What was found
DURING OPERATIONS, AN OIL ODOR WAS NOTICED IN THE COCKPIT WITH BLEEDS SELECTED ON. OIL LEVELS IN BOTH ENGINES AND THE ACM UNIT WERE CHECKED AND FOUND TO BE GOOD. BOTH ENGINE NACELLES WERE INSPECTED FOR EVIDENCE OF OIL LEAKS, WITH NONE BEING FOUND. ENGINES WERE RUN ON THE GROUND WITH BLEEDS SELECTED ON WITH NO ODORS BEING DETECTED. THE AIRCRAFT WAS THEN RELEASED FOR SERVICE.
