## Narrative

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

NARRATIVE: WHILE ON DESCENT TO LEWISTON, IDAHO, THE PILOT REPORTED TO LWS ATCT THAT THE ENGINE BEGAN RUNNING ROUGH AND OIL WAS EVIDENT ON THE COWLING. SMOKE WAS ENTERING THE COCKPIT AND SHORTLY THEREAFTER THE ENGINE STOPPED AND AN EMERGENCY LANDING WAS COMPLETED IN A FIELD ADJACENT TO POLK AIRPORT. SUBSEQUENT FIELD INSPECTION REVEALED THAT THERE WERE TWO HOLES IN THE ENGINE CASE. ONE LOCATED BETWEEN CYLINDERS 1 & 2 AND ANOTHER BETWEEN CYLINDERS 5 & 6. THE ENGINE STILL HAD A SUFFICIENT AMOUNT OF OIL IN THE ENGINE CASE. THERE WAS NO INJURY TO THE OCCUPANTS OR DAMAGE TO THE AIRCRAFT.

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.
