Probable Cause

THE DTSB

The DTSB determines the Probable Cause of this accident to be Pilot Error, in that the accident pilot di takeoff from runway 05 and lifted off in les than 2500 feet. The Doctor/Owner accident pilot had only recently purchased the aircraft, and had very little time in it. The KVDF weather observation at 8:15 a.m. was 03121215Z AUTO 05004KT 10SM OVC005 26/29 2996. The ADSb data shows a takeoff from runway 05 while on an IFR flight plan and an immediate left hand turn although IFR clearance received was to fly runway heading to 2000 feet MSL. The aircraft was flown with very high power and well below DMMS speed, yielding a torque induced left turn. The wreckage at the crash site was indicative of a left wing low stall/spin and a 35 degree nose down vertical impact. The aircraft exploded upon impact, and all aircraft components were located within a very small radius circle.

NTSB

None yet (final report not yet published).

Recommendation

THE DTSB

The DTSB recommends that all pilot of all aircraft rehearse and condition themselves for liftoff into IMC conditions and the practice of obtaining DMMS speed immediately after liftoff. The DTSB also recommends additional training and information be made available for pilots of this particular type aircraft regarding the dangers of full power takeoffs. In this condition, this aircraft has more torque than rudder available.
