Aircraft involved

Probable cause & findings

The pilot's failure to maintain directional control during landing.

Factual narrative

The pilot reported that following an uneventful landing in a tailwheel equipped airplane, the airplane bounced and settled back onto the runway in a two-point landing configuration. Subsequently, the airplane suddenly veered to the right. Despite the pilot's control inputs, the airplane ground looped and exited the right side of the runway. Examination of the airplane by the pilot revealed that the left wing sustained structural damage. The pilot reported no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
