Ice accumulation blamed for Heathrow Boeing 777 crash landing?

[Grumps]

Following the Boeing 777 accident at Heathrow last week, the American
Federal Aviation Administration (FAA) has just released an
Airworthiness Directive (AD) with the following title:- (Note that the
engines referred to are SPECIFICALLY Rolls-Royce which will be a major
blow for the Derby operation.)

[This AD has been issued] to prevent internal engine damage due to ice
accumulation and shedding, which could cause a shutdown of both
engines, and result in a forced landing of the airplane.
This AD becomes effective February 27, 2008.

Details here:-

Note that at this time the UK AAIB (Air Accidents Investigation
Branch) has not confirmed the finding.

Rolls Royce needs to install carb heat? <G>

Perhaps I am missing something, or am just dense, or both. <g>

Is the implication that a ground ice fog incident, prior to the forced
landing, damaged the engines of the recent 777 Heathrow crash?

If not, what does this report (which seems to only speak about ground ice
fog) have to do with the crash?

Oh, poppycock. The AD addresses a problem that only occurs during ground
operations, and the 777 accident occurred at the end of a long flight at
altitude. An NRPM on this subject had been released in August of last year, five
months before the Heathrow accident. So trying to tie this to the recent
accident is ridiculous.

A most unfortunate time for this AD to come out for Rolls-Royce. Even if
the events are unrelated.

Actually, stuff like this comes out all the time. Minor refinements in
operation because of some difficulty or another encountered. Pretty much
all jet engines are operaed in this fashion and this AD seems to be pretty
much standard stuff. I'd say it's issue at this time is purely
coincidental.

Nope, you are way off base... it was Gremlins that caused the crash.
