## Discrepancy

CREW REPORTED THAT THERE WAS A LOUD NOISE COMING FROM THE NOSE LANDING GEAR DURING FLIGHT AND BELIEVED THAT THE LANDING GEAR DOORS DID NOT FULLY CLOSE.  ALL OF THE GEAR INDICATIONS WERE GOOD.  THE CREW SLOWED THE AIRCRAFT, CYCLED THE LANDING GEAR, AND THE NOISE STOPPED.  THE AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE REPLACED THE NOSE LANDING GEAR SEQUENCE SWITCH.  OPERATIONAL CHECKS WERE GOOD WITH NO FURTHER DEFECTS NOTED.
