## Discrepancy

PART IS LEAKING OIL. OIL SEAL HAD BECOME DISPLACED FROM FUEL PUMP DRIVE SEAL BORE IN ENGINE GEARBOX. OIL WAS COMING OUT OF THE FUEL PUMP CASE DRAIN, THROUGH THE DRAIN HOSE AND OUT OF THE DRAIN CLUSTER ON THE BELLY OF THE AIRCRAFT. FUEL PUMP WAS REMOVED, THE DRIVE SEAL WAS REPLACED WITH NEW SEAL AND THE FUEL PUMP WAS REINSTALLED.
