## Discrepancy

THE FLIGHT CREW REPORTED THAT DURING POST FLIGHT CHECKS HYDRAULIC FLUID LEAKING FROM BOTH SIDES OF THE VERTICAL STAB AND UNDERNEATH THE HORIZONTAL STAB.  THE MAINTENANCE VENDOR DISCOVERED THAT THE RUDDER SERVO ACTUATOR WAS LEAKING EXTERNALLY.  THE SERVO WAS REPLACED WITH A REPAIRED UNIT.  OPERATIONS AND LEAK CHECKS WERE SATISFACTORY.  THE AIRCRAFT WAS RETURNED TO SERVICE.
