NTSB narrative
The pilot reported that during the initial climb the engine misfired and only produced "marginal power." As he executed a left turn back towards the airport, the engine lost power and he performed a forced landing onto a golf course. During the landing roll, the airplane struck a berm and became airborne again. Subsequently, the airplane landed hard and came to rest upright. Examination of the airplane by a Federal Aviation Administration inspector revealed that the airplane fuselage was structurally damaged. Examination of the converted Ford engine by the pilot revealed that the fuel system was intact and undamaged. The pilot also reported finding "no obvious" anomalies with the ignition system. The reason for the loss of engine power was not determined.
Probable cause
The 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.
