Analysis

The pilot of the tailwheel equipped airplane reported that shortly after touchdown, during the landing roll, the airplane veered left, exited the runway, and ground looped. Subsequently, the right wing impacted the ground and sustained substantial damage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
