NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.
The flight was initially conducted on an instrument flight rules (IFR) flight plan above an overcast layer of clouds. As the pilot neared the destination airport, he was told by air traffic control (ATC) that there would be a delay in issuing the pilot a clearance for an approach due to other traffic in the area. The pilot elected not to wait. He requested and received vectors to an area of known visual conditions, and then reported that he saw a 'big hole' in the clouds. He canceled his IFR clearance and told ATC that he was going to initiate a circling descent to get underneath the clouds. The airplane dropped below ATC's radar coverage and the pilot was cleared to the destination via his own navigation. About 7 minutes later, the airplane impacted rapidly rising terrain that was shrouded in thick fog.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: The pilot's attempt to conduct visual flight into instrument meteorological conditions. A factor contributing to the accident was the presence of thick fog. Full narrative available
