Primary finding
Probable cause
The pilot's failure to maintain directional control during the landing roll, which resulted in a ground loop.
Investigator assessment
Analysis narrative
The pilot of the tailwheel equipped airplane reported that he landed behind another airplane. During the landing roll, the airplane encountered “wake turbulence” and veered to the right. He applied power in an attempt to regain rudder authority and execute a go-around; however, the airplane exited the right side of the runway, ground looped, and the right wing struck the ground. The airplane sustained substantial damage to the right aileron. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
