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 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.

Factual narrative

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. In the recommendation section of the NTSB Accident/Incident Reporting Form 6120.1, the pilot stated that the accident may have been prevented if he would have selected a more suitable off-airport site.
