Incident Details
While descending to Richlands Airport, the pilot canceled the IFR flight plan and continued the flight under visual flight rules (VFR) in marginal weather conditions. Approximately one minute later, the twin-engine airplane struck the slope of an obscured mountain ridge and crashed. All three occupants were killed.
Investigation
Investigators determined the probable cause of the accident to be a controlled collision with ground due to improper IFR operation. Contributing factors reported in the official findings included low ceiling, fog, and the absence of a published instrument approach at the destination airport.
Conclusion
The accident highlights the risks associated with canceling an IFR flight plan and continuing VFR in deteriorating weather conditions, particularly when terrain is obscured and no instrument approach is available at the destination. The official findings cite the pilot's improper IFR operation as the primary cause, with environmental factors contributing to the outcome.
