## Discrepancy

DURING CLIMB THROUGH FL380 A LOUD THUD WAS HEARD IN WHEEL WELL FOLLOWED BY LANDING GEAR UNLOCK LIGHT.  AN EMERGENCY WAS DECLARED AND DIVERTED TO KMCO.  ON DESCENT AT FL200 THE LANDING GEAR UNLOCK LIGHT EXTINGUISHED. ON APPROACH WHEN GEAR SELECTED TO DOWN POSITION, LANDING GEAR EXTENDED NORMALLY WITH 3 GREEN DOWN AND LOCKED INDICATORS. LANDING WAS UNEVENTFUL.  MAINTENANCE REPACKED THE NOSE LANDING GEAR STRUT.  GEAR SWINGS WERE PERFORMED NO DEFECTS NOTED.  A SUCCESSFUL OPERATIONAL CHECK FLIGHT WAS PERFORMED. AIRCRAFT WAS RETURNED TO SERVICE.
