NTSB narrative
While the pilot was maneuvering the airplane to set up a visual approach, the engine lost partial power. The pilot attempted to restore full engine power but was unsuccessful. Subsequently, he made a forced landing in a field, and the airplane nosed over. A postaccident examination of the engine revealed that it would only partially rotate by hand with resistance. Further examination revealed that the camshaft gear was missing nine teeth and that one tooth was damaged. The crankshaft gear was missing four consecutive teeth, and one tooth was missing from another location on the gear. A metallurgical evaluation of the camshaft gear, crankshaft gear, an exhaust valve, and a lifter revealed that the components met all the material properties requirements. The fracture surfaces on the camshaft and crankshaft gears were damaged due to post-separation contact. Debris from the oil sump was identified as nitrided gear material and lifter fragments. The engine had accumulated about 12 hours of operating time since its most recent inspection, which included an oil change. At the time of the accident, the engine had accumulated a total time of 750.7 hours. According to the owner and the engine maintenance log, no propeller strikes had occurred since the engine was installed on the airframe.
Probable cause
A loss of engine power due to the failure of the camshaft gear teeth and crankshaft gear teeth 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.
