Investigator assessment
Analysis 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.
