## Discrepancy

AIRCRAFT LOST THE A-SYSTEM HYDRAULIC QUANTITY WHILE EN ROUTE.  THE LOSS WAS ACCOMPANIED BY ILLUMINATION OF THE NR 1 A-PUMP PRESSURE LIGHT.  THE HYDRAULIC QUANTITY LOSS AND HYDRAULIC SYSTEM FAILURE CHECKLISTS WERE ACCOMPLISHED AND THE AIRCRAFT LANDED AT IAH WITHOUT INCIDENT.  MAINTENANCE FOUND HYDRAULIC PRESSURE LINE AT A-SYSTEM PRESSURE MODULE LEAKING.  THE LINE WAS REPLACED USING FLEX LINE AND A DIP WAS ISSUED TO REPLACE THE FLEX LINE WITHIN 1200 HOURS OR 500 FLIGHTS.
