Investigator assessment
Analysis narrative
The pilot reported that during the crosswind landing, the tailwheel equipped airplane touched down about 10 knots too fast, and the tailwheel started to shimmy. The flight instructor assisted the pilot with the controls as the airplane exited the runway into the adjacent grass area. However, the pilot was unable to regain control and the airplane ground looped. According to the flight instructor, the pilot had previously demonstrated proficiency in the airplane. The flight instructor reported that he did not intervene in a timely manner. The airplane sustained substantial damage to the left wing and fuselage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
