NTSB narrative
About 15 minutes after takeoff, during cruise flight, the pilot observed the engine oil pressure drop and the temperature increase, followed by a total loss of engine power. The pilot made an intentional gear-up forced landing on rough terrain. A partial teardown examination of the engine revealed ferrous and non-ferrous metal in the oil screens. The number 3 connecting rod was found bent, and the number 4 and number 5 cylinders were damaged. Numerous pieces of metal were observed in the crankcase that were associated with the number 4 and number 5 cylinders and pistons. The internal engine component that initially broke at the beginning of the sequence was not identified.
Probable cause
A total loss of engine power during cruise flight due to an undetermined catastrophic internal engine failure.

- 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.
