Accidents & Serious Incidents involving B773

  • A320/B773, Dubai UAE, 2012 (RI HF) (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 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, Auckland Airport New Zealand, 2007 (RE HF) (On 22 March 2007, an Emirates Boeing 777-300ER, started its take-off on runway 05 Right at Auckland International Airport bound for Sydney. The pilots misunderstood that the runway length had been reduced during a period of runway works and started their take-off with less engine thrust and flap than were required. During the take-off they saw work vehicles in the distance on the runway and, realising something was amiss, immediately applied full engine thrust and got airborne within the available runway length and cleared the work vehicles by about 28 metres.)
  • B773, En-route, Bay of Bengal, 2011 (LOC WX HF) (On 18 October 2011, an Etihad Boeing 777-300 encountered severe turbulence westbound over the Bay of Bengal because of a late track deviation whilst the aircraft commander was briefly absent from the flight deck. Two occupants, one a member of the cabin crew and the other a passenger, sustained severe injuries and 12 other occupants sustained minor injuries. The subsequent Investigation noted that the severe weather encountered was evident well in advance and could have been avoided. The low level of experience in role and on aircraft type of the operating crew was noted.)
  • B773, Lagos Nigeria, 2010 (RE HF) (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, en-route, South China Sea Vietnam 2011 (LOC WX HF) (On 17 October 2011, a Singapore Airlines Boeing 777-300 in the cruise at night with a Training Captain in command made what turned out to be an insufficient deviation around a potential source of turbulence and, with the seat belt signs remaining off, a number of cabin crew and passenger injuries were sustained during sudden brief but severe turbulence encounter. The Operator subsequently introduced enhanced pilot training to support more effective weather avoidance and better use of the various types of weather radar fitted to aircraft in their 777 fleet.)
