Bad Times for the Triple 7 (777)

American investigates as 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.

In an information statement to members, the Allied Pilots Association – which represents American Airlines cockpit crew – says the aircraft experienced a “hang-up” of its left-hand engine.

“The auto-throttles were on and the left engine hung at approach idle as the right engine accelerated normally,” says the association.

“It is believed that the left engine would not respond to throttle inputs for 10-15 seconds before finally responding and accelerating to the commanded thrust.”

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

Maintenance personnel have downloaded the flight-data recorder information and will examine the fuel tanks and engine fuel filters for possible contamination. Tests will also be carried out on the electronic engine control.

Neither the US FAA nor the US National Transportation Safety Board has given any further information on the incident. The pilots’ association has not identified the specific aircraft involved. American Airlines could not immediately be reached to confirm the incident.

Investigators in the UK are still trying to determine the reasons why both Trent 800 engines on a British Airways 777-200ER failed to respond to throttle-increase commands during final approach to London Heathrow on 17 January, resulting in the aircraft crashing short of the runway.'

Well the theory is that there's a problem with a recent software update on the triple seven...

Only too bad this is what happened with the British Airways 777-200..

Pics or it didn't happen.

A link would be nice too.

American Airlines Investigating Similar 777 Incident as BA Flight

Flight International reported today that American Airlines is investigating an incident Thursday in which the engine on one of its Boeing 777-200ERs apparently failed to respond to throttle commands for several seconds during an approach into Los Angeles.
The incident, at this point, sounds somewhat similar to the problem that caused a British Airways 777-200 to land short of the runway at Heathrow recently. Both aircraft were equipped with Rolls-Royce Trent 800 engines.
According to the column,

"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.

In an information statement to members, the Allied Pilots Association – which represents American Airlines cockpit crew – says the aircraft experienced a “hang-up” of its left-hand engine.

What do you guys think? Rolls Royce engines? Or the software update on the triple sevens?

Heard about this about a week ago.

Its funny how people relate this to BA problem. On the report, they found nothing wrong with the engines. They found it more likely with the fuel, that enough wasn't going to the engines or something. On other forums I heard the suggesting a software bug in the 777s, but who knows?. The 777 is still a safe aircraft, as many more operators around the world have not received any problems.

Most definitely software or fuel error.
The 777, as Matt said a very safe plane. Otherwise there'd be more
reported errors.
