What happened
The aircraft departed from a short, packed snow strip measuring approximately 1,000 feet in length. The airfield was situated at an elevation of 9,500 feet mean sea level. The pilot executed a departure along the downwind leg while climbing over a steep downslope. The flight path required navigating directly down a narrow canyon.
The investigation
Environmental conditions played a critical role in the accident sequence. Lighting was described as flat, providing insufficient contrast to distinguish the snow-covered terrain from the surrounding landscape. This lack of visual reference made it difficult for the pilot to perceive the ground profile accurately during the initial climb phase.
Findings
The airplane struck rising terrain shortly after takeoff. The combination of a steep departure path, high elevation, and poor visual cues contributed to the loss of situational awareness regarding the ground proximity.
