Primary finding
Probable cause
The pilot's inadequate evaluation of the environmental conditions which resulted in exceeding the climb capability of the aircraft. The inadvertent stall was also a cause. Factors were the downdraft and high density altitude.
Investigator assessment
Analysis narrative
During the takeoff with a computed density altitude of 9,500 feet the pilot reported that at approximately 100 feet agl the airplane would not maintain the proper climb rate and was in a downdraft. During the aborted takeoff the airplane entered an uncontrolled descent when the pilot stalled the airplane. The airplane came to rest in the inverted position off the side of the runway. The airport is located in mountainous terrain and gusty winds prevailed in the area.
