The accident occurred on the first test flight following the completion of the amateur-built airplane. The pilot performed high-speed taxi runs followed by a takeoff. The pilot’s flight instructor, who was at the airport watching, observed the airplane southwest of the airport in a spin, from which it recovered. The pilot then flew back to the airport, entered the traffic pattern, and made a radio call that he was going to land. On final approach the airplane appeared to be unstable. The pilot added power and performed a go-around. The airplane came around again for another approach and landing. The airplane appeared to be stable in the traffic pattern until it was on final approach, when it appeared to be unstable as if it were in slow flight. When the airplane was about 200 feet above the ground, the engine noise decreased and the nose immediately dropped along with the right wing. The airplane then impacted terrain short of the approach end of the runway. A postcrash examination of the airplane and engine did not reveal any mechanical failures or malfunctions, nor did the pilot mention any problems with the airplane during his radio calls. The pilot had recently started flying again after not having flown since 1984. He had flown 5 hours with a flight instructor in another make and model of airplane during the 7 months prior to the accident.
Probable Cause: The pilot’s failure to maintain adequate airspeed while on final approach, which resulted in an aerodynamic stall. Contributing to the accident was the pilot's lack of experience in the model of airplane.
