## Discrepancy

PTY - FLT 0770 - THE A-SYSTEM HYDRAULIC LOW PRESSURE LIGHT FLICKERED ON AND OFF AFTER TAKEOFF AND WAS FOLLOWED BY LOSS OF THE A-SYSTEM HYDRAULIC QUANTITY.  THE AIRCRAFT WAS RETURNED TO PTY WHERE IT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND THE NR 2 ENGINE HYDRAULIC PUMP CASE SPLIT.  THE NR 2 HYDRAULIC PUMP WAS REMOVED AND REPLACED.  IN ADDITION, THE NR 1 ENGINE HYDRAULIC PUMP WAS REPLACED AS A PRECAUTIONARY MEASURE.  OPERATIONAL AND LEAK CHECKS AFTER HYDRAULIC SYSTEM SERVICING WERE GOOD.  (X)
