NTSB narrative
While in cruise flight there was a loss of oil pressure resulting in a loss of engine power and seizure of the engine crankshaft. The airplane was damaged during a forced landing into a muddy agricultural field. Post-accident investigation of the engine revealed the number 5 connecting rod bearing had excessive clearance.
Probable cause
A loss of engine power due to excessive clearance of the connecting rod bearing resulting in engine seizure. A related factor was the muddy field.

- 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.
