What happened
The accident occurred during a night cross-country flight following an extended 16-hour duty day. The pilot, who served as an airline captain, was operating his own aircraft on a personal trip home. At the time of the incident, the weather conditions were visual meteorological conditions (VMC). The aircraft was flying at an altitude of 10,000 feet when it collided with a mountain. This event took place approximately 17 miles from the intended destination. The aircraft was in a stable, shallow descent phase when the collision occurred.
The investigation
Investigators examined the flight conditions and meteorological data relevant to the accident site. The analysis focused on the wind patterns aloft during the flight. It was determined that winds were strong at the altitude of the aircraft. These winds would have drifted the aircraft toward the mountain terrain if no wind correction angle had been applied by the pilot.
Findings
The primary factors contributing to this accident included the pilot's decision-making after a long duty day and the failure to account for significant wind drift. The strong winds aloft created a hazard that required active compensation, which was not utilized. The proximity to the destination (17 miles) suggests the pilot may have been focused on arrival rather than maintaining precise track relative to terrain.
Safety message
Pilots operating after extended duty periods must remain vigilant regarding navigation and wind correction. Strong winds aloft can rapidly displace an aircraft from its intended track, particularly during night VMC conditions where visual references may be limited.
