catchup: about the 310 ,as much as I know,it was not a frozen lever.
It was a malfunction of the autothrust coupled with a capt incapacity(heart attack or similar),and probable misreading of the eadi by the f/o,while in low alt turn ,in clouds,just after take-off,with a failed autothrust which increased one engine thrust while decreasing the other one,unfortunately the one inside the turn.
The f/o was an experienced pilot,but new on bus,just came from russian type airplanes.On those planes the artificial horizons works opposite than the western ones (the airplane simbol is turning,while the horizon is fixed).
So ,a chance to increase bank,when you actually try to decrease it.
May them rest in peace.
flash8:i stand corrected.So,it is possible to stuck a lever.I don't know about this case,but i suspect the crash was a CFIT case.
