## Discrepancy

GSO - FLT 1275 - THE A-SYSTEM HYDRAULIC QUANTITY DECREASED TO ZERO DURING CLIMB-OUT OF GSO.  THE FLUID LOSS WAS ACCOMPANIED BY ILLUMINATION OF THE A-HYDRAULIC SYSTEM LOW PRESSURE LIGHTS.  A MANUAL GEAR AND FLAP EXTENSION WAS PERFORMED AND THE AIRCRAFT WAS RETURNED TO GSO WHERE IT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND THE NR 2 ENGINE DRIVEN HYDRAULIC PUMP LEAKING.  THE NR 2 PUMP WAS REMOVED AND REPLACED.  THE HYDRAULIC SYSTEM WAS SERVICED TO FULL.  LEAK AND OPERATIONAL CHECKS WERE GOOD.  (X)
