## Discrepancy

DURING ROUTINE FLIGHT, LOUD NOISE WAS HEARD.  RT ENGINE WAS SHUT DOWN AND SECURED.  AFTER AN UNEVENTFUL LANDING, AN INSPECTION REVEALED A CATASTROPHIC CRANKCASE FAILURE AT THE NR 3 CYLINDER LOCATION HAD OCCURRED.  CYLINDER WAS COMPLETELY SEPARATE FROM CASE.  CASE WAS CRACKED AROUND BASE STUD AREA.  CAUSE WAS DETERMINED TO BE IN THE CRANKCASE ITSELF.  ENGINE HAD 217 HOURS SINCE OVERHAUL AND WAS RUNNING NORMAL WITH NO PROBLEMS REPORTED.
