Accidents & Serious Incidents involving B77W

  • A320/B773, Dubai UAE, 2012 (On March 20 2012 a Ural Airlines Airbus A320 failed to taxi as instructed after vacating the landing runway 12L at Dubai and crossed the lit stop bar of an intersection access to runway 12R before stopping just in time to prevent a collision with a Boeing 777-300ER about to pass the intersection at very high speed on take off. Taxi clearance had been correctly given and acknowledged. The aircraft commander had extensive aircraft type experience but the inexperienced First Officer appeared to be undergoing early stage line training with a Safety Pilot present. The Investigation is continuing.)
  • B773, Lagos Nigeria, 2010 (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.)
  • B773, vicinity Toronto Canada, 2012 (On 28 May 2012 a GE90-powered Air Canada Boeing 777-300ER experienced sudden failure of the right engine during the initial climb after take off. There were no indications of associated engine fire and the failed engine was secured, fuel jettisoned and a return to land made. The Investigation found that the failure was related to a known manufacturing defect which was being controlled by repetitive boroscope inspections, the most recent of which was suspected not to have identified deterioration in the affected part of the engine.)
  • C525 / B773, vicinity London City UK, 2009 (On 27 July 2009, a Cessna 525 departing from London City failed to comply with the initial 3000 ft QNH SID Stop altitude and at 4000 ft QNH in day VMC came into close proximity on an almost reciprocal heading with a Boeing 777-300ER. Actual minimum separation was approximately 0.5nm laterally and estimated at between 100 ft and 200 ft vertically.)
