I got this from a friend and thought you would like it.

Subject: Gastwick B-777 Info
I recently received this from a Retied DL Colleague. I do not know the
identity of the author. I have done some small bit of editing for my non
pilot friends.

Heard from a friend regarding the U.K. 777 crash. As I recall this aircraft
had Trent engines built by Rolls Royce.
******************************
*********************************
This is part of a message forwarded to me:
Had the pleasure of chatting with a member of the NTSB board last night at
dinner. Here is what he shared. Aircraft was at 600 ft agl (Above Ground
Level ) when the right engine (RPM) started to roll back to slightly above
flight
idle.
The First Officer was flying and auto throttles were engaged. The auto
throttles moved the throttles up to catch the deceleration in airspeed. The
right engine did not respond to the movement of the auto throttles. The
First Officer disengaged the auto throttles and manually moved both
throttles to max power as the Captain joined him and they both applied
emergency power. Within 8 seconds of the right engine rolling back to just
above flight idle the left engine did the exact same thing. The engines
never changed RPM from that point till ground contact. The F/O continued
flying and kept nibbling on the stick shaker to clear a hill just prior to
the impact point. Apparently the crew is being hailed as heroes for their
performance.
The two areas under investigation are fuel that was uplifted in China. Ice
in the fuel is a consideration and they are running chemical test at this
time. The other area is engine software. So far they can confirm that
everything from the throttles to the ECC's worked as it should. Its the info
from the ECC's to the fuel controller that is in question. This aircraft
had just had a software update 2 days earlier

Folks,
Anybody interested can download the progressive reports from the UK
at
http://www.aaib.dft.gov.uk/latest_news/accident_to_boeing_777_236__g_ymmm__at_heathrow_airport_on_17_january_2008___initial_report_update.cfm
As a matter of interest, the air masses over Russia/CIS/Eastern
Europe were particularly cold that morning, aircraft were having to
come as low as FL250, and maintain higher than LRC Mach No. to
maintain fuel temps. warmer then -37C.
Cheers,
Bill Hamilton
