Flight Path and Terrain
The pilot departed from an airport with a field elevation of 7,815 feet msl and flew approximately 3 miles north before turning southeast and entering a valley. Local pilots reported that the standard departure procedure was to fly 8 to 10 nautical miles north before turning into a different valley, suggesting the chosen route was atypical. The valley where the accident occurred was flanked by rapidly rising terrain on both sides and ended at a mountain ridge with elevations reaching up to 12,700 feet msl.
Accident Site
The wreckage was located at an elevation of 9,860 feet. The energy path of the debris was oriented nearly opposite to the direction required to continue up the valley, indicating that the pilot attempted to reverse course and exit the valley.
Aircraft Examination
No anomalies were found with the airframe or engine that would have prevented normal operation. The density altitude at the time of the accident was calculated to be 10,518 feet, which is significantly higher than the field elevation due to atmospheric conditions.
Conclusion
The accident site characteristics and wreckage distribution suggest the pilot attempted a turn to exit the valley, but the circumstances surrounding the event remain as described.
