## Discrepancy

(CAN) ON APPROACH NOSE LANDING GEAR DID NOT EXTEND.  CREW CARRIED OUT A GO-AROUND AND COMPLETED A MANUAL EXTENSION.  THE GEAR LOWERED AND LOCKED-CREW RECEIVED 3 GREENS IN THE COCKPIT.  THE AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE WAS DISPATCHED TO TROUBLESHOOT.  PSEU CODES READ AND FORWARDED TO TECH OPS.  AFTER CONSULTATION WITH TECH OPS, SUSPECT THE NLG SELECTOR VALVE AT FAULT.  AFTER FURTHER INSPECTION IT WAS NOTED THAT THE NLG SELECTOR VALVE HAD A SLIGHT LEAK NR THE SOLENOID CONNECTOR PLUG WAS CONTAMINATED WITH HYD FLUID.  THE SELECTOR VALVE WAS REPLACED AND GEAR SWINGS WERE CARRIED OUT WITH NFF AND A/C WAS RETURNED TO SERVICE WITHOUT ANY FURTHER INCIDENTS.  (TC NR 20070416005)
