NTSB Factual Report

The pilot reported that during an instructional flight in the tailwheel equipped airplane, upon touchdown, his application of right rudder control was too aggressive and the airplane subsequently ground looped. The airplane sustained substantial damage to the left wing, aileron, and elevator. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.

NTSB Probable Cause

The pilot's failure to maintain directional control during the landing roll, which resulted in a ground loop.
