## Discrepancy

DURING INTERNAL INSP OF ENG, A PIECE OF PLASTIC WAS FOUND IN THE OIL GALLEY BORE UNDER A NOZZLE.  THIS PIECE OF PLASTIC WAS LARGE ENOUGH TO COMPLETELY BLOCK OIL PASSAGE AT THE NOZZLE SCREEN.  THIS IS THE ONLY OIL SUPPLY TO THE MAIN PROPELLER SHAFT BEARING PN 3102885-1. THE PIECE OF PLASTIC COULD NOT PASS THROUGH THE OIL FILTER THERFORE MUST HAVE BEEN INTRODUCED DURING AN OIL FILTER REPLACEMENT. THE OIL FILTERS ARE WRAPPED IN PLASTIC TO KEEP THEM CLEAN AND SOMEHOW A PORTION OF PLASTIC WAS INTRODUCED DURING AN OIL FILTER REPLACEMENT.
