14 CFR 215.5: Procedure in case of similarity of names.

The Department will compare the proposed name in any registration filed under this part or in an application for new, reissued, or transferred authority with a list of names used by existing certificated, commuter and foreign direct air carriers. The Department will notify the applicant of any other certificated, foreign or commuter carriers that may have an identical or similar name. The registrant must then notify those carriers of its registration. The notification will identify the applicant and state its proposed name or the name requested, area of operation or proposed area of operation, type of business, and other pertinent matters. The registrant must then file a certificate of service of the notification with the Department.
