A320, São Paulo Congonhas Brazil, 2007
A320, São Paulo Congonhas Brazil, 2007
On 17 July 2007, the commander of a TAM Airlines Airbus A320 being operated with one thrust reverser locked out was unable to stop the aircraft leaving the landing runway at Congonhas at speed and it hit buildings and was destroyed by the impact and fire which followed killing all on board and others on the ground. The investigation attributed the accident to pilot failure to realise that the thrust lever of the engine with the locked out reverser was above idle, which by design then prevented both the deployment of ground spoilers and the activation of the pre-selected autobrake.
Description
On 17 July 2007, an Airbus A320 (PR-MBK) being operated by TAM Airlines on a scheduled domestic passenger flight (JJ3054) from Porto Alegre to São Paulo Congonhas and making a night landing in normal ground visibility failed to decelerate normally after touchdown on runway 35L and departed the side of the paved surface near its end and became briefly airborne from the elevated terrain before crashing into a building beyond the airport perimeter. Both the building and the aircraft were destroyed by the impact and a fierce fire which followed and all 187 occupants and 12 people on the ground were killed.
Investigation
An Investigation was carried out by CENIPA, the Brazilian Aeronautical Accidents Investigation and Prevention Centre. Data from the SSFDR and 30 minute SSCVR was successfully downloaded and provided important evidence to assist the Investigation.
It was found that both pilots were experienced but that the Co-pilot, a former flight engineer who had recently been recruited by TAM as a Captain had recently completed his A320 type conversion with TAM and had only 237 hours experience on the aircraft type. At the time of the accident, a shortage of co pilots had led to him being cleared for co pilot duties only.
It was established that four days prior to the accident, the aircraft had been released to service in accordance with the applicable Minimum Equipment List (MEL) with the number 2 engine reverser de-activated. It was noted that on the accident flight, it was tankering fuel uplifted at Porto Alegre.
The airport at Congonhas, stated to have been the busiest international airport in Brazil at the time of the accident, is situated in an elevated position in the centre of São Paulo. It had two asphalt runways, the main runway, 17R/35L, which was at the time 1945 metres long and the auxiliary runway, 17L/35R, which was at the time 1435 metres long. Earlier landing aircraft on the day of the accident had advised the TWR that the active runway, 35L, was “wet and slippery”. At the time of the accident, neither runway had a Runway End Safety Area, the provision of which was an ICAO Standard under Annex 14. This situation had not been notified to ICAO in accordance with the article 38 of the Chicago Convention on International Civil Aviation.
Meteorological Terminal Air Report (METAR) and SPECI reports for Congonhas timed shortly before and just after the accident indicated that light rain had been falling, the lowest cloud had been between 800 feet aal and1600 feet aal with visibility between 6km and 8km and the surface wind from between 320º and 350º at 8-12 knots.
The en route part of the flight and the approach to runway 35L at destination were uneventful. Shortly after the aircraft passed 20 feet agl, the CVR recorded the occurrence of the “RETARD” auto callout three times. At this time, the DFDR recorded the left engine thrust lever moving to "IDLE" whilst the right engine thrust lever remained at the ‘CL’ (MAX CLIMB) position - a thrust lever angle position of 25° ahead of ‘IDLE’.
After touchdown at 142 KCAS, the left engine thrust lever was moved to the “REV” position but the right engine thrust lever remained in same position as previously. FDR readings of the EPR were found to correspond to those which would be expected for the recorded thrust lever positions for both engines. Three seconds after the nose landing gear touched down on the runway, there was a sudden yaw to the left which would have corresponded to the selection of the left engine thrust lever to reverse. The Co-pilot confirmed the activation of the left engine reverser and also called the non-deployment of the ground spoilers.
The failure of the ground spoilers to deploy was recorded on the FDR as was the non-activation of the armed autobrakes, which it was noted was a direct consequence of the absence of ground spoiler deployment which alone would have reduced aircraft braking performance by almost 50%. In response to the failure to decelerate, both pilots applied and held maximum manual brake pressure but the rate of deceleration did not improve and was still recorded as almost 100 knots at the final impact of the aircraft with the building below the end of the runway.
Downloaded FDR data did not provide any evidence that aquaplaning had occurred although the Investigation considered that there was “a high probability that the pilots were led to believe that the lack of the expected deceleration after landing was a result of… the wet runway” even though it was apparent that they were aware almost immediately that the ground spoilers had not deployed.
