## Discrepancy

OXC/BDL - EN ROUTE ON A PRE-POSITIONING FLIGHT, THE CREW REPORTED THE OIL PRESSURE STARTED TO DECLINE ON THE LEFT ENGINE.  AT 15 PSI, THE LEFT ENGINE WAS SHUT DOWN.  THE AIRCRAFT LANDED WITHOUT INCIDENT AT BDL.  AN INVESTIGATION REVEALED THAT OIL WAS LEAKING FROM THE CONNECTION AT THE CHECK VALVE, PN 3074372-1.  THE ENGINE WAS REMOVED, DETAILS WILL FOLLOW AS THEY BECOME AVAILABLE.
