The NTSB's narrative final · quoted from the NTSB record

According to the pilot, during the landing, a gust of wind pushed the airplane to the right of runway centerline. The pilot applied rudder and aileron inputs to counter the unexpected wind. Subsequently, the airplane ground looped and came to rest upright on the runway. A postaccident examination of the airplane revealed the right wing spar was bent. No airframe or engine anomalies were reported by the pilot. The wind conditions at the airport were light and variable at the time of the accident.
