NTSB narrative
AS THE PILOT LEVELED OFF AT HIS INTENDED CRUISE ALTITUDE, HE NOTED A LOSS OF OIL PRESSURE, THEN SAW OIL SPREAD UP OVER THE WINDSHIELD, RESTRICTING HIS VISIBILITY. THE PILOT PERFORMED EMERGENCY PROCEDURES, AND BEGAN DESCENDING TO THE NEAREST AIRPORT. DURING THE EMERGENCY DESCENT THE ENGINE SEIZED. THE PILOT WAS UNABLE TO REACH THE AIRPORT AND DESCENDED THROUGH SOME TREES BEFORE MAKING A FORCED LANDING IN A BEAN FIELD APPROXIMATELY 1/4 MILE FROM THE AIRPORT. THE LOSS OF OIL WAS DETERMINED TO BE DUE TO A CRACKED PROPELLER GOVERNOR OIL TUBE THROUGH WHICH OIL WAS PUMPED OVERBOARD.

- 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.
