2 people were known to be on board, 1 fatalities were recorded, 1 survivors were identified or estimated. This corresponds to an estimated fatality rate of 50.0%.

The listed crash cause is technical failure. The CFR Part 135 cargo flight departed at night on an IFR flight with a load of mining equipment. Route of flight was over remote/mountainous terrain. About 2 hours after takeoff, while cruising at 12,000' feet msl, the right engine and propeller began to overspeed. The captain feathered the #2 engine and declared an emergency. He began to divert to an alternate destination, about 120 miles away in an area of lower terrain, but the aircraft would not maintain altitude (single engine service ceiling, as loaded, was about 8,700 feet). The captain increased power to the left engine, but it began to produce banging and coughing noises. The captain elected to perform an emergency landing at a nearby, remote, military airfield (A/F). The A/F was located in mountainous terrain and had a one-way, daylight only approach. The captain lowered the gear and flaps, and began a visual approach while attempting to keep the runway end identifier lights (REIL) in view. The aircraft encountered severe turbulence, and the captain applied full throttle to the left engine in an attempt to climb. The REIL disappeared from view, and the aircraft collided with snow covered terrain about 2 miles west of the A/F. Ground personnel at the A/F reported high winds and blowing snow with limited visibility. Postcrash exam of the right engine revealed a loss of the propeller control system hydraulic oil. Flight at 12,000 feet was conducted without crew oxygen. The crew had exceeded their maximum allowable duty day without adequate crew rest.

Aircraft reference details include registration N702SC, MSN 126, year of manufacture 1963.

Geospatial coordinates for this crash are approximately 61.0960°, -155.5746°.
