NTSB narrative
The pilot was flying over his mountainous ranch property to check on his cattle following a fire. When he did not return, the family reported him overdue. The wreckage was subsequently found on the ranch property at an elevation of about 7,115 feet mean sea level. The density altitude at ground level was estimated to be about 12,495 feet; the operating limitations for the airplane state that the maximum ceiling is about 14,000 feet pressure altitude at maximum weight. On-site wreckage documentation indicated that the airplane collided with terrain in a nearly vertical attitude. Because of the high density altitude on the day of the accident and the elevation of the terrain, the pilot had little altitude within which to operate before reaching the airplane's maximum ceiling. It is likely that, while maneuvering the airplane near or above the airplane's maximum ceiling, the pilot failed to maintain adequate airspeed, which resulted in a stall and a subsequent loss of control. A postaccident examination of the airframe and engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation.
Probable cause
The pilot's failure to maintain adequate airspeed while maneuvering at or above the airplane's maximum ceiling, which resulted in a stall and a subsequent loss of airplane control. Contributing to the accident was the pilot's decision to operate the airplane in the high density altitude conditions, which placed the airplane near or above its maximum ceiling.

- 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: investigation status, coordinates. Values present in the bulk record are kept.
- The date is the UTC date the NTSB stores; the local time zone is not recorded, so the local date may differ by a day.
