## Discrepancy

THE AIRCRAFT LOST A-SYSTEM HYDRAULIC PRESSURE AND QUANTITY DURING CLIMBOUT.  THE AIRCRAFT WAS RETURNED TO EWR WHERE IT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND AN A-SYSTEM HYDRAULIC PRESSURE LINE CRACKED.  THE HYDRAULIC LINE WAS REMOVED AND REPLACED.  IN ADDITION, THE NR 1 ENGINE DRIVEN HYDRAULIC PUMP WAS REMOVED AND REPLACED.  LEAK AND OPERATIONAL CHECKS WERE GOOD.
