## Discrepancy

(CAN) AFTER FLIGHT MAINTENANCE NOTICED AN OIL LEAK FROM THE NR 2 NACELLE, FURTHER INVESTIGATION FOUND THE NR 2 AC GENERATOR SHAFT SHEARED. THE FLIGHT CREW HAD NOT NOTICED ANY FAILURES SINCE IN THE NORMAL OPERATION MODE THIS AC GEN IS IN STANDBY AND ONLY WORKS IF AN OTHER GEN FAILS. THE GEN WAS REMOVED AND THE AIRCRAFT RETURNED TO SERVICE.
