## Discrepancy

THE A-SYSTEM HYDRAULIC QUANTITY DROPPED TO ZERO SHORTLY AFTER TAKEOFF.  THE FLUID LOSS WAS ACCOMPANIED BY ILLUMINATION OF THE NR 2 A-SYSTEM LOW PRESSURE LIGHT.  CHECKLIST PROCEDURES WERE COMPLIED WITH AND THE AIRCRAFT WAS RETURNED TO EWR WHERE IT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND THE A-SYSTEM FLEX LINE CHAFED THROUGH AT RT WING BETWEEN RT LANDING GEAR AND NR 2 ENGINE PYLON.  THE LINE WAS REMOVED AND REPLACED, THE HYDRAULIC SYSTEM WAS SERVICED AND OPERATIONAL AND LEAK CHECKS WERE GOOD.
