## Analysis

The pilot was landing a tailwheel-equipped airplane on a remote, unimproved airstrip. During the landing roll, the main landing gear struck a concealed tree stump, and the airplane nosed over, sustaining substantial damage to the wings and fuselage. There were no reported preaccident mechanical anomalies with the airplane that would have precluded normal operation.
