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 was landing at a 900-foot-long, remote off-airport site in a tailwheel-equipped airplane. He said that during the landing roll, the airplane veered slightly to the right, and then it went down a small embankment. The pilot said he inadvertently applied heavy braking, both wheels "locked," and the airplane subsequently nosed over, sustaining substantial damage to the wings and wing lift struts. The pilot noted that there were no preaccident mechanical anomalies with the airplane that would have precluded normal operation.
