(ANA) has concluded there was no engine failure following a Jan. 17 incident in which both engines on a Boeing 787-8 shut down after it landed at Japan’s Osaka International Airport.
ANA flight NH985 was arriving from Tokyo Haneda Airport with 109 passengers and nine crew members on board. After touching down on the runway and deploying the thrust reversers to slow the aircraft, pilots noticed that both Rolls-Royce
Trent 1000 engines had shut down. The 787 completed rolling out and came to a stop about 8,000 ft. down the runway, according to media reports.
The carrier said it conducted a thorough investigation of the aircraft and found no engine failure. It did not assign responsibility for the cause of the shutdown.
“Following a safe landing in Osaka, an appropriate safeguard system on the 787 was activated properly on both engines, triggering the discontinuation of the thrust,” ANA said in a statement. “This system is meant to prevent the aircraft from becoming unstable after landing when thrust is shifted again from reverse to forward. This safeguard system will not be ready for activation unless it detects that the landing gear is on the ground, and an instrument measuring the altitude will not allow maneuver of the thrust reverser during flight.”
Engine manufacturer Rolls-Royce did not immediately respond to a request for information, and Boeing declined to comment.
