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 the purpose of the flight was to practice landings in the tailwheel-equipped airplane. The pilot said that during the landing roll the airplane veered left. He applied corrective control inputs in an effort to realign the airplane with the runway; however, the airplane continued left and exited the runway surface. During the accident sequence, the airplane’s right wing contacted the ground, which resulted in substantial damage to the outboard section of the lower wing. The pilot reported that he was landing with a left quartering crosswind and that the airplane sustained no mechanical malfunctions or failures that would have precluded normal operation.
