## Discrepancy

(CAN) ON APPROACH, THE TWO MLGS FAILED TO EXTEND UPON GEAR DOWN SELECTION AND THE CREW RECEIVED A "GEAR DISAGREE" WARNING MESSAGE. THE FLIGHT CREW EXECUTED A GO AROUND, LOWERED THE GEARS USING THE ALTERNATE HANDLE AND LANDED WITHOUT FURTHER INCIDENT.  THE MLG SELECTOR VALVE WAS REPLACED, TESTED BY MAINTENANCE AND THE ACFT WAS RELEASED FOR SERVICE.
