NTSB narrative
The engine lost power during cruise flight at 1,800 feet msl and the airplane nosed over during an attempted forced landing in a field about 1/2 mile from the destination airport. Each fuel tank was at half capacity. Movement of the throttle valves inside the carburetors corresponded to movement of the throttle lever inside the cockpit. Operation of the primer button injected fuel into the carburetor intake body. The vacuum fuel pump was the primary feed for the engine. This pump could not be tested, as the engine could not be run. The electric fuel pump operated after vigorously cycling the master power switch several times between the on and off positions. The spark plugs were not wet with fuel or oil, and they exhibited characteristics of normal operation.
Probable cause
The engine lost power for undetermined reasons and nosed over in a soft field during the resulting forced landing.

- 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.
