Analysis

The pilot took off from an airport and reportedly turned downwind at about 400 feet AGL. Witnesses reported that the aircraft appeared to be in a 'steep' bank. They said that the aircraft 'appeared to fall off on the left wing and spin into the ground.' An FAA airworthiness inspector examined the aircraft on scene and reported that no discrepancies could be found that would have hampered the aircraft's ability to fly and maintain altitude. The pilot's recent aeronautical experience could not be determined. His medical certificate was expired.
