Investigator assessment
Analysis narrative
The pilot of the tailwheel equipped airplane reported that, during the landing roll the airplane veered left, he attempted to correct with opposite right rudder. The airplane then ground looped, the right wing struck the surface, and the airplane nosed over coming to rest inverted. The airplane sustained substantial damage to the empennage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
