## Discrepancy

CLT - FL846 - CREW DID NOT RECEIVE NOSE GEAR GREEN LIGHT UPON GEAR EXTENSION.  CREW RECYCLED THE GEAR AND ACCOMPLISHED A FLYBY OF THE TOWER WITH INCONCLUSIVE RESULTS.  CYCLED THE GEAR AGAIN BUT DID NOT RECEIVE NOSE GEAR GREEN LIGHT.  AIRCRAFT LANDED WITHOUT INCIDENT AND TAXIED OFF RUNWAY.  MAINTENANCE REPLACED A SHORTED UPLOCK SENSOR, REPLACED THE PROXIMITY CONTROL UNIT AS PRECAUTIONARY, AND SWUNG THE GEAR.  (M)
