So over 24 hours has passed and you still not answered the question of fwd airspeed.
It is impossible to make the statment that the prop was at 2000 rpm with out knowing the airspeed to make the statement as fact.
Then even if the prop is at that speed its still not an indication of power being produced by the engine. Only the torque of the engine is a reflection of power being produced.
As for flap. Was it set, was it going down, was it being retracted.
The only thing that the initial report has relly given is the gear was down and locked.
The only thing with the ASTB is th hey will find weather true or not a reason/explanation for this accident they will not just say we dont know what happened. Also being the type of aircraft involved one would imagine that all maintenence has been done and as a general rule to a much higher standard than GA lower grade aircraft.
