Probable cause

The pilot's failure to maintain sufficient terrain clearance altitude during a low altitude turn. Contributing to the accident was the pilot's poor judgement in conducting touch-and-go landings with a 700-foot ceiling.

Analysis

Pilot only remembers doing touch-and-go landings with a 700 ft ceiling. Witnesses observed the airplane buzz a hangar twice, then do a touch-and-go. At the end of the runway the aircraft did a hard left turn. The wingtip dug into the ground and the airplane cartwheeled.
