## Discrepancy

THE NOSE GEAR UNSAFE LIGHT REMAINED ILLUMINATED AFTER GEAR RETRACTION LEAVING ATL.  CHECKLIST PROCEDURES WERE COMPLIED WITH AND THE AIRCRAFT WAS RETURNED TO ATL WHERE IT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND THE NOSE GEAR UPLOCK SENSOR AT FAULT.  THE SENSOR WAS REMOVED AND REPLACED.  THE NOSE GEAR WAS RETRACTED WITH OPERATION AND INDICATIONS CHECKING GOOD.
