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 he departed from a remote private air strip and proceeded along a geological drainage ravine for 3 miles, then turned up a side canyon into rising terrain. As the airplane approached a saddle in the terrain the pilot spotted 2 black bears. The pilot entered a descent and executed a right turn to orbit the bears. After a 360-degree turn he realized that the airplane had descended too low and was approaching rising terrain. The airplane's slow airspeed and angle of bank did not allow for recovery and the airplane subsequently collided with the terrain and nosed over. The wings and fuselage were substantially damaged. The pilot reported no preimpact mechanical malfunctions or failures of the airplane that would have precluded normal operation.
