The NTSB's narrative final · quoted from the NTSB record

According to the pilot of the tailwheel-equipped airplane, his intent was to perform a wheel landing, but during touchdown, the airplane bounced and a gust of wind lifted the left wing. The pilot applied left stick and right rudder to maintain directional control. The left wing settled, the nose of the airplane yawed to the right, and the tailwheel settled to the runway. The pilot applied aft stick and left rudder, but the left wing lifted again, and the nose yawed to the left. The right wing struck the ground and the airplane exited the runway to the left, where the right main landing gear collapsed. The airplane came to rest on the right wingtip and began leaking fuel. The airplane sustained substantial damage to the right-wing. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
