Witness Observation
A witness observed the airplane depart to the south and climb vertically at an approximate 85-degree angle, with the rudder deflected to the right. When it reached the apex of the climb, approximately 200-250 feet above ground level, it began to "fly backwards like a kite," and the engine was "throttled back." The airplane then made a descending left-hand turn in an approximate 45-50 degree nose-down attitude. While in the descent, the elevator was deflected to the full up position. The witness then observed the left wing "drop" and the upward deflection on the elevator decreased. At this point, and while still in the descent, the right aileron was deflected to the full up position, and the airplane's wings leveled out, while the engine "throttled back up to full power." The right aileron stayed deflected, and the airplane turned to the right and contacted the ground with the right wing tip first followed by the engine.
Pilot Experience
Another witness reported that the 410-hour pilot "almost always" performed this type of take-off, and they had observed the pilot perform this maneuver "recently and frequently."
Post-Accident Examination
Flight control continuity was established throughout the airplane at the accident site. No mechanical anomalies were noted with the engine or airframe. The airplane was found to be within weight and balance limits.
