Probable cause
The pilot's failure to maintain directional control during the landing roll.
NTSB analysis
The pilot stated that the airplane touched down uneventfully. During the landing roll a gust of wind picked up the right wing, the pilot applied right aileron and right rudder correction to regain control, but was unable to do so. The pilot lost directional control and advanced the throttle to the full position in an attempt to execute a go-around, subsequently the left wing came in contact with the ground and ground looped, which resulted in substantial damage to both of the left wings and left lift struts.
The pilot reported no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
