777 Loses power in LA yesterday.
 
Anyone with details? I hope Boeing gets this thing solved soon.

Can you be more specific...provide a source maybe?

The rampers pulled the ground power before they were supposed to.

Not a big deal if still on the ground. Now airborne, that's a different story.....
BA 777.

From another aviation board:

This is APA Communications Director Gregg Overman with the APA Information
Hotline for Thursday, February 28.


777 SAFETY ALERT: This afternoon American Airlines Flight 229, a Boeing 777
bound from MIA to LAX, had the left engine hang up on approach to LAX at
approximately 2,000 feet. The auto throttles were on and the left engine hung at
approach idle as the right engine accelerated normally. 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. The right engine
performed normally. Maintenance has downloaded the DFDR data and Maintenance
action to be taken (ATBT) will be to sump the fuel tanks, pull the engine fuel
filters and check for contamination, BITE check the EEC and check the MAT for
any existing faults. We will continue to update you as we get more information.

This is definitely cause for concern. I hope its not a problem for the 777.

Ditto.

Here is an update on the BA777 accident:

Sounds like in the BA case, the investigators are looking into evidence of cavitation in the engine fuel gear pumps.

This will be a huge set back if source is not identified soon...

British Airways and American have Rolls-Royce engines on their 777's. No Pratts have lost power that I know of. Could be a Rolls problem.
