Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that after landing the tailwheel equipped airplane, he applied brake during the landing roll and the airplane started to turn. He applied rudder to correct but overcorrected and the airplane oscillated and then went off the left side of the runway. The airplane subsequently struck a ditch next to the runway. The airplane sustained substantial damage to the right lower wing and the right horizontal tail and elevator. The pilot reported that there were no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
