Probable cause

Failure of the pilot to maintain adequate airspeed resulting in an inadvertent stall while on final approach. Factors were the high density altitude and the pilot's poor approach planning.

Analysis

The airplane departed controlled flight and hit the ground in a nose down attitude while on final approach for a short field landing. The pilot was attempting to land in a small field about 120 yards wide. The airplane was observed about 20 feet above ground level entering a left turn on short final approach to the field. The airplane's speed was described as slow. The airplane's nose was observed to pitch down rapidly. Another pilot indicated he saw the airplane stall. The accident site elevation was about 5,600 above sea level, and the outside air temperature was estimated as 85 deg f.
