Investigator assessment
Analysis narrative
The pilot of a tailwheel equipped airplane reported that, during the landing roll, while adjusting the flap handle, he briefly stepped on the right rudder and the airplane veered to the right. While attempting to correct with left rudder input, the airplane continued to veer to the right, exited the runway, ground looped to the right and collapsed the left main landing gear. The airplane sustained substantial damage to the left wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
