## Discrepancy

THE RT HYDRAULIC SYSTEM QUANTITY DECREASED DURING CLIMBOUT.  QRH PROCEDURES WERE FOLLOWED FOR HYDRAULIC QUANTITY LOSS AND ALTERNATE GEAR EXTENSION WAS USED FOR RETURN TO MCO WHERE THE AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND THE RT INBOARD ANTI-SKID DUAL CONTROL VALVE LEAKING.  THE ANTI-SKID DUAL CONTROL VALVE WAS REMOVED AND REPLACED IAW MM 32-43-03, PAGE 202A.  LEAK AND OPERATIONAL CHECKS WERE GOOD.
