How about digital equipment failure (soft or hard)? No, I'm not
777 qualified.

That seems a possibility although how 2 independent systems (one FADEC
on each engine) would fail like that is seriously puzzling. Did they
possibly have a recent firmware upgrade ? That's given problems in the

Nope.

Yes it has.


Nope.

This PROVES you WRONG !

"We have received a report of two occurrences of engine thrust rollback
(reduction) during takeoff on Boeing Model 777-300ER series airplanes powered
by GE Model GE90-115B engines.

Investigation indicates that these events are the results of a software
algorithm in the FADEC that was introduced in software version A.0.4.5
(GE90-100 Service Bulletin 730021). "
