What happened
During a mid-morning flight, the pilot departed from an airport with the intention of traveling to a destination located 63 miles to the northwest. While the departure airport experienced visual flight rules (VFR) conditions, the weather along the route was characterized by marginal VFR, and no specific weather data was available for the destination airport at the time of departure.
GPS tracking data showed the aircraft initially traveled west along a highway corridor, maintaining an altitude between 900 and 1,200 feet above ground level (agl) while passing through a mountain pass. Approximately 29 minutes into the flight, the aircraft's path turned southwest, moving away from a patch of heavy precipitation and toward an isolated mountain peak that stood roughly 1,000 feet above the surrounding landscape.
During this period, the pilot contacted local air traffic control to report the aircraft's position and to request traffic advisories for the local airspace. Roughly six minutes later, the pilot reported difficulty maintaining VFR and requested an instrument flight rules (IFR) clearance. Simultaneously, GPS records indicated the aircraft had descended to within 50 feet of the mountainous terrain. The final GPS position was logged one minute later at 500 feet agl, about half a mile from the crash site, where the rising terrain intersected the flight path.
Findings
Weather observations from a nearby airport, located 4 miles from the site, noted overcast clouds at 1,500 feet agl and a variable ceiling between 1,200 and 1,800 feet agl, accompanied by drizzle. Radar imagery from the time of the accident confirmed the presence of precipitation at the crash location, suggesting that mountain obscuration likely contributed to the pilot's inability to maintain visual separation from the terrain.
