NTSB narrative
The pilot reported that no engine issues were detected during the run up. He stated that, during the takeoff, the climbout engine power was "good." On the turn to downwind, the pilot noticed a slight loss of engine power. He checked the throttle position and continued the downwind leg. The pilot considered landing on the crosswind runway but felt he had engine power to make a short 180° approach to the departure runway. During the turn to final, the engine had an additional power drop, "clattered" about 3-4 seconds, and subsequently stopped. The pilot landed straight ahead in a field, where the airplane nosed over and sustained substantial damage. A disassembly of the engine revealed that the camshaft was fractured in the area abeam the No.1 cylinder. The No. 1 connecting rod end was separated from its crankshaft journal, and the rod end exhibited discoloration consistent with lubrication distress. The liberated sections of connecting rod bearing material were found in the oil sump an exhibited discoloration consistent with lubrication distress. The oil transfer tube orifice for the No. 1 connecting rod bearing was smeared over with migrated connecting rod journal material. The migrated and smeared metal was drilled through to see if any debris was present; only metallic particles were present that were attracted by a magnet. No other blockages were found within the oil system. Scoring consistent with hard particle passage was observed within the oil pump housing. The oil filter was cut open and had one spot of dark-colored debris; no other debris found within the filter pleats. The oil suction pickup tube was disassembled and did not contain any debris. The No. 1 connecting rod end separation is consistent with oil starvation at the rod end.
Probable cause
The loss of engine power after the No. 1 connecting rod end separated as a result of oil starvation, which led to the forced landing and nose-over.

- 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.
