## Discrepancy

A FLIGHT WAS CANCELLED AFTER THE FLIGHT CREW WAS UNABLE TO START THE NR 1 ENGINE.  THE FLIGHT CREW PUSHED THE STARTER BUTTON AND NOTED NO ENGINE ROTATION.  THE MAINTENANCE VENDOR TROUBLE SHOT AND DETERMINED THAT THE NR 1 STARTER/GENERATOR WAS DEFECTIVE.  THE S/G WAS REPLACED WITH AN OVERHAULED UNIT.
