## Discrepancy

(CAN) CREW ADVISED LOSS OF NR 2 HYDRAULIC PRESSURE IN CRUISE TO DESTINATION, ACTIVATING THE RUDDER HYDRAULIC ISOLATION SYS. MAINTENANCE ADVISED THAT THE LOSS OF NR 2 HYDRAULIC PRESSURE WOULD AFFECT NOSE WHEEL STEERING FOR THE LANDING.  CREW REQUESTED EMERGENCY VEHICLES TO BE ON STANDBY FOR THE LANDING AT THE DESTINATION. ACFT LANDED WITHOUT INCIDENT AND WAS TOWED FROM THE RUNWAY.  THE MAINTENANCE STAFF WAS ABLE TO DETERMINE THAT THE NR 2 ENGINE DRIVEN PUMP WAS LEAKING EXTERNALLY, CAUSING THE LOSS OF FLUID AND SUBSEQUENT LOSS OF PRESSURE. THE FAILED PUMP IS S/N MX426592D.
