21.173, 21.175, 21.177, 21.179, 21.181, 21.191, 21.193, and 21.195; FAR Part 43, Appendix D; FAR Part 65, Sections 65.1, 65.11, 65.12, 65.13, 65.15, 65.16,

4. RELATED MATERIAL. AC 20-27C, Certification and Operation of Amateur-Built Aircraft. Copies of this AC may be obtained by writing to the U.S. Department of Transportation, Utilization and Storage Section, M-443.2, Washington, DC 20590.

5. BACKGROUND.

a. Previously, experimental aircrait certificates were effective for l year after the date of issuance or renewal, unless a shorter period was prescribed by the Administrator of the Federal Aviation Administration (FAA). Under the amended provisions of FAR Section 21.181(a) (3), effective September 10, 1979, experimental certificates ișsued to aircraft for the purpose of exhibition, air racing, or operating amateur-built aircraft have an unlimited duration unless the Administrator finds that a specific period should be established. Thus, performance of recertification inspections on these aircraft by FAA inspectors are no longer required. However, inspectors will continue to perform original certification inspections of experimental aircraft and construction inspections of amateur-built aircraft, amateur-built exhibition aircraft, and air racing aircraft.

b. In conjunction with amended FAR Section 21.181(a) (3), a new FAR Section 65.104, Repairman Certificate (experimental aircraft builder) - Eligibility, Privileges, and Limitations, was added to FAR Part 65. This section provides that a qualified builder of each exhibition, air racing, and amateur-built aircraft may be certificated as a repairman and would be privileged to perform condition inspections in accordance with FAR Part 43, Appendix D. However, aircraft manufacturing companies who produce experimental aircraft are not eligible for repairmen certificates.

c. When provided by the aircraft operating limitations, exhibition, air racing, and amateur-built aircraft may be inspected (condition inspections) by FAA-certificated mechanics holding an airframe and powerplant rating or FAA- certificated and appropriately rated repair stations, in accordance with FAR Part 43, Appendix D.

6. ELIGIBILITY. An individual desiring to be certificated as a repairman is required to:

a. Make application for a repairman certificate (experimental aircraft builder) at the time of original certification of the aircraft. Builders who have had their aircraft certificated prior to the effective date (September 10, 1979) of revised FAR Section 21.181(a)(3) and new FAR Section 65.104 may make application for repairman certification prior to the next condition inspection due date.

b. Be a U.S. citizen or an individual of a foreign country who has been admitted for permanent residence in the United States.

c. Be 18 years of age or older, and the primary builder of the aircraft.

For example, when a school, club, or partnership builds an aircraft, only one individual will be considered for a repairman certificate for each aircraft built, such as the class instructor or designated project leader.

d. Demonstrate to the certificating FAA inspector his or her ability to perform condition inspections and to determine whether the subject aircraft is in a condition for safe operation.

Note: The eligibility requirements of FAR Section 65.104 are in no way associated with those eligibility requirements for repairmen shown in FAR Section 65.101, titled "Eligibility Requirements:

General."

• PRIVILEGES AND LIMITATIONS. Holders of repairman certificates (experimenta aircraft builder) may perform "condition inspections" on specific aircraft built by the certificate holder. Consistent with FAR 65.104(b), the aircraft will be identified by make, model, and serial number as shown on the repairman certificate. During the aircraft certification procedure, the FAA issues operating limitations, as necessary per FAR Section 91.42, to ensure an adequate level of safety. These limitations may require that the subject aircraft be inspected annually by a repairman (experimental aircraft builder), the holder of an FAA mechanic certificate with appropriate ratings (airframe and powerplant), or an appropriately rated FAA repair station. Condition inspections will be performed in accordance with the scope and detail of FAR Part 43, Appendix D.

Operating limitations will also require that an appropriate entry be made in the aircraft maintenance records to show performance of this inspection.

Note: It should be noted that the privileges and limitations of FAR Section 65.104 are not associated with those privileges and limitations of FAR Section 65.103, titled Repairman Certificate:

Privileges and Limitations."
