Accidents & Serious Incidents involving B773

  • 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, 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.)
  • B773, vicinity Melbourne Australia, 2011 (CFIT HF) (On 24 July 2011, a Thai Airways International Boeing 777-300 descended below the safe altitude on a night non-precision approach being flown at Melbourne and then failed to commence the go around instructed by ATC because of this until the instruction had been repeated. The Investigation concluded that the aircraft commander monitoring the automatic approach flown by the First Officer had probably experienced ‘automation surprise’ in respect of the effects of an unexpected FMS mode change and had thereafter failed to monitor the descent of the aircraft with a selected FMS mode which was not normally used for approach.)
