NTSB narrative
The pilot reported that, during cruise flight, the engine began to run rough and he attempted to troubleshoot; shortly thereafter, oil pressure decreased to 0 and the engine began to vibrate before it lost all power. The pilot performed a forced landing, during which the airplane struck a ditch and nosed over, substantially damaging the left wing.
Examination of the engine revealed that the crankshaft was fractured in fatigue aft of the No. 3 connecting rod journal, adjacent to the counterweights. Both counterweights were in place and remained attached to the crankshaft. Detailed examination of the fractured crankshaft revealed some non-conformances in the geometric tolerances of several crankcase attributes, and polishing was observed on the crankcase saddle bore landings; however, none were deemed severe enough to cause the crankshaft to fail in the time and manner in which it occurred. The cause of the crankshaft failure could not be determined based on the available information.
Probable cause
The loss of engine power due to a fatigue failure of the crankshaft for reasons that could not be determined based on the available information.

- 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, cause areas. 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.
