Circumstances:
The airplane departed Nome on a VFR flight to Shishmaref, about 122 miles to the north. Few minutes after takeoff, the crew encountered poor weather conditions with snow falls, limited visibility (night) and icing conditions. The airplane struck the slope of a mountain located to the north of Nome. As the airplane failed to arrive at destination, SAR operations were initiated but eventually suspended few days later as no trace of the aircraft nor the four occupants was found. The wreckage was localized on February 10, 1980. The aircraft was destroyed upon impact and all four occupants have been found dead.
Probable cause:
Controlled flight into terrain during normal cruise after the crew continued VFR flight into adverse weather conditions. The following contributing factors were reported:
- Snow covered terrain,
- High obstructions,
- Low ceiling,
- Snow,
- Visibility half a mile or less,
- Fog,
- Special VFR flight.

Circumstances:
En route from Anchorage to Galena, the pilot encountered poor weather conditions with low ceiling. Lost and disoriented, he flew into a blind canyon when he saw high obstructions. While initiating an evasive maneuver to avoid collision, he made a steep turn to the left when the aircraft struck the ground and crashed in flames in a mountainous terrain located about 125 miles northwest from the city of Anchorage. As the airplane failed to arrive at destination, SAR operations were initiated but eventually abandoned few days later as no trace of the aircraft nor the pilot was found. On September 2, 1980, the burnt wreckage was found near Rainy Pass.
Probable cause:
Controlled flight into terrain after the pilot became lost and disoriented. The following contributing factors were reported:
- The pilot continued VFR flight into adverse weather conditions,
- The pilot misjudged distance, speed, altitude or clearance,
- Low ceiling,
- High obstructions,
- The pilot flew into blind canyon,
- Evasive maneuver to avoid collision,
