The airplane touched down on the runway and was on landing roll out. The pilot stated a gust of wind from the right rear lifted the tail of the airplane up and the airplane veered to the left.

In addition, the airport manager stated there were no wind gusts present at the time of the accident. A witness stated that the airplane was about 6 to 7 feet off the runway. The wings were rocking from right to left, and the crosswind was pushing the airplane across the runway to the left. The accident pilot stated that when the airplane started veering to the left he applied right rudder and left aileron, which had no effect. The airplane went off the left side of the runway into the grass and nosed over inverted. The airplane sustained structural damage to the airframe and the pilot reported no preexisting mechanical problems with the airframe, flight controls, engine assembly or accessories.
