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.
|
Awesome
You guys are good...:D
|
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.

Here is an update on the BA777 accident: http://www.aaib.dft.gov.uk/latest_ne...in_s1_2008.cfm 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.

The RR Trent engines have literally millions of hours in service worldwide. Time will tell. |
Another reason I'd rather fly with zero-automation - because then, at least, you know exactly what is going to kill you - you don't have to guess!

As you might expect, AA, Boeing and RR have all responded quickly to this reported incident involving an AA B777.
Without going into specific details, because they have been provided in confidence, preliminary indications are that this AA incident - whilst obviously of great concern - is not currently thought to be similar in nature to the recent BA B777 accident involving G-YMMM. Preliminary indications tentatively suggest that the AA aircraft suffered some form of autothrottle malfunction, apparently confined to the left engine, but that both engines always produced their commanded thrust levels. |
Out of the thousands of flights that this aircraft has performed I would think that two related incidents of this nature so close together would be purely coincidental. Of course i fly the thing for a living so I'm leaning towards the positive side. The thing's have never so much as burped on one of our aircraft, and we have Trent powered 777's.

Look for a grounding notice soon, or a revocation of EROPS for RR

Some of BA 777s are GE90-powered.

Not many operators selected PW engines on the B777!

Perhaps. But the 777 launch customer and operator of the largest fleet of 777's in the United States did choose PW. No problems with the PW that I am aware of. That is my only point.
Jsled, Is UAL the only PW 777 operator in the US? Just curious as to why nobody else ordered them with PWs. 73 Longtime PW fan (no pun intended ;)) |

Ok. But the one that crashed was RR, right? Seriously, I am asking?
