## Discrepancy

MAINTENANCE WAS CARRYING OUT A 7 DAY CHECK ON AIRCRAFT WHEN NOTICED SIGNS OF OIL LEAKING IN THE AFT SECTION OF THE NR 2 ENGINE.  ON INVESTIGATION, THE OIL WAS FOUND TO BE LEAKING PAST THE OIL INLET COVER FOR THE NR 5 BEARING AREA.  THE COVER WAS FOUND TO HAVE SCORING ON THE INTERIOR SMALL RADIUS.  THE COVER WAS REPLACED WITH A SERVICEABLE UNIT.  THIS SAME ITEM WAS REPLACED FOR A SIMILAR PROBLEM IN JULY 2005.
