Flight and Weather Briefing

During a weather briefing, the pilot received information that visual flight rules (VFR) flight was not recommended. The briefing also indicated that passes were closed, and two pilot reports stated that clouds extended to the ground near a pass.

Contact with Air Traffic Control

Subsequently, the pilot contacted Anchorage Approach Control, reporting that he was 73 miles north of Anchorage, intending to land. He requested traffic separation and radar vectors. Approach control responded that the pilot was too far north for radar coverage and advised him to maintain VFR conditions.

The wreckage was located at the 4,000-foot level of a 4,500-foot high ridge or mountain. This area is near where the minimum enroute altitude (MEA) or minimum obstruction clearance altitude (MOCA) changes from 10,000 feet to 7,500 feet southbound.
