Primary finding
Probable cause
The pilot's loss of directional control and subsequent "ground-loop."
Investigator assessment
Analysis narrative
The pilot reported in a telephone interview that he planned to do proficiency landings during the early morning hours. During one of the landings, the wing began to lift and he was not able to regain directional control of the single-engine tail-wheel equipped airplane. The airplane then "ground-looped", and came to rest inverted on the runway. The pilot further reported that there were no mechanical malfunctions or failures with the airplane.
