## Narrative

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

(-23) DURING AN INSTRUCTIONAL FLIGHT, THE INSTRUCTOR NOTICED A LOSS OF POWER IN MANUEVERING FLIGHT WITH THE POWER INITIALLY SET AT 21' MP AT 2200 RPM. AN INCREASE IN OIL TEMPERATURE WAS NOTED ALTHOUGH THE OIL PRESSURE REMAINED CONSTANT AND WITHIN NORMAL RANGES. THE A/C WAS TURNED BACK TO THE EUGENE, OREGON AIRPORT WHEN A SEVERE VIBRATION WAS EXPERIENCED AND THE ENGINE WAS SHUT DOWN TO PREVENT STRUCTURAL DAMAGE. AN EMERGENCY LANDING WAS PERFORMED TO THE GROUND IN A NEARBY HAY FIELD. THERE WAS NO DAMAGE TO THE A/C, AND NO INJURIES OCCURRED. FAA MAINTENANCE PERSONNEL INSPECTED THE ENGINE AND FOUND BEARING MATERIAL THROUGHOUT THE OIL SYSTEM. FURTHER INVESTIGATION REVEALED REAR MAIN BEARING FAILURE LEADING TO CRANKSHAFT FATIGUE SEPARATION AT THE NUMBER 4 CRANKSHAFT PIN.

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.
