American Airlines 777 engine fails to respond to throttle

American Airlines is investigating an incident yesterday during which the engine on one of its Boeing 777-200ERs apparently failed to respond to throttle commands for several seconds during approach to Los Angeles.

The incident involved American’s flight AA299 from Miami and occurred at a height of around 2,000ft as the aircraft was descending to Los Angeles

luckily it was 1 engine not both BUT heres the telling info:

All of American’s 777-200ERs are fitted with Rolls-Royce Trent 800 powerplants

BA uses Trents as well

Very troublesome. Boeing better get a handle on this fast.

I agree DBS. The 777 has an excellent safety record as of now. No need to ruin that with a bad reputation. I bet Boeing engineers are sweating bullets.

Just to point out it was a 777 that crashed at Heathrow when the engines failed to respond and give more power.

I'm sure you all knew that though

just read something on pprune which has got me thinking;

Loss of engine thrust control is nothing new indeed looking back through my manuals there was a bulletin about 'loss of engine thrust control' issued by Boeing in my company FOM in January 2001. I guess the surprise was that it could happen in two engines at the same time. Clearly occurrences had occurred prior to the bulletin written 7 years ago.

a big `what if` boeing knew about this allready but it hasn`t been corrected?
