## Analysis

The pilot of the tailwheel equipped airplane reported that, after executing a normal three-point landing and during the landing roll, the airplane swerved to the left. He attempted corrective action, however the airplane then swerved to the right. The pilot applied brakes, and the airplane ground looped, substantially damaging the right wing. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
