## Discrepancy

DURING A SCHEDULED ZONE INSPECTION, THE MECHANIC FOUND THE CHIP DETECTORS FOR THE NR 2 ENGINE WITH SMALL AMOUNTS OF METAL CHIPS ON ALL DETECTORS.  HE THEN REMOVED THE OIL FILTER TO FIND METAL CHIPS AS WELL.  AN OIL SAMPLE AND CHIPS WERE SENT TO LAB FOR TESTING.  THE RESULTS WERE DETERMINED TO BE A BEARING IN THE M04 SECTION.  THE M03, M04 & M05 ENGINE MODULES AS WELL AS THE OIL PUMP ARE ALL CURRENTLY BEING REPLACED AT THE TIME OF THIS SUBMISSION.
