During the airplane’s initial takeoff climb, two ground witnesses observed the left “gull-wing” entrance door to be open. They reported that when the airplane was about 50 feet above the ground, it entered a series of approximately four pitch oscillations. During the last pitch-down oscillation, the airplane impacted the runway at a steep descent angle and then skidded forward about 500 feet, coming to a stop near the right side of the runway. A postimpact fire ensued. Examination of the airframe, engine, propeller and the door did not reveal any anomalies associated with a preimpact failure or malfunction.
Probable Cause: The airplane's entry into a pilot-induced oscillation and the pilot’s loss of airplane control during the takeoff initial climb. Contributing to the accident was the left entrance door opening in flight for undetermined reasons.
