## Discrepancy

(CAN) THERE WAS SIGNIFICANT DROP IN HYDRAULIC QUANTITY FROM THE UTILITY SYSTEM IN-FLIGHT.  PER THE CHECK LIST THE PUMPS WERE OFF LOADED.  RE-ENGAGING THE PUMPS PRIOR TO LANDING, THE NR 2 UTILITY SYSTEM DID NOT COME BACK ON LINE.  LOSS OF ALL HYDRAULIC SYSTEMS.  NR 1 PRESSURE DURING LANDING ROLL RESULTED IN LOSS OF NOSE WHEEL STEERING.  MAINTENANCE WAS CALLED AND THE AIRCRAFT WAS TOWED TO THE GATE.  INSPECTION FOUND NR 2 UTILITY PUMP LEAKING BADLY FROM THE SHAFT SEAL.  THE PUMP WAS REPLACED.  THE SYSTEM REPLENISHED, CHECKED SERVICEABLE, AND THE AIRCRAFT RETURNED TO SERVICE.
