Factual narrative
The pilot reported that, during taxi southbound for takeoff he noticed the windsock in a north-northwest wind direction. He had the flight controls in a neutral position and the engine speed was 800 rpm when he encountered a strong gust of wind from behind. The tail of the airplane lifted, and the airplane nosed over coming to rest inverted. The right-wing lift strut and vertical stabilizer were substantially damaged. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
Probable cause
The pilot's failure to maintain airplane control while taxing in gusty wind conditions. The National Transportation Safety Board determined the probable cause of this accident.
