What was found
WHILE EN ROUTE ON A ROUTINE FLIGHT, THE PILOT NOTICED OIL LEAKING FROM THE RIGHT ENGINE. THE AIRCRAFT DIVERTED TO AWN WHERE UPON INSPECTION IT WAS DISCOVERED THAT THE OIL COOLER OUTLET LINE P/N (AEROQUIP 950012-4-0090) HAD A SMALL HOLE DUE TO CHAFING WHICH WAS POSSIBLY CAUSED BY A BROKEN CLAMP P/N MS 21919DG10 WHICH ALLOWED THE LINE TO CHAFE AGAINST THE INTAKE TUBE. A NEW LINE WAS INSTALLED, OIL FILTER WAS INSPECTED FOR METAL, ENGINE WAS RUN AND LEAK CHECKED. NO LEAKS WERE NOTED. AIRCRAFT WAS THEN RELEASED FOR FURTHER FLIGHT. (IT SHOULD BE NOTED THAT THE OIL LEVEL WAS ONLY DOWN BY 2.5 QUARTS).
