NTSB narrative
The pilot was on a cross-country flight, operating on a VFR flight plan. According to radar data, the airplane was following the apparent area of a highway and railroad track over mountainous terrain near Cumbres Pass. The highway went over the pass at 10,200 feet msl. Subsequently, the aircraft impacted the side of a mountain at an elevation of about 10,000 feet, approximately 1/2 mile from the top of the pass. The surrounding mountains were higher than the elevation of the crash site. There was evidence the pilot had entered instrument meteorological conditions (IMC). A railroad maintenance crew, working at the top of Cumbres Pass during the morning of the accident, noted low clouds and rain during the entire time, and reported the visibility was less than 1/4 mile at the pass.
Probable cause
flight by the pilot into instrument meteorological conditions (IMC), and his failure to maintain sufficient altitude and/or clearance from mountainous terrain. Factors relating to the accident were: the low ceiling, rain, fog, and high/mountainous terrain.

- 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. 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.
