What happened
A pilot and passenger departed from a remote airstrip on a commuter flight under marginal VFR conditions. While crossing low hills at approximately 1,000 feet AGL, the pilot encountered turbulence and perceived a possible loss of engine power. Although the engine did not exhibit rough running, the aircraft continued a descent until it struck a snow-covered hill located roughly 15 miles west of the destination airport.
The passenger noted that downward visibility was limited for much of the flight. Immediately preceding the impact, the passenger reported experiencing white-out conditions where no terrain could be seen. The accident resulted in damage to the aircraft's wings, fuselage, and landing gear. Both the pilot and the passenger were rescued approximately four hours after the impact.
At the destination airport, weather observations indicated an overcast ceiling of 1,300 feet and visibility of 10 miles in light snow.
