According to the pilot, he elected to land at the accident airport since there were thunderstorms between him and the destination airport. He landed the airplane without incident and was taxiing to the tiedown area when the wind increased. The wind lifted the tail of the airplane, it nosed over, and came to rest inverted, resulting in substantial damage to the wings and empennage. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation. The weather reported at an airport located six miles to the east of the accident location included thunderstorm activity and winds from 240 degrees at 14 knots, gusts 19 knots, and the peak wind was recorded at 52 knots.
