## Discrepancy

AFTER TAKE-OFF,  THE AIRCRAFT RETURNED BACK TO THE AIRPORT DUE TO A LOUD NOISE HEARD AFTER GEAR RETRACTION. THE CREW FOLLOWED FLIGHT MANUAL INSTRUCTION AND LANDED WITH OUT INCIDENT.  AFTER LANDING THE FLIGHT CREW DISCOVERED THAT THE RT NOSE LANDING GEAR DOOR CENTER HINGE BRACKET HAD FAILED ALLOWING THE DOOR TO MOVE UNCONTROLLED.  MAINTENANCE REPLACED THE FORWARD AND AFT BRACKETS.  IT WAS UNDETERMINED WHAT CAUSED THE FAILURE OF THE NOSE GEAR DOOR BRACKETS.
