(a) An experimental certificate shall emain in effect for one year from the ate of issuance or renewal, unless a horter period is established by the Adinistrator.

(b) The Administrator may, from me to time, reinspect any aircraft or art thereof to ascertain whether it is in irworthy condition. The owner, opertor, or bailee of the aircraft shall, upon equest, make it available for such inpection.

(c) Upon suspension, revocation, or ermination by order of the Administraor of an experimental certificate, the wner, operator, or bailee of an aircraft hall, upon request, surrender the cerficate to an authorized representative 7 the Administrator.

Amdt. 1-1, 21 F. R. 2585, Apr. 20, 1956] 1.75-1 Duration of experimental airworthiness certificate (FAA policies which apply to § 1.75).

(a) Experimental airworthiness cercates will be issued to expire on a ecific date, or will indicate a condi

tion under which the certificate will automatically expire. The duration of the experimental certificate may vary from one flight to a limited number of operating hours, or days. In any case, the duration will not exceed one year.

(b) It is the policy of the FAA to do everything possible to encourage legitimate experimentation leading to improvement in aircraft whenever this may be done without endangering the lives of persons or property not involved in the experimentation. Since it is recognized that a certain amount of danger to the operator is inherent in all experimental flying, the certificates issued for experimental aircraft will contain specific operating conditions and limitations designed to protect the lives and property of persons not involved in the experimentation.

[CAM 1 Rev., 21 F. R. 8809, Nov. 14, 1956] § 1.76 Special flight permits.

A special flight permit may be issued for an aircraft which may not currently meet applicable airworthiness requirements, but which is capable of safe flight, for the purpose of permitting the aircraft to be flown to a base where repairs or alterations are to be made, or to permit the delivery or export of the aircraft, or to permit production flight tests of new production aircraft.

§ 1.76-1 Special flight permits (FAA interpretations which apply to § 1.76).

(a) General. Section 43.10 (a) of this subchapter states in part that "No aircraft, except foreign aircraft authorized by the Administrator to be flown in the United States, shall be operated unless an appropriate and valid airworthiness certificate or special flight authorization and a registration certificate issued to the owner of the aircraft are carried in the aircraft *

"Special flight authorization," mentioned above, is interpreted to mean the special flight permit described in this section. Special flight permits are issued for only two purposes: the first and primary purpose is to permit aircraft not fully complying with the established airworthiness requirements to be flown to bases where repairs or alterations may be made; the second purpose is to permit "flyaway" delivery or flights to points of export of

aircraft which are airworthy but not eligible for a U. S. Certificate of Airworthiness. For example, an aircraft purchased by a person other than an American citizen would not be eligible for a U. S. Certificate of Airworthiness due to the fact that a current U. S. Registration Certificate is a prerequisite to obtaining an airworthiness certificate, and only a U. S. citizen, who can present proof of ownership, may obtain a current Aircraft Registration Certificate. [CAM 1 Rev., 21 F. R. 8809, Nov. 14, 1956]

§ 1.77 Special flight permits; requirements for issuance.

The requirements for the issuance of special flight permits are as stated in paragraphs (a) and (b) of this section.

(a) Where found necessary by the Administrator, an applicant for a special flight permit shall submit a statement in a form approved by the Administrator indicating the purpose of the flight, the proposed itinerary, the duration of authorization requested, the persons to be on board the aircraft, the particulars, if any, in which the aircraft does not comply fully with the applicable airworthiness requirements, and the restrictions, if any, deemed necessary for safe operation of the aircraft.

(b) The Administrator shall accomplish, or shall require the applicant to accomplish, such appropriate inspections or tests as the Administrator may deem necessary in the interest of safety.

(c) Nothing in paragraphs (a) and (b) of this section shall prevent the issuance to an air carrier by the Administrator of a general authorization to conduct ferry flights for specified purposes as provided in those paragraphs, under such terms and conditions as may from time to time be prescribed by the Administrator.
