## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

THE AIRCRAFT WAS IN CRUISE FLIGHT WHEN THE ENGINE LOST POWER AND THE OIL PRESSURE JUMPED UP AND DOWN ERRATICALLY.  THE PILOT INITIATED A TURN, AND HALF-WAY THRU THE TURN THE ENGINE COMPLETELY QUIT RUNNING.  THE AIRCRAFT WAS LANDED IN A BEAN FIELD.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
