## Discrepancy

NR 2 ENG MAIN OIL FILTER HAS METAL IN IT, AND OIL IS BLACK.  REPLACED THE MAIN OIL FILTER PER AMM 79-21-05.  ALL CHIP DETECTORS WERE CLEAN, AND THERE WAS NO EVIDENCE OF HYDRAULIC FLUID OR FUEL CONTAMINATION.  THE MAIN OIL FILTER WAS CHECKED 25 FLIGHT HOURS LATER, AND FOUND TO HAVE NO CONTAMINATION.
