## Discrepancy

CREW REPORTED THAT IN FINAL APPROACH, WHEN THE LANDING GEAR WAS LOWERED, THERE WAS A BANGING NOISE COMING FROM THE NOSE LANDING GEAR.  GEAR INDICATIONS SHOWED THE LANDING GEAR DOWN AND LOCKED.  AIR TRAFFIC CONTROL DECLARED AN EMERGENCY.  AIR TRAFFIC CONTROL CONFIRMED THAT THE LANDING GEAR WAS DOWN AND APPEARED TO BE LOCKED.  THE AIRCRAFT LANDED AND TAXIED TO THE GATE WITHOUT INCIDENT.  MAINTENANCE FOUND THE RIGHT-HAND MAIN LANDING GEAR DOWNLOCK PROXIMITY SWITCH TO BE LOOSE.  RESECURED THE PROXIMITY SWITCH.  OPERATIONAL CHECKS AND LANDING GEAR SWINGS WERE GOOD WITH NO FURTHER DEFECTS NOTED.
