NTSB narrative
The pilot maneuvered the twin-engine pressurized airplane to a level attitude about 18,000 feet mean sea level (msl). Approximately 30 minutes later, while approaching the downwind side of a ridge of mountains, the airplane entered an uncontrolled descent and impacted mountainous terrain. During the last radio transmissions from the pilot, he reported having serious difficulties; however, he was unsure of the exact nature of the problem. Following the loss of radar contact, a pilot from a passing airplane approached the accident area and located the wreckage. As the pilot circled the wreckage, he encountered a mountain wave event and elected to depart the area. A meteorological study of weather conditions in the accident area indicated the potential for severe mountain wave activity at the time of the accident. There were also numerous pilot reports specifically identifying encounters with mountain waves and/or severe or extreme turbulence at flight levels close to the accident area. A postaccident examination of the airplane revealed no anomalies that would have precluded normal operation.
Probable cause
The pilot's inadvertent flight into mountain wave activity resulting in a loss of control and subsequent impact with mountainous terrain.

Source notes (4)
- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2008-12-21.
