Probable cause

The NTSB’s determination of the probable cause, and any contributing factors.

Continued VFR flight by the pilot into instrument meteorological conditions (IMC), and his failure to maintain adequate altitude (or clearance) from mountainous terrain. The adverse weather and terrain conditions were related factors.

Analysis

The scheduled flight's departure from king cove was delayed due to a passing snow squall. A witness at the airport stated that the weather at the airport was good when the flight departed; however, he noted dark clouds in the direction of Cold Bay, the intended destination of the flight. The airplane did not reach its destination. It was found, where it had impacted terrain near the top of a ridgeline at the 1250 foot level, between king cove & Cold Bay. About 8 miles west-northwest at Cold Bay, weather reports indicated there were snow showers of unknown intensity in all quadrants.
