NTSB narrative
When the pilot failed to return from a local flight a search was initiated and the aircraft was found about 3 miles southeast of the departure airstrip. The aircraft collided with near level desert terrain at a 45-degree angle with no signs of rotation. The engine and accessories were examined and determined to be free of discrepancies. One propeller blade exhibited signs of rotation. A tachometer needle imprint was found about 975 rpm. An unquantified amount of fuel was present in the left wing fuel tank. The fuel system was approved for and operating on automobile gasoline. Internal fuel hose deteoriation was present obstructing a fuel sight gauge vent line and coupling hoses. Minor contamination was present in the fuel gascolator bowl along with a rust-colored water line. The aircraft was being operated without the front seat. Both rear seat belt attach points (.090 steel wire around 4130 steel tubing) had separated. No shoulder harness was installed.
Probable cause
The pilot's failure to maintain control of the aircraft for undetermined reasons.

- 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.