Since the ‘RETARD’ auto callout had sounded after the left hand thrust lever was moved to the flight idle position during the flare to land (because the A/T was still engaged and the right hand thrust lever was in the CL position), it was considered that there was a ‘high probability’ that during the landing, the aircraft commander had “inadvertently” left the right hand thrust lever in the CL position whilst placing the left hand thrust lever initially at flight idle and then into reverse.
It was calculated that landing with an inoperative reverser on a wet runway with one thrust lever in ‘REV’ and the other in ‘CL’ even without considering the thrust provided by the No 2 engine, in excess of 2000 metres would have been necessary for the aircraft to come to a complete stop, In effect, once the aircraft had touched down with no ground spoiler deployment on such a relatively short runway, the excursion off the runway at speed rapidly became inevitable.
Having concluded that the lack of deceleration which led to the overrun had been a consequence of the pilots’ failure to notice that the right engine thrust lever was in the ‘CLIMB’ detent, it was also found that:
- The broader context for the accident was the consequences of the rapid growth of the Operator, TAM, which had “accentuated the effects of the lack of coordination among its diverse sectors, hindering the oversight at all management levels”.
- Because the A320 Service Bulletin (SB) which brought the Flight Warning Computer (FWC) up to the ‘H2F3’ production standard for new aircraft by introducing an ‘ENG X THR LEVER ABV IDLE’ message on the Electronic Centralized Aircraft Monitor (ECAM) if either thrust lever was above ‘IDLE’ during the landing roll was not made mandatory by the Regulator, TAM were not required to adopt it and they did not do so voluntarily.
Potential Contributing Factors, defined in accordance local practice as “a condition (act or fact, or a combination of the two) which, together with other ones, in sequence or as a consequence, leads to or allows the occurrence of an aeronautical accident….or which contributes to the aggravation of its consequences” were considered and categorised as either ‘Human Factors’ or ‘Material Factors’. Those factors “whose contribution was effectively established, regardless of the degree at which such contribution occurred” were identified as such and other factors “whose contribution, however possible, was not confirmed” were categorised as “undetermined”. This distinction was qualified by the statement that such categorisation reflects only the ability “to confirm, with a reasonable degree of certainty, the presence of such factors among the actions and/or conditions which preceded the accident, and (it does) not imply the assignment of values or degrees of importance to any of them”.
The ten factors determined to be contributing were as follows:
- Pilot Training - the means to theoretical qualification for pilots at TAM relied exclusively on CBT but the quality of this training was not assured In addition, the training of the SIC pilot was restricted to “Right Seat Certification”, something that proved insufficient for him to deal with the critical situation experienced after the landing.
- Cockpit coordination - the monitoring of the flight at the landing was not appropriate, since the crew did not have perception of what was happening in the moments that preceded the impact. This loss of situational awareness hindered the adoption of an efficient and timely corrective action.
- Management planning - the situation at TAM during rapid expansion was unsatisfactory. At the time of the accident, the operator had a disproportional number of Captains in comparison with the number of Co-pilots, a fact that obliged the scheduling sector to form crews with two Captains. Thus, although complying with the minimum regulatory requirement, such a practice may have contributed to the creation of a climate of complacency in the cockpit.
- Low relevant experience of the Co-pilot - despite his long experience in commercial jets, the Co-pilot had only about 200 flight hours in aircraft of the A-320 type. Also, his experience in the function of co-pilot was restricted to the “Right Seat Certification” training received.
- Management oversight - TAM routinely allowed the crew to be composed of two Captains, with the occupant of the right-hand seat having done only “Right Seat Certification” training. Besides, the lack of coordination between the several sectors of the company, especially between the sectors of operation and training, determined the lack of an appropriate monitoring of the processes and of the quality of the pilots’ professional training.
- Perception error - although perceiving that the ground spoilers had not deflected, the pilots were not able to associate the non-deflection with the positioning of the thrust levers. In addition, there is a high probability that the pilots were led to believe that the lack of the expected deceleration after landing was a result of the conditions of operation with a wet runway
- Lack of perception - considering the hypothesis of a failure in the thrust control system, the contingent stimulus generated from the loss of resistance to the movement of the thrust levers may not have been perceived by the pilot(s).
- Loss of situational awareness - emerged as a result of the very lack of perception on the part of the pilots. In this respect, the automation of the aircraft, however complex, was not capable of providing the pilots with sufficiently clear and accurate stimuli, to the point of supporting their understanding of what was happening in the moments just after the landing.
- Regulation - although having already considered the availability of reversers as a requirement for operations at Congonhas since at least since April 2006, the Regulator only formalised this after the accident had occurred.
- Design - there was no pilot alerting for the case of one thrust lever in the ‘REV’ position and the other at ‘CL’.
