## Discrepancy

AFTER ROTATION, THE CREW FELT A VIBRATION COMING FROM THE NOSE GEAR.  THE CREW LOWERED THE GEAR ASSUMING THAT THERE WAS A BLOWN TIRE.  MAINTENANCE CONTROL REQUESTED FLIGHT 4169 CONTINUE TO PIT FOR MAINTENANCE BUT THE CREW FELT IT WOULD BE SAFER TO LAND BACK AT AZO.  THE CREW DECLARED AN EMERGENCY AND LANDED AT AZO WITH NO FURTHER INCIDENTS.  MAINTENANCE INSPECTED AND REPLACED THE NOSE WHEELS IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 32-00-00.  OPERATIONAL CHECKS WERE PERFORMED AND THE AIRCRAFT WAS RELEASED FOR SERVICE.
