## Discrepancy

THE ENGINE OIL LINE SUPPLYING OIL TO THE OIL COOLER BEGAN TO LEAK RAPIDLY IN-FLIGHT.  OIL PRESSURE WAS LOST, THE ENGINE WAS SHUTDOWN AND AN UNSCHEDULED LANDING WAS ACCOMPLISHED WITHOUT DAMAGE.  INSPECTION REVEALED THAT THE LOSS WAS FROM THE P/N AE7013002H0194 OIL HOSE, THE INTERNAL LINING APPEARED TO HAVE BEEN SOFTENED AND RIPPED SUCH AS POSSIBLY A COMPOUND THAT WAS NOT COMPATIBLE WITH THE 2380 ENGINE OIL.  FAILURE OCCURRED.
