This advisory circular (AC) provides information and guidance on developing procedures for part marking and part re-marking when performing maintenance, alteration, and fabrication, including the fabrication of owner- or operator-produced parts.

-registered airplanes), 133, 135, 137, and 145 regarding procedures and facilities for repairs and alterations of structures consisting of adhesively-bonded (including metal bond) and fiber-reinforced materials (e.g., carbon, aramid, and glass-reinforced polymeric materials mentioned in the current edition of AC 20-107, Composite Aircraft Structure).

Like all advisory material, this AC is not in itself mandatory and does not constitute a regulation. It provides a means, but not the only means, of testing at the time of original installation, after performing repairs, or during scheduled recertification.

The repair data may also be used as approved data, and the AC chapter, page, and paragraph listed in block 8 of FAA form 337 when:

a.

Review Title 14 of the Code of Federal Regulations (14 CFR) regarding engine records and standards.

Provides guidance material which may be used to determine the adequacy of barometers used in the calibration of aircraft static instruments and presents information concerning the general operation, calibration, and maintenance of such barometers.

Provides guidance regarding test cell correlation procedures for test cells used for in-service acceptance testing of turbofan and turbojet engines. This AC discusses the effects of the design, operation, and modification of a test cell and engine test hardware on engine performance.

AC contains acceptable methods, techniques, and practices for inspection, prevention, control and repair of corrosion on avionic systems and equipment.

This AC also provides information that can help determine if a proposed repair/alteration requires approved data, guidance and standardized procedures for obtaining field approval (or approval by other means) of data, and instructions for completing the field approval checklist.

Describes methods, procedures and practices determined to be acceptable for showing compliance with the general aviation maintenance record-making and record-keeping requirements of Title 14 of the Code of Federal Regulations (14 CFR) parts 43 and 91.

Additionally, this AC discusses the responsibilities and means of compliance for the air carrier and persons performing maintenance.

Provides guidelines concerning environmental conditions for instrument repair and overhaul shops and information on calibration of test equipment.

This advisory circular (AC) is for the development of inspection program requirements for the certification of former military aircraft in the experimental category for the purpose(s) of exhibition and air racing that operate in the United States in accordance with Title 14 of the Federal Code of Regulations (14 CFR) part 21, § 21.191(d) and (e).

This AC provides guidance to aircraft operators and maintenance, repair, and overhaul (MRO) organizations for the development of a corrosion control program.

This advisory circular (AC) provides information relating to the Bilateral Aviation Safety Agreement (BASA) and accompanying Maintenance Implementation Procedures (MIP) between the United States and Canada.

This AC provides one means of complying with the requirements of Title 14 of the Code of Federal Regulations (14 CFR) parts 21 and 43 for the design and fabrication of parts by persons performing maintenance and alterations using methods, techniques, and practices acceptable to the Administrator.

This advisory circular (AC) provides information concerning preventive maintenance,including who may perform it, the standards of performance applicable to it, authority for approval for return to service, and the applicable recording requirements. This AC clarifies those areas most frequently misunderstood in the past.

This advisory circular (AC) recommends an inspection schedule for owners of Daher (Socata) TBM Series aircraft. If aircraft owners/operators and maintenance providersinspect aircraft under a progressive inspection program, this AC will help ensure they comply with Title 14 of the Code of Federal Regulations (14 CFR) part 91, § 91.409.
