Faulty Engines Blamed For Heathrow Crash
http://www.theksbwchannel.com/news/15088682/detail.html
LONDON -- The engines on a British Airways plane that crash-landed at London's Heathrow Airport failed to respond for a demand to increase thrust about two miles before it reached the runway, a preliminary accident report said Friday.

Using flight recorder information, investigators will focus on what might have caused the engine problem on British Airways Flight 038 from Beijing to London, according to the report from Britain's Air Accidents Investigation Branch.

The British Airways Boeing 777 made a crunching touchdown short of the runway on Thursday, ripping off the plane's landing gear and severely damaging the two engines and wings. Nineteen injuries were reported among the 152 people aboard.

The reason I bring up this airplane accident is first the pilot and copilot were fantastic

and because many rumours are mulling around the air industry about how in the world two engines just shut down two miles before the runway

the news articles are not telling the whole story here
and its very unusual for both engines to go out

they are saying a bird strike or fuel shortage
but many pilots out there are wondering what the heck turned off two engines
Amazing story and suspicious one at that

3. The engines need two things
Air and Fuel and I think the last thing was lacking as the wings that hold the fuel were damaged and no fire resulted from the landing.

6. How does a 777 run out of fuel without anyone noticing?
It'd be pretty easy to prove this if it were true, because you'd have a 777 with empty fuel tanks.

9. Even though the wings were damaged there was no fire
Check here for out of fuel incidents and you will se that these do happen.

12. There was plenty of fuel on the plane at the end
Edited on Fri Jan-25-08 06:15 AM by muriel_volestrangler
but the pumping of it is being examined. A recent article (rather than the week-old one in the OP):

When the automatic throttle demanded more power, the engines initially responded. Then first the right engine, followed eight seconds later by the left, powered down - to a level below the thrust needed.
...
The plane had not run out of fuel, and there is no mention of birds being sucked into the engines, or violent blasts of wind throwing it off course.

In fact, both engines were turning as the plane hit the ground.
...
It is this collection of computers, tanks, pumps, sensors and their backups, which the investigators are examining closely.

They're also looking at low temperatures causing fuel waxing.

4. It was the mechanisms to move the plane, not the engines. We're waiting. nt

7. The first thing Mr. Tesha said when he heard the news story was "Firmware bug".
The first thing Mr. Tesha said when he heard the news story
(about how both engines lost power simultaneously) was
"Firmware bug". That is, a bug in the onboard computer
program(s) that control the engines.

And I think there'as still a pretty good chance that he
nailed it.

8. I find bugs for a living.
And I wouldn't be at all surprised if that were the case. Mechanical failure in two engines at once seems implausible.

Funny story - remember when one of the Mars rover's software crashed? My employer at the time, a maker of set-top boxes, had been trying for months to get WindRiver, who make the OS that runs both the Mars rovers and my old company's products, to fix that stupid fucking bug.

11. IMO, they need to look for a ground hacker 2 miles back. n/t

14. Please be more specific. For example, do you think these engines communicate using Wi-Fi? (NT)

10. What do you suspect?
Sabotage?

13. I wondered about fuel shortage at first but
one of the BBC articles said fuel was leaking after the crash landing. It's very odd that a bird would hit one engine and knock out all of them.

15. It seems to me that an overall fuel shortage could be ruled-in or ruled-out quite quickly.
Edited on Fri Jan-25-08 06:57 AM by Tesha
Now fuel management problems, *THAT* might take a bit longer.

(Crude example: the death of John Denver where he crashed
when he drained *ONE* of his fuel tanks dry while the
other tank still had plenty of fuel in it.)
