14 CFR 215.4 - Change of name or use of trade name.
(a)Registrations. Any air carrier subject to this part that desires to change the name in which its operating authorization has been issued, or to use a trade name, or to obtain initial operating authority must register the name with the Department. The Department will construe any application for initial, reissued, or transferred authority as containing a “registration” of the intended name. A separate name registration document need not be filed. A carrier registering use of a trade name, without seeking reissuance of its underlying certificate commuter or foreign air carrier permit or exemption authority, must file a statement that complies with §§ 302.3 and 302.4 of this chapter registering its intended name with the Air Carrier Fitness Division if it is a U.S. certificated or commuter carrier, or within the Licensing Division if it is a foreign air carrier.
(b)Montreal Agreement. Each registration under this section shall be accompanied by three copies of a counterpart to the Montreal Agreement (Agreement 18900) (OST Form 4523) signed by the carrier using the proposed name. Upon arrival of the application, the Department will place a copy of the signed OST form 4523 in Docket 17325.
