## Discrepancy

THE CREW REPORTED ON APPROACH INTO KUGN THE LANDING GEAR HANDLE WAS SELECTED DOWN, BUT THERE WAS NO GEAR MOVEMENT.  NO PROBLEMS WERE NOTED WHEN THE CIRCUIT BREAKERS AND HYDRAULIC FLUID INDICATIONS WERE CHECKED.  AN EMERGENCY WAS DECLARED AND AN ALTERNATE GEAR EXTENSION WAS PERFORMED.  AN UNEVENTFUL LANDING WAS MADE IN KUGN AND CFR RESPONSE WAS GIVEN.  MAINTENANCE REPLACED THE LANDING GEAR SELECT / DUMP VALVE.  ALL OPERATIONAL AND LEAK CHECKS THAT WERE PERFORMED WERE SATISFACTORY.  THE AIRCRAFT WAS RETURNED TO SERVICE.
