00.2—APPLICATION.—The owner of any aircraft, who desires a registration certificate for the aircraft as an aircraft of the United States, shall make application therefor to the Secretary upon a form supplied for the purpose, which may be combined with the application for a certificate of airworthiness under CAR 01.

00.5—AS EVIDENCE.—For the purpose of exercising any privilege granted by any international convention, or of enforcing national laws, the registration certificate (or registration) will be deemed prima facie evidence of the nationality of the aircraft.
00.6—DURATION.—A registration certificate, when issued, will remain effective for an indeterminate time, or until
(a) the aircraft is no longer eligible for registration as an aircraft of the United States, or
(b) ownership of the aircraft is transferred, or
(c) registration of the aircraft is cancelled at the written request of the owner, or
(d) registration of the aircraft is suspended or revoked.
