## Discrepancy

APPROXIMATELY 2 AND A HALF HOURS INTO CRUISE FROM TAPA TO FHAW, THE HYDRAULIC QUANTITY STARTED DECREASING.  THE CREW SWITCHED TO EMERGENCY, AND THE LOSS OF HYDRAULIC FLUID STOPPED.  LOSS OF HYDRAULIC FLUID CHECK LIST WAS COMPLIED WITH AND THE CREW RETURNED TO TAPA AND LANDED.  MAINTENANCE FOUND THE WHEEL BRAKE CONTROL VALVE LEAKING.  THE WHEEL BRAKE CONTROL VALVE WAS REPLACED AND THE LEAK CHECK WAS GOOD AND THE AIRCRAFT WAS RETURNED TO SERVICE.
