NTSB narrative
The pilot reported that the engine was running good during the run up and takeoff but climb was slow. Without warning, the engine began sputtering and the pilot was able to keep the engine running with the primer for a short time. The pilot initiated a forced landing to a field where during the landing roll, the airplane was substantially damaged. Post-accident inspection of the engine found that a non-approved cork type material gasket was used around the gascolator that had disintegrated and plugged the fuel line. After the material was removed, the engine was run under normal operating conditions.
Probable cause
A blocked fuel line due to a gasket that had disintegrated and blocked the fuel line.

- 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.
