintentionally entered the
extreme manoeuvres following the abortion of the approach. This
part of the flight was performed in IMC. In trying to
understand why it happened, it is necessary to look into details
of the “upset”. |
|
|
2.2.2 |
When the
Commander finally, too late in the sequence in the opinion of
AAIB/N, decided to discontinue the unstabilized approach, he was
flying the aircraft manually. When initiating the auto
“Go-around”, the auto throttle became engaged, and increased
automatically the engine trust to the EPR limit. The
application of the under wing engine power also gave a pitch up
movement. The flight director pitch bar commanded a pitch
attitude of 15o. (The AFDS commanded a level off at
2 500 ft (the last assigned altitude by ATC). The AFDS
calculates the high closure rate to 2 500 ft and captures
that altitude almost immediately; causing the A/T to change from
Go-around mode to retard power to MCP selected speed (150 kt)).
The aircraft therefore climbed very rapidly through the MCP
selected altitude of 2 500 ft and with the aircraft pitch
increasing to 21o. AAIB/N considers that the
Commander at this time had lost situational awareness (being
“behind the aircraft”). |
|
|
2.2.3 |
As the Commander
noticed the speed to be rapidly decreasing, he pushed the
control column forward. This was in order to follow the command
of level off at 2 500 ft. Pushing the control column forward is
also an elementary flying procedure to increase the speed and to
prevent the aircraft from entering a stall. |
|
|
2.2.4 |
The First Officer
at this time called for “Bug up”. The Commander reached for and
resat the MCP speed. This was contrary to company Standard
Operation Procedure. Simultaneously the Commander continued to
push the control column even more forward. The aircraft reached
a maximum altitude of 2 895 ft and the load factor reached a
negative g-value of –0.6. |
|
|
2.2.5 |
The aircraft then
entered a rapid dive, and the speed increased. Different
warnings were given of ground proximity and the command of pull
up by the aircraft systems, but not registered by the crew. The
A/T reduced the trust from 98% N1 (full power) to 45% N1 (idle
power). The negative pitch reached a maximum value nose down of
49o. Up to this time the First Officer had been
somewhat passive and confused. Now he acted as an active and
co-operative crew member and asked: “What are you doing” and
next, he called out: “Pull up!” - “Pull up!”. Both pilots
pulled back on their control columns, and the aircraft, after
reaching a maximum speed of 251 kt, recovered from the dive with
a clearance of 321 ft (radio height) over the north end of the
runway 01L. During the pull-up the load factor increased to
positive G-value of 3.59. |
|
|
|
To the
hearing of this report the Commander gave AAIB/N the following
statement: |
|
|
|
“I
believe my First Officer acted as an active and co-operative
crewmember throughout the flight, but in the final approach, due
to the abnormally high workload, both of us became occupied
handling details instead of looking at the whole picture. And
when we suddenly got the altitude capture commands from our FDS,
when both of us were mindset for a go-around, we became confused
and later on the unbelievable nose down pitch attitude, we
became even more confused.” |
|
|
2.2.6 |
The aircraft
pitch then increased to about 40o nose up, and after
several abrupt control inputs, the aircraft was levelled off at
4 000 ft. Pitch upsets are defined as pitch in excess of 25o
up and 10o down. As the pitch values were outside
these limits, the artificial horizon indication became all brown
as registered by the Commander when the aircraft descended.
This baffled the Commander even more. (There is at least 0.25
inches of blue visible on the HSI during this situation on the
accident airplane as delivered.) |
|
|
2.2.7 |
The importance of
crew cooperation is imperative. In this case, AAIB/N is of the
opinion there was a complete breakdown of crew management and a
lack of interaction at an early stage. When the confusion
started, the combination of one pilot manually operating the
controls partly in opposition to the automatic throttle movement
made this “upset” understandable. This can be referred to as an
“automation trap”. When “bug-up” is selected to target speed,
this command gets cancelled by selection of “Flight Level
Change” or by altitude capture. The speed then becomes “present
speed”. This caused the aircraft to act differently than the
pilots had anticipated. This resulted in confusion and was
probably a factor in causing the incident to occur. In the
opinion of AAIB/N it is not satisfactory that a seemingly
properly trained and qualified airline crew should end up
loosing control of a modern airliner and cause an incident like
this one. |
|
|
|
|
2.3 |
Background - training |
|
|
2.3.1 |
Selection of
individual crewmembers, initial training, type training and
recurrent training in Icelandair confirms to the traditional
pattern found in most airlines. The training is organized in
modules and subcontractors may present the different modules
individually in different locations. Each module in itself can
be fully satisfactory as far as contents and presentation is
concerned, but the challenge for the airlines operational
management is to assure that the total training program, with
all its interfaces, fulfils the goal of the operator as well as
the requirements of the aviation authorities. A Quality
Assurance System with the necessary oversight- and supervision
systems are required to monitor the complete training process to
detect possible “glitches” in the interfaces between modules in
order to prevent latent failures in the system. |
|
|
2.3.2 |
CRM training
could be used as an integration tool in order to identify
problem areas and at the same time prepare crewmembers for
better cooperation when handling unusual and unexpected
occurrences during flight. |
|
|
2.3.3 |
A system
utilizing Flight Recorder Data for continuous monitoring of the
flight operational standard and the effectiveness of company
procedures and regulations were not in use in Icelandair at the
time of the incident. Such a system, based on data from the QAR
(Quick Access Recorder), and used to collect statistical data,
has been found by many operators to give valuable early warnings
about problems not easily detected by other means. The
technical equipment needed for the collection of such data is
already installed in Icelandair's Boeing 757 fleet. |
|
|
|
|
2.4 |
Crew Resource Management (CRM) |
|
|
2.4.1 |
CRM training is
required for JAR OPS 1 operations. The application of CRM
concepts can approve crew performance through enhanced
communication training, problem solving, decision-making and
workload management. In the present situation the crew
demonstrated omission of action: ie. insufficient approach
briefings, failure to administer high workload and a lack of
risk assessment - recognize failure from standard procedures.
