Primary finding
Probable cause
The ingestion of foreign material (snow) in the engine, which resulted in a flameout (loss of engine power). Factors related to the accident were: the adverse weather conditions (snow falling & high density altitude), the lack of snow covers to protect the engine intakes while parked and awaiting for the weather conditions to improve, improper planning/decision by the pilot and the company/operator management, inadequate information in the flight manual, and the lack of suitable terrain for an emergency landing.
