NTSB narrative
The airplane had been airborne for about 5 minutes when the engine lost power. The pilot then force landed in a field, and the airplane nosed over. During a post-accident examination, the propeller was replaced, and the engine was started and operated for about 5 minutes at 1,700 rpm. The fuel system was also examined, and the fuel screens in both fuel tanks were found to be covered in a "fine muddy silt," consistent with mud dauber activity. A subsequent fuel analysis revealed that particulate contamination and gum levels were "very high." The fuel tanks had been open during the airplane's construction, and the airplane had about 30 hours of operation at the time of the accident.
Probable cause
The owner/builder's inadequate fuel tank inspection during construction, which resulted in fuel contamination and subsequent fuel starvation to the engine.

- 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.
