## Discrepancy

(CAN) DURING THE APPROACH, THE NLG FAILED TO EXTEND UPON GEAR DOWN SELECTION AND THE CREW RECEIVED A GEAR DISAGREE WARNING MESSAGE.  THE GEAR SELECTOR WAS CYCLED SEVERAL TIMES WITHOUT SUCCESS.  THE LANDING GEAR MANUAL RELEASE HANDLE WAS PULLED AND ALL 3 GEARS EXTENDED.  THE ACFT LANDED WITHOUT FURTHER INCIDENT.  THE NOSE LANDING GEAR SELECTOR VALVE,  REF IPC 32-33-00-01-185B, WAS REPLACED, TESTED AND THE ACFT WAS RELEASED INTO SERVICE.
