NTSB narrative
Upon reaching a cruise altitude of 3,000 feet, the engine began to run rough and make loud noises. The flight instructor assumed control of the airplane, and the engine subsequently lost all power. Oil was present on the windscreen. The instructor performed a forced landing in a nearby field where the nose gear contacted a ditch, resulting in a nose over and substantial damage to the airframe. Initial examination of the engine revealed a hole on the lower case and the camshaft partially protruding from the upper case. Suspecting a failure of the No. 4 piston, it and cylinder were subsequently examined; all fracture surfaces showed signs of overstress; however, there was no indication of preexisting mechanical damage that would have led to progressive failure, including fatigue. No corrosion or chemical degradation was found on the piston fracture surfaces. Accordingly, the initiating event that led to the catastrophic failure of the engine could not be determined.
Probable cause
A total loss of engine power due to a catastrophic engine failure, the origin of which could not be determined during postaccident examination.

- 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.
