An ANA All Nippon Airways Boeing 787-800, registration JA840A performing flight NH-959 from Tokyo Narita (Japan) to Shanghai (China) with 240 people on board, was accelerating the engines for takeoff from Narita’s runway 34L when the left hand engine (Trent 1000) failed with a loud bang prompting the crew to reject takeoff at low speed (about 20 knots). The aircraft returned to the apron, metal debris reportedly blades from the engine needed to be removed from the runway.
A replacement Boeing 787-800 registration JA815A reached Shanghai with a delay of 3 hours.
