Spotted this at www.telegraph.co.uk this lunchtime.

'A report by the Air Accidents Investigation Branch (AAIB) has disclosed that Boeing 777s were involved in at least 12 incidents where electrical systems have overheated during or before flights. Four of those resulted in overheating which caused 'major damage' to power panels involved in controlling the plane.'



I am trying not to think about this as I sit in DXB after taking one 777-200 from BLR and about to board another for LHR!


Best not to watch Air Crash Investigation tomorrow night then [:I]

Well here is a turn up for the book...

The FO was working a flight from Kolkata to Heathrow on the 6th when the left hand engine stoped responding to throttle commands !

And the a/c is still sitting at the end of the runway when I flew yesterday. I know that it is now owned by the insurance company but you would have thought that BA would be pushing very hard to have it moved.

Not the greatest of adverts for them.

Not the greatest of adverts for Boeing as well. I thought it had been moved the a maintenance area?

Yes and it serves as a reminder - I have a number of friends who are now weary of the 777, principally because the cause hasn't been confirmed and no recommendations or remedial actions have taken place to negate future occurences.

What would you suggest the recommendations or remedial actions are?

Until the cause is found, and the AAIB aren't exactly sitting on their hands, you cannot make any recommendations. At the moment the only option based on the investigations made public is to ground the entire 777 fleet worldwide.

I would guess that a distinct lack of 777's falling out of the sky points to a one-off problem rather than something much more widespread.

Darren, I never said that recommendations or remedial actions should be made. I totally agree with all that you say. I do choose VS over BA on the PVG route in part over the equipment, mainly due to seating configuration and noise, this incident doesn't affect my personal trust of the 777 and its safety.
All I was saying is how my friends feel - I'm sure they aren't alone. Once the cause is found and remedial action is taken they will I'm sure be more reassured. Let's face it, no matter how many statistics you throw, some people will always feel unsafe in a plane.

Sorry, I should have been much more general. [:)]

As you say there will always be those who feel unsafe in a plane of any type. Some of them are like that because they don't really understand how they fly, Bernoulli effect, thrust over drag etc. etc.

The same FO was involved???

I find it bizarre that it is aimed only at Rolls Royce engines. Surely the fuel flow was restricted before it got near the engine? Weird

Interim report from AAIB indicated ice in fuel systems as the cause

Interim Report


Wouldn't that point more at the fuel in question rather than RR engines ?

If I'm reading it correctly, the fuel quality easily beat all standards so no problems there. It seems the water (of which some is allowed) in the fuel rather than the fuel itself iced up. The question is how, since the B777 is supposed to filter water out during flight and all system were functioning correctly.

Reading between the lines they still do not have a clue[:)]

Ice, water bollox. Only maybes this maybe that.

Just seen a flash about News at Ten and it's got a lead story about the incident.

Call me old fashioned but I always like looking out the window and seeing two engines on the wing. I know that is fairly illogical but......

While I fully agree you with there about the four engines & admit to preferring having the four engines myself.

Thing is though, that if there was a fuel issue that was common to the feed of both engines on the T7, then its fair to think that a similar issue would affect all four engines on a quad.

Resulting in the same situation.

A 100% loss of power is no different on a quad than a twin unfortunately.

The second interim report has now been released. Here

Still saying it was ice.
