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 said that he was practicing his takeoffs and landings on runway 22L and the wind was from 160 at 10 knots. The airplane touched down and bounced, and then the pilot transitioned the airplane to a three-point landing. The pilot reported that the wind lifted up the left wing. He attempted to correct; however, the tailwheel was not yet on the ground. The airplane veered to the left and the right main landing gear collapsed. A witness reported the airplane bounced when it landed, and then it ground-looped, collapsing the right main landing gear.
