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 out on a remote, gravel/sand bar, the main landing gear wheels encountered an area of uneven sand and the airplane bounced and pitched into the air. She attempted to correct to no avail. Subsequently, when the airplane touched down from the bounce, the wheels dug into the sand, and the airplane nosed over, resulting in substantial damage to the wing struts. The pilot reported that there were no preaccident mechanical malfunctions or anomalies that would have precluded normal operation.
