The NTSB's narrative final · quoted from the NTSB record
The pilot reported that he was returning from a local area flight and made a normal approach with a 3 point touchdown. After touchdown, the left wing lifted and the airplane veered to the left. He was unable to maintain directional control so he initiated a go-around. The airplane briefly became airborne before the right wing dropped and struck the ground and the airplane came to rest facing towards the east. According to the weather station located on the airport, the wind was reported as calm at the approximate time of the accident. However, during the time period from an hour before the accident to an hour after the accident wind conditions were reported as varying from 254 to 294 degrees with speeds of 7 to 9 knots.
