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 flight instructor reported that, during the last landing of the day, which he performed in crosswind conditions, the tailwheel-equipped airplane bounced. He added that during the bounce, the airplane rolled right, and the right main landing gear touched down. Subsequently, once both main landing gear were on the runway the airplane veered sharply to the right and he lost directional control. The airplane exited the right side of the runway, the right main landing gear spindle and tire separated from the airplane, and the airplane came to rest. The airplane sustained substantial damage to the front spar. The flight instructor reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The automated weather observation system located at the accident airport reported, about the time of the accident, the wind was from 210° at 8 knots. The flight instructor landed on runway 33.
