BA38s engines "Hesitated"
Dear lomapaseo,
You and a few others think, that I should wait for the AAIB or drop my theory of possible engine ice produced "hesitation"
OK, can you explain, why the FAA issued an AD on the 23. jan. 2008, only six days after BA38s "grass-landing" in order 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"
It was a 10 page AD called 2008-02-05 (or Directorate Identifier 2005-NM-263-AD) effective Feb. 27. 2008.
Valid for: Boeing Model 777-200 and -300 Series Airplanes Equiped With Roll-Royce RB211-TRENT 800 Series Engines.
Read it yourself, the improved procedure, calls for a more strict "engine anti-ice ON GROUND procedure" why this can avoid shut downs when airborne beats me. But it is the only change of procedures, since 17. jan.
2008.
So, at least the FAA thinks that engine ice might be the villain, why have the AAIB not commented on this AD.
