## Discrepancy

THE B-SYSTEM HYDRAULIC QUANTITY DROPPED TO 1/2 ACCOMPANIED BY ILLUMINATION OF THE B-ENGINE HYDRAULIC PUMP LOW PRESSURE LIGHT WHILE EN ROUTE.  THE B-ENGINE HYDRAULIC PUMP WAS SHUT OFF AND THE AIRCRAFT WAS RETURNED TO IAH WHERE IT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND THE NR 2 ENGINE DRIVEN HYDRAULIC PUMP LEAKING AND THE FILTER HOUSING FOR ELECTRIC DRIVEN B-PUMP CRACKED.  THE NR 2 ENGINE DRIVEN HYDRAULIC PUMP AND B-SYSTEM FILTER WERE REMOVED AND REPLACED.  THE HYDRAULIC SYSTEM WAS SERVICED AND OPERATIONAL AND LEAK CHECKS WERE GOOD.
