Accident Overview
A witness reported observing the airplane approach the runway threshold at a high rate of speed and altitude, descending at approximately a 45-degree angle. According to the witness, the airplane then pitched up steeply and eventually leveled off, appearing to fly at a safe speed. Other witnesses saw the airplane strike trees as it passed near their home.
Pilot Account
The pilot stated that the airplane was in ground effect and nearing trees at the departure end of the runway. He reported adding full power and retracting his flaps until he finished a 5-count. He said that the airplane's tires collided with the trees, and shortly thereafter the airplane stalled and rolled left, descending vertically into the roof of a shed.
Pilot's Approach Technique
The pilot explained that he uses the airspeed indicator and altimeter to help judge the glide path to landing. He said he aims the airplane's nose at the runway aiming point and flares when the approach is stabilized.
Instructor Interviews
Interviews with two of the pilot's flight instructors revealed that they were unable to explain how to fly a final approach and then land the airplane on the first quarter of the runway.
Conclusion
The accident sequence involved the airplane striking trees, stalling, and rolling left into a shed roof after the pilot applied full power and retracted flaps in an attempt to clear obstacles.
