## Discrepancy

THE B-SYSTEM HYDRAULIC QUANTITY WENT TO ZERO WHILE EN ROUTE TO MCO.  THE AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND THE HYDRAULIC FLEX LINE FROM ACOUSTIC FILTER TO B-HYDRAULIC PRESSURE MODULE CHAFED.  THE LINE WAS REMOVED AND REPLACED.  THE HYDRAULIC SYSTEM WAS SERVICED AND LEAK CHECKS WERE GOOD.
