Double engine failure on ANA 787 raises more concerns over Trent-1000

On January 17th an ANA 787-9 Dreamliner powered by Rolls Royce Trent-1000 engines was coming into land at Osaka-Itami as flight NH985.

On touchdown, as the pilots went to switch the engines to reverse thrust, they quickly realised both engines had stopped working and had to let the aircraft run out the length of the runway until it stopped.

It’s the first known failure of both engines on a modern jet liner where they have failed simultaneously, a situation considered almost impossible.

Investigators from all applicable authorities and Rolls Royce have opened urgent investigations.

The initial cause is suspected to be faulty software. Boeing apparently, recently updated Thrust Management Activation Control instructions designed to stop thrust building too quickly and shutting engines off.
