NTSB narrative
JUST AFTER MAKING THE INITIAL TAKEOFF CLIMB POWER REDUCTION THE PILOT NOTICED THAT THE ENGINE OIL PRESSURE WAS INDICATING ZERO. BEFORE HE COULD LAND AT HIS DEPARTURE AIRPORT THE ENGINE SEIZED. AN OFF AIRPORT FORCED LANDING RESULTED IN SUBSTANTIAL DAMAGE TO THE AIRPLANE. THE ENGINE OIL FILTER ADAPTER HAD SEPARATED FROM THE OIL PUMP HOUSING, AND ALL ENGINE OIL WAS LOST. THE THREADS ON THE ADAPTER AND HOUSING WERE WORN AND DAMAGED. THE ADAPTER HAD LAST BEEN INSTALLED USING WATER PUMP PLIERS INSTEAD OF THE SPECIAL WRENCH AS PER THE CESSNA MAINTENANCE MANUAL.
Probable cause
ENGINE FAILURE DUE TO TOTAL OIL LOSS. CONTRIBUTING TO THE ACCIDENT WERE THE SEPARATION OF THE OIL FILTER ADAPTER FROM THE OIL PUMP DUE TO IMPROPER MAINTENANCE PROCEDURES AND NON ADHERENCE TO RECOMMENDED DIRECTIVES BY COMPANY MAINTENANCE PERSONNEL, AND THE UNSUITABLE TERRAIN ON WHICH TO MAKE THE FORCED LANDING.

- 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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1992-06-19.
