## Discrepancy

MAINTENANCE NOTICED OIL LEAKING FROM #2 ENGINE COWLING.  INSPECTION REVEALED OIL LEAKING FROM THE SCAVENGE OIL PUMP HOUSING PINHOLE AND REPLACED HOUSING.  REMOVED UNIT WAS VERIFIED TO HAVE INTERNAL EROSION THROUGH BODY OF THE HOUSING.   THIS HAS BECOME A COMMON ISSUE AND PWC IS WORKING ON FIXING IT.
