NTSB narrative
DURING CRUISE FLIGHT, THE PILOT OBSERVED A LOSS OF OIL PRESSURE, ACCOMPANIED BY THE SMELL OF BURNING OIL. THE PROPELLER OVERSPED, AND THE ENGINE SUBSEQUENTLY QUIT. THE AIRPLANE WAS FORCE LANDED ON A GOLF COURSE, AND COLLIDED WITH TREES DURING THE LANDING ROLL. AN EXAMINATION OF THE ENGINE REVEALED THE THREADS ON THE OIL FILTER ADAPTER, AND THE MATING THREADS ON THE ENGINE CASE, WERE SEVERELY FRETTED, AND OIL HAD LEAKED OUT OF THE ENGINE, AROUND THE ADAPTER THREADS. THERE WAS EVIDENCE OF OIL STARVATION AND THERMAL DISTRESS ON INTERNAL ENGINE PARTS. EVIDENCE SUGGESTS THAT THE JAM NUT WHICH TIGHTENS THE ADAPTER TO THE ENGINE CASE EITHER LOST ITS PRELOAD TORQUE, OR WAS UNDERTORQUED DURING MAINTENANCE. LOGBOOK ENTRIES INDICATING THE LAST MAINTENANCE ON THE ADAPTER WERE NOT LOCATED.
Probable cause
A LOSS OF ENGINE POWER DUE TO OIL STARVATION. THIS RESULTED FROM AN UNDERTORQUED CONDITION OF THE OIL FILTER ADAPTER, AND THE SUBSEQUENT FRETTING OF THE ADAPTER THREADS.

- 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.
