## Discrepancy

(CAN) DURING FLIGHT, REPORTS OF FLUID LEAKING FROM THE NACELLE FUEL/OIL DRAIN OF NR 1 ENGINE PROMPTED THE CREW TO SHUT THE ENGINE DOWN.  NO COCKPIT INDICATIONS REPORTED. THE ACFT LANDED SINGLE ENGINE WITHOUT ANY FURTHER PROBLEMS.  POST FLIGHT INSPECTION FOUND A WORN AC GENERATOR DRIVE SHAFT PLAIN SEAL, POST SB21861, CAUSING AN OIL LEAK TO THE DRAIN.  THE ACFT HAS RETURNED TO OPERATION AFTER SEAL REPLACEMENT.
