B773, Lagos Nigeria, 2010

Summary

On 11 Jan 2010, an Air France Boeing 777-300ER successfully rejected a night take off from Lagos from significantly above V1 when control column pressure at rotation was perceived as abnormal. The root and secondary causes of the incident were found to be the failure of the Captain to arm the A/T during flight deck preparation and his inappropriate response to this on the take off roll. It was considered that his performance may have being an indirect consequence of his decision to take a 40 minute period of in-seat rest during the 90 minute transit stop at Lagos.

Description

On 11 Jan 2010, a Boeing 777-300ER being operated by Air France on a scheduled passenger flight from Lagos Nigeria to Paris CDG rejected the night take off on runway 36L at Lagos being carried out in normal night visibility from significantly above the applicable V1 speed when it was perceived that the control column pressure to achieve rotation was abnormal. The aircraft stopped before the end of the runway and after requesting and receiving Rescue and Fire Fighting Services cover in case of brake unit overheating, was taxied to the gate for normal passenger disembarkation. Five main landing gear tyres deflated due to thermal fuse activation approaching or at the gate. None of the 234 occupants were injured and the only aircraft damage was to the wheels and brakes.
