NTSB narrative
The airplane sat for approximately one month prior to the accident flight with its wing fuel tanks about one-quarter full. Prior to the accident flight, the pilot's preflight inspection included sumping the fuel tanks and he thought he had removed all of the water and rust flake contamination from the fuel tanks. During takeoff, about 40 feet above the ground, the engine began to run rough. The pilot attempted a 180-degree turn back to the airport; however, the airplane impacted a field west of the airport and came to rest inverted. A postaccident examination of the wreckage revealed that fuel sumped from the fuel tanks contained a small amount of rust particles and debris consistent with an airplane being in an accident. No contamination of the fuel was noted in the gascolator and the gascolator screen was clean. The fuel line from the gascolator to the carburetor was clear. The finger screen from the carburetor contained a few rust particles, but not enough to affect fuel flow. The carburetor contained a small amount of fuel in the bowl, with no contamination noted. No other anomalies were observed that would have precluded the engine from developing full power. Additionally, the weather conditions at the time of the accident were not conducive to carburetor ice at takeoff power settings.
Probable cause
A partial loss of engine power during initial climb 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.
