## Discrepancy

THE NR 1 HYDRAULIC SYSTEM FLUID QUANTITY DROPPED STEADILY DURING FLIGHT TO EWR.  THE AIRCRAFT LANDED AT EWR WITHOUT INCIDENT.  MAINTENANCE FOUND THE NR 1 LT ENGINE DRIVEN HYDRAULIC PUMP LEAKING.  THE HYDRAULIC PUMP WAS REMOVED AND REPLACED.  THE HYDRAULIC SYSTEM WAS SERVICED TO FULL.  LEAK AND OPERATIONAL CHECKS WERE GOOD.
