## Narrative

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

(-23) THE AIRCRAFT WAS ENROUTE FROM SHERIDAN WY (KSHR) TO HAILEY ID (KSUN) AT APPROXIMATELLY 8500' AND 22 MILES SE OF HAILEY ID WHEN A MODERATE ENGINE VIBRATION WAS DETECTED BY THE PILOT.  WITHIN 2-3 MINUTES THE VIBRATION BECAME SEVERE AND THE PILOT DECLARED AN EMERGENCY TO THE HAILEY TOWER.  A LARGE VOLUME OF SMOKE WAS REPORTED COMING FROM THE LOWER ENGINE COWL.  THE AIRCRAFT LANDED ON RUNWAY 31 WITHOUT FURTHER INCIDENT.  UPON INSPECTION OF THE AIRCRAFT THE FOLLOWING DAMAGE WAS NOTED.  NUMBER 3 CYLINDER HAD SHEARED AWAY FROM THE ENGINE CASE, THE NUMBER 3 CONNECTING ROD WAS DISCONNECTED FROM THE CRANK SHAFT AND SEVERE DAMAGE TO THE ENGINE CASE WAS NOTED.  THE NUMBER 3 CONNECTING ROD CAP WAS RECOVERED.  ONE ROD BOLT SHOWED EVIDENCE OF DUCTILE OVERLOAD AND THE OTHER BOLT PULLED THROUGH THE RETAINING NUT WITH SEVERAL OF THE NUT THREADS STILL REMAINING ON THE BOLT.

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.
