The recommendations contained herein are one means, but not the only means, of complying with § 91.21 requirements pertaining to the operation of PEDs.

(We list these operations in Paragraph 2.) We based these practices, in part, on National Transportation Safety Board (NTSB) safety recommendations.

This AC provides aircraft operator guidance on the use of radio frequency identification (RFID) devices and systems in operational and maintenance environments as a means of identifying or scheduling specific maintenance and inspection tasks in accordance with Title 14 of the Code of Federal Regulations (14 CFR) parts 43, 91, 121, 125, 129, and 135.

This AC describes methods the Administrator accepts per Title 14 of the Code of Federal Regulations (14 CFR) parts 21, 23, 25, 27, 29, 43, and 145 for the development, qualification, and approval of bias and radial aircraft tire retreads, their repair and process specifications, and the use of special nondestructive inspection (NDI) techniques.

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 is not mandatory and does not constitute a regulation.

1.Provides descriptions of references and training materials to ensure that thereader can assemble a Maintenance Human Factors (MxHF) training programmatched to the applicable needs of their specific organization. 2.Provides many sources of current information to develop, implement,reinforce, and assess MxHF training materials. 3.Streamlines MxHF training development at the local level. 4.Is not mandatory, like any AC, and does not constitute a regulation

Describes the basic concepts of human fatigue and how it relates to safety for aviation maintenance organizations and individual maintainers.

2. Provides information on Fatigue Risk Management (FRM) in terms of fatigue hazards and mitigation strategies specific to aviation maintainers.

There is no Title 14 of the Code of Federal Regulations (14 CFR) rule that specifically addresses aircraft ground handling, servicing, and marshalling; however, elements of these topics could be addressed under the following regulatory requirements: part 91, §§ 91.1073 and 91.1085; part 121, §§ 121.133, 121.135, and 121.137; part 135, §§ 135.21, 135.23, and 135.619 and appendix A; and part 139, § 139.329.

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.

The aim is to establish sufficient traceability to determine that the article(s) were manufactured under Title 14 of the Code of Federal Regulations (14 CFR) part 21, were previously determined to be airworthy under 14 CFR part 43, and were produced to established industry or U.S.

This advisory circular (AC) provides information and guidance concerning an acceptable means, but not the only means, of demonstrating compliance with the requirements of Title 14 of the Code of Federal Regulations (14 CFR) parts 21, 23, 25, 26, 27, 29, 31, 33, 35, 43, 91, 121, 125, 129 (U.S.-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).

For part 135 operations, this AC applies if you conduct your maintenance operations under part 135, § 135.411(a)(2). This AC also applies to each person employed or used by you as a part 119 certificate holder for any maintenance, preventive maintenance, and alteration of your aircraft.
