Analysis

The pilot of the tailwheel equipped airplane reported that during the landing roll the airplane started to veer to the right, he attempted to correct with left rudder, which resulted in a ground loop to the left. The airplane sustained substantial damage to the right wing, right horizontal stabilizer, and right elevator. The pilot reported that there were no pre impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