Failures in CRM may be associated with complacency or
overconfidence. |
|
|
2.4.1.1 |
An important part
of pilot training today is CRM training. CRM is not a universal
recipe for safety, but a highly effective and essential aspect
of flight crew training. CRM has passed through a number of
generations during its lifetime of less than 20 years. The
original CRM was a response to human errors, especially those
associated with ineffective teamwork and decision-making. The
fifth generation is based on the fact that there will always be
human errors and that they are inevitable. To be effective, the
training must therefore credibly communicate the limits of human
factor performance with regard to mental capacity to function
under stress, and thus make the crew more aware of personal
limits and capabilities. |
|
|
2.4.1.2 |
In addition the
effect of CRM training is dependent of different cultures under
which it is performed. In Icelandair one would presume that all
the crew have the same national culture thus simplifying many
aspects of the training. However, one must realise that crew
behaviour is shaped by three additional cultures: professional
culture, organizational culture and the company’s safety
culture. |
|
|
2.4.1.3 |
Professional
culture reflects the attitudes and values associated with an
occupation. For pilots this often means unrealistic denial of
vulnerability to the multiple stressors of the occupation. Such
attitudes may reduce the acceptance of CRM training. Further we
have organizational culture, which is manifested in the openness
between management and employees or in the attitudes and
behaviour of critical role models such as air check men.
Finally a negative organizational culture can result in CRM
being viewed as yet another square filling exercise rather than
the reflection of the organizations standards. |
|
|
2.4.1.4 |
Last but not
least will the company’s safety culture be manifested in knowing
channels to communicate safety concerns and a sense that these
should be addressed. It is essential that training and
evaluation not only focus on the avoidance of error, but also on
the management of error. In accordance with this view the last
generation of CRM training is trying to get rid of the term
“pilot flying and pilot not flying” and substitute it with
“pilot flying and pilot monitoring”. In the present situation
the crew did not function as a crew, but rather as two
individuals in the same cockpit without a common plan for the
flight and landing. The CRM training they had received prior to
the incident had not been integrated in their behaviour the way
it was supposed to: ”CRM is the utilization of all available
resources to achieve safe and efficient operation to enhance the
communication and the management skills of the flight crewmember
concerned”. Lack of planning left the pilots in a stressed
state where they no longer were able to communicate their doubts
or actions. Rather than hiding errors or shortcomings, the open
sharing of error and the effective management of error provide
reinforcement of CRM practice. |
|
|
2.4.1.5 |
Lack of joint CRM training with the rest of the crew was
obvious in the way the crew managed the situation immediately
after landing: It took some minutes before the cabin crew got
any information from the cockpit about the incident, therefore
they were not able to inform the passengers properly about the
situation or make sure the passengers got a psychological
debriefing immediately after leaving the plane. The way the
situation was handled gave the passengers unnecessary problems,
which may take them some time to solve. |
|
|
2.4.2 |
Icelandair should
consider its plans for a colleague support program in connection
with accidents and incidents. Such programs have proven to be
helpful to pilots and cabin attendants after stressful
situations, reducing the time away from active duty and fewer
reports on delayed emotional reactions caused by stressful
experiences. |
|
|
|
|
2.5 |
Organization and management |
|
|
2.5.1 |
Icelandair is
organized and managed in accordance with the requirements of
JAR-OPS 1 and the Icelandic CAA. Rapid expansion and recent
re-organization has resulted in “growing pains” in the
organization. And the management, being aware of the situation,
is monitoring the process closely. |
|
|
2.5.2 |
An investigation
of Icelandair’s Organization and Management along the vertical
line: Philosophies, Policies, Procedures, Practices and along
the horizontal line of the modules: Crew Recruitment, Initial
Training, Technical Training, Flight Training, CRM training,
Commanders Training and Recurrent Training demonstrated certain
weak points: Philosophies and policies were not sufficiently
documented in the manuals to assure that all personnel respond
in the required and correct manner during operation of aircraft. |
|
|
2.5.3 |
Icelandair has a
philosophy and a set of policies as well as procedures and
practices in order to maximize the safety of all flights. A
more clear documentation of the philosophy and the policies in
the different manuals would be of advantage to personnel at all
levels of the Company. |
|
|
|
|
2.6 |
Dispatch of aircraft from Keflavik with inoperative equipment |
|
|
|
AAIB/N is of the
opinion that the inoperative equipment according to MEL: Right
ILS, right GPS and center autopilot did not in any way affect
the operation or performance of the aircraft with regard to the
incident over Gardermoen airport. However, the inoperative
equipment may have been a distracting factor for the Commander. |
|
|
|
|
2.7 |
The Commander’s analysing of the situation after landing
ENGM, and his decision to continue the flight |
|
|
2.7.1 |
After the parking
of the aircraft, the crew became organized. They had been
overwhelmed, stunned and surprised of what had taken place.
