## Discrepancy

RT ENG LOST POWER IN FLIGHT & ENDED UP SHUTTING IT DOWN.  THE ACFT LANDED WITHOUT INCIDENT.  UPON INSPECTION MX FOUND THE RT ENG CRANK CASE HAD BEEN PENETRATED.  INITIAL INVESTIGATION LEADS UP TO BELIEVE A CONNECTING ROD SEPARATED FROM THE CRANKSHAFT.  THE ENG HAS BEEN REMOVED & IS BEING SENT FOR TEARDOWN.
