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, during the landing roll, the airplane veered right. He applied left rudder, and the airplane straightened out, but it then began to veer right again. He stated that he then overcorrected with excessive left rudder control and that the right wingtip impacted the runway. The right-wing trailing edge spar was substantially damaged. The pilot reported that there were no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
