Engines Quit On Landing 787
All Nippon Airways, Japanese authorities and Boeing are investigating why both engines on a 787-8 shut down simultaneously during rollout at Osaka Itami Airport last week. The engines quit right after the crew selected thrust reversers on touchdown and the aircraft rolled 8,000 feet before coming to a silent stop, according to samchui.com. The crew worked with technical staff for 40 minutes to restart the engines but couldn’t get them going so the plane was towed to the gate.
A subsequent inspection revealed no faults with the engines but the website says a service bulletin issued by Boeing warned that mishandling the thrust reverse controls can cause the Thrust Control Malfunction Accommodation system, which guards against inadvertent asymmetrical high thrust situations, to activate. The bulletin reportedly says problem can occur if the thrust reversers are deployed too soon after touchdown.
