NTSB narrative
The pilot was on a personal cross-country flight through a mountain pass. He later reported that upon reaching the pass, the terrain elevation was climbing faster than his airplane, and the weather in the pass was worse than expected. He then decided to turn the airplane around and exit the pass the way he had come. As he made the turn, the terrain continued to rise and it was apparent he wasn't going to make the turn, so he stalled the airplane while trying to out climb terrain. The airplane subsequently impacted terrain, sustaining substantial damage to the wings and fuselage. The pilot said there were no preaccident mechanical anomalies with the airplane that would have precluded normal operation.
Probable cause
The pilot's failure to maintain clearance from terrain while maneuvering to reverse course.

- 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 local date, which is the same as the UTC date the NTSB stores.
