Description

On 14 June 2010, a Boeing 777-200 being operated by British Airways on a scheduled passenger se]]rvice from Singapore to London Heathrow with a relief crew present on the flight received indications of abnormal functioning of the right engine during a night take off in Visual Meteorological Conditions (VMC). Subsequent and directly related developments en route, including greater than planned fuel consumption which put the intended destination out of reach, led to the declaration of a PAN to ATC and diversion to Amsterdam. Inspection after flight found that parts of the right engine were damaged or missing and the latter were matched to previously unidentified debris recovered from the runway at Singapore. None of the 214 occupants were injured.

Investigation

An Investigation was carried out by the UK AAIB. It was noted that the aircraft commander had been PF for the departure and that one of the two augmenting crew members had been present in the flight deck for take off. At approximately 500 feet aal after take off, there was a fluctuation in the N1 indication for the right engine and related EICAS cautionary and advisory annunciations. No immediate action was prescribed and when thrust was reduced to climb setting at acceleration altitude, parameter indications for both engines settled in their normal range. Subsequent system interrogation and thrust lever movement checks did not indicate anything of undue concern and it was decided that the flight should be continued.
