767 Double Engine Failure.
 

Earlier this year a Boeing 767 suffered a double engine failure in the Pacific area.
Does anyone have any details on this incident? It all seems to have gone very quite.

I bet it did!

I hope it wasn't at night time, coz it's a real bugger in the sim when it happens. You can't see a bloody thing in the F/O's seat. Bit of a fumble in the dark to try and find the engine start switches and the APU starter.

But then again, that might just be the sim. Hope to god I never have to do it for real...

LMAO BusyB :) :) :)

(-23) ON MARCH 4, 2001 AT 1530 LOCAL TIME, UNITED AIRLINES (UALA)
BOEING 767-322, N666UA, FLIGHT 42, (OGG-LAX), EXPERIENCED A POWER LOSS
IN BOTH ENGINES WHILE CLIMBING THROUGH 24,000 FT. THE FLIGHT CREW WAS
ABLE TO RESTART BOTH ENGINES AND THE AIRCRAFT WAS DIVERTED TO KONA
INT'L AIRPORT, KEAHOLE, HAWAII. THE AIRCRAFT LANDED IN AN OVERWEIGHT
CONDITION AND ENCOUNTERED A BRAKE FIRE ON ROLLOUT. THERE WERE TWO
FLIGHT CREW MEMBERS, TEN FLIGHT ATTENDANTS, AND 238 PASSENGERS ON
BOARD. NO INJURIES REPORTED. INVESTIGATION REVEALED THAT THE CREW DID A
PRECAUTIONARY SHUT DOWN OF ONE ENGINE, AND DUE TO FUEL MIS-MANAGEMENT,
THE SECOND ENGINE SHUT DOWN DUE TO FUEL STARVATION.

Before anyone gets too excited about this incident, it should be noted that further investigation suggests that this was a fuel management problem which resulted in both engines rolling back. It does NOT appear that this was a wildly improbable event of both engines failing at the same time.

The NTSB released the following report on 14 March: http://www.ntsb.gov/Pressrel/2001/010314.htm

This is more than a little worrying as I thought that even with fuel mismanagement (this early in flight could not have been empty tank could it?) then the engines would still be gravity fed from wing tanks aided by engine driven low pressure pumps even with tank booster pumps off or failed. I know there is a note in QRH saying that degraded performance at high altitude is possible with both pumps in one tank failed (OFF) but it is not required to open crossfeed until such degradation occurs. Somehow I have never thought of FL240 as high altitude. I know its not low but not that high either. Obviously rethink required.

That PROFESSIONAL of yesteryear, the FLIGHT ENGINEER, is certainly missed. How many times can the older guys remember WHEN the F/E mis-managed the fuel?

Ah but I seem to recall a Flight Engineer who managed his fuel imbalance by feeding all four engines off one tank. All four stopped when he forgot to monitor the situation and ran the tank empty. Even Flighty's can screw up you know...

Well, only one time.......

Also remember the F/E feeding the fire on Whisky Echo.(1968, EGLL, 707, for us oldies)

I'm suprised the press didn't pick up on the aircraft registration!

If I remember correctcly It was not a Flight Enginner who switched all the engines to one tank and probably fell asleep. It was a second officer (A retired captain who was operating FE panel.)

I am not making judgements, just making a point.

Well think about it Tunturi - If they shut the firewall valve to the wrong engine, all the considerations you mention are irrelevant!

Fuel mismanagement indeed!

I have no direct knowledge of this incident, the above is just a suggestion.

More NTSB "newspeak".

What do they require, abrupt stoppage to call it an engine failure? Both engines below generator cut-in speed for 30 seconds?

Any mention of RAT deployment???

If fuel mis-management was responsible that early in the flight, something is terribly wrong - and it was. Both engines couldn't have failed that close together due to mechanical failure.

Try water in the fuel tanks. But then, there is a cockpit accounting problem that needs addressing.

This whole thing reeks of more FAA & NTSB cover-up. Nothing new in that department.

Sounds like damned good airmanship in the recovery, however.

Mileshigh "Well think about it Tunturi - If they shut the firewall valve to the wrong engine, all the considerations you mention are irrelevant!"

Yes you are absolutely right BUT that is not FUEL mismanagement. Incidentally, anyone remember an Eastern B757 crew who shut down BOTH engines simultaneously using Fuel Control Switches instead of switching of the EEC switches as per the QRH drill that was in hand? Restarted ok and as a result EEC switches moved from behind fuel control switches to overhead panel. The switch designs are not even remotely similar.

Haulin' Trash - But I seem to recall in the Whisky Echo incident that that they simply never got far enough down the check list to cut the fuel? Saw it happen from West Drayton, and taxied past the carcass that same evening ... Sobering experience.

Tunturi:

I belive the incident you are refering to was actually a Delta B-767, the shut down both engines (Accidently) by moving the fuel control levers to "Cut-Off".

The joke at the time was something about Delta's highly efficient Noise Abatment Procedure.

If Eastern had a similar one, I don't remember it.

(Yes EAL had one incident where they shut down one engine on a L-1011 due to loss of oil pressure/quantity, then the same happened to the remaining 2 engines. They re-started the first one and limped back to MIA.
The reason was a wrong oil seal, or the seal installed the wrong way...)

UA had a 747 incident years ago: They lost 3 of the 4 mills and glided into Japan or somewhere. Forgot the exact reason, but fuel managment was probably a player.
(The captain was not in the cockpit at the time.)



------------------
Men, this is no drill...

All interested parties;

The dual engine failure referred to was the result of a botched crossfeed operation that left all pumps off and both crossfeeds closed. Both engines rolled back to a sub idle condition before suction feed commenced. The RAT deployed as advertised and the plane diverted.

The plane in question was extensively test flown and performed as predicted. When the manual says suction feed isn't guaranteed at high altitudes or high fuel flows, you had best believe it!

Contributing to the problem was something called "fuel weathering". Apparently "new" fuel contains a good deal of entrained air that makes suction feed less reliable.

A good refresher for all of us. Suction feed isn't a right, it's a privilege ;-)
