Primary finding
Probable cause
The pilot's selection of an unsuitable, off-airport site, which resulted in a nose over.
Investigator assessment
Analysis narrative
The pilot reported that while departing in a tailwheel-equipped airplane, from a rough and uneven tundra-covered off-airport site, it failed to gain sufficient airspeed, and he aborted the takeoff. The airplane's main wheels sunk into the soft tundra-covered terrain, and the airplane subsequently nosed over, sustaining substantial damage to the wings. The pilot stated that there were no preaccident mechanical anomalies with the airplane that would have precluded normal operation.
