Where does it leave us then?
I think it leaves us with this, from page 77:
throughout the flight, the movements of the elevators and the THS were consistent with the pilot’s inputs,
up to the exit from the flight envelope, the airplane’s longitudinal movements were consistent with the position of the flight control surfaces,
(my bold above)
So that although the movements of the control surfaces were consistent with pilot inputs throughout the entire event, there is no direct statement of finding to the effect that after the aircraft exited the flight envelope the aircraft longitudinal movements were still consistent with these pilot inputs even though control surface positions were. Nor does this appear to imply anything further.
I would imagine this is still being investigated.