Between them they discussed the incident. They were not aware
of the problems with the high load factors. The crew did not
register these values. But they were concerned about a possible
exceedence of airspeed limits. However, they were not aware of
the gross exceedence that had taken place. |
|
|
2.7.2 |
The Commander’s
primary concern was the failure of the basic ILS data, and when
this was remedied by the BITE test, the remaining problem was
the overspeed. When the technician could confirm normal
operation of the flaps, the Commander decided in co-operation
with the First Officer, that the flight could proceed according
to schedule. AAIB/N is of the opinion there should be clear,
updated instructions available for the Commander whom to contact
at an outside station in case of technical problems. AAIB/N
questions the Commander’s decision to continue the flight
without a more thorough inspection made on the aircraft.
Detailed information of the serious incident should have been
given to a responsible operative leader i.e. chief pilot or
operational manager before the flight was continued to
Stockholm. |
|
|
|
|
2.8 |
The situation in cabin |
|
|
2.8.1 |
It is the opinion
of AAIB/N that cabin crew and passengers could have been better
taken care of. It is understandable that the lack of time and
the technical problems present put a heavy load on the
Commander. It is also possible that he was not aware of the
strain they had been through. According to cabin- and passenger
reports the situation in the cabin was rather dramatic. The
heavy positive and negative load factors together with the loose
items being thrown around in the cabin were for them a scaring
experience. Many passengers have fear of flying. An incident
as this one increases the fear and uncertainty for such
passengers. A quick debriefing before the departing passengers
left the aircraft would have been a great relief for the
concerned passengers. According to letters AAIB/N has received,
many of them were scared and as they didn’t receive any
information from the crew or from station personnel after
disembarkation, it has taken a long time for some of these
passengers to treat the personal problems related to this
flight. The company should consider reviewing its procedures of
informing the passengers after unwanted occurrences. |
|
|
|
|
2.9 |
The crew
procedures/performance in relation to Standard Operating
Procedures (SOP) |
|
|
|
The SOP covers in
detail the handling of the aircraft in normal and abnormal
situations. AAIB/N is of the opinion that had the company’s
basic procedures been adhered to by the crew, this incident
would not have happened. Thus the planning of the final stage
of this flight in marginal weather was not thorough enough. The
Commander let the flight become unstabilised in speed and
attitude. Correct call-outs were not made. A detailed plan for
a possible go-around was not made. The final check list could
not be completed since the final flap setting had not been
made. The approach was aborted late on final in spite of the
flight not being stabilized in correct configuration in IMC at 1
000 ft AAL. It is possible that the airport’s relatively high
elevation may have been of importance in this case. Most of the
airports which are used by Icelandair crew are situated at or
close to sea level. Gardermoen’s elevation is 681 ft. When
finally the go-around was started, the Commander let the
airplane fly away from him, and the crew cooperation broke
down. All these details are covered in the SOP. |

safety RECOMMENDATIONS |
|
|
|
AAIB/N
recommends: |
|
|
4.1.1 |
That the aviation
community should review the operational procedure regarding
discontinued approaches. The company should also review the
flight crew training regarding an unstabilized approach followed
by a go-around (Recommendation no 4/2003). |
|
|
4.1.2 |
That the company
should consider its plans for colleague support in relation to
accident and incidents (Recommendation no 5/2003). |
|
|
4.1.3 |
That the company
should consider utilizing the quick access recorders for
continuous monitoring of flight operations standards
(Recommendation no 6/2003). |
|
|
4.1.4 |
That CAA/N should
consider the effect of ATC shortening the approaches in IMC for
airline-crew with possible limited experience of the Oslo area,
and the effect it has on the crew’s ability to manage the
aircraft energy and to stabilize the approach (Recommendation no
7/2003). |
