a. This advisory circular (AC) identifies RTCA Document No. (RTCA/DO)-160 versions D, E, F, and G, Environmental Conditions and Test Procedures for Airborne Equipment, dated July 27, 1997, December 20, 2005, December 6, 2007, and December 8, 2010, respectively, as containing acceptable environmental qualifications to show compliance with certain airworthiness requirements. The FAA strongly encourages the use of RTCA/DO-160G for new articles.

b. Appendix 1 of this AC provides a summary of the changes from RTCA/DO-160C to RTCA/DO-160D, version D to E, version E to F, and F to G. The information in the table will assist you in determining if a particular version of RTCA/DO-160 is acceptable.

Provides information and guidance concerning and acceptable means, but not the only means, of demonstrating compliance with the requirements of FAR Part 21, Certification Procedures for Products and Parts, regarding quality control (QC) systems for the manufacture of composite structures involving fiber reinforced materials, e.g., carbon (graphite), boron, aramid (Kevlar), and glass reinforced polymeric materials. Provides guidance regarding the essential features of QC systems for composites as mentioned in AC 20-107.

 This advisory circular (AC) provides updated information and guidance to the aviation community for detecting suspected unapproved parts (SUP) and reporting them to the Federal Aviation Administration (FAA). Appendix 1 contains FAA Form 8120-11, Suspected Unapproved Parts Reports, which serves as a standardized means of reporting.

This advisory circular (AC) provides information for production approval holders (PAH) under Title 14, Code of Federal Regulations (14 CFR) part 21, Certification Procedures for Products, Articles, and Parts. This AC guides PAHs in developing and maintaining quality systems for the products and articles they produce. This guidance aids the applicant for a production approval or current PAH in developing a quality system that both meets the needs of the PAH and is compliant with the regulations. You can find this AC at http://www.faa.gov/regulations_policies/advisory_circulars/.

This advisory circular (AC) provides information about Title 14, Code of Federal Regulations (14 CFR) part 21, Certification Procedures for Products, Articles, and Parts. The AC covers subpart L, Export Airworthiness Approvals. This AC is not mandatory and does not constitute a regulation. This AC describes an acceptable means, but not the only means, to comply with these requirements. However, if you use the means described in the AC, you must follow it in all important respects.

This advisory circular (AC) provides guidance for creating a complete data package when data is submitted to a Federal Aviation Administration (FAA), aircraft certification office (ACO) or to FAA designees, to support a major repair or major alteration.

This AC provides information and guidance on developing procedures for using electronic modeling systems in design, manufacture, installation, and inspection processes.  It applies to applicants for Type Certificates (TCs), Amended Type Certificate (ATCs), Supplemental Type Certificates (STCs), Parts Manufacturer Approval (PMA), Technical Standard Order Authorizations (TSOA), major alterations, and major repairs.  In this AC, we explain how you can submit a proposal to use electronic modeling system data instead of (or in addition to) traditional paper format for the technical data required for initial and post certification activities.  We identify the minimum criteria for using electronic type design data, and include requirements for how to access and present the data.  In this AC, we define an “electronic modeling system” as a three?dimensional (3-D) modeling system.

 For Federal Aviation Administration (FAA) certification applicants, this AC mirrors our procedures in Order 8000.79, Use of Electronic Technology and Storage of Data, and Guide FAA-IR-01?01A, Aircraft Certification Guide for the Use of Electronic Technology and Alternative Methods of Storing Information. This AC must be used in conjunction with Order 8000.79 and Guide FAA-IR-01-01A.

 This AC is not mandatory and does not constitute a regulation.  We describe acceptable means, though it is not the only means, for using electronic modeling systems in design, manufacture, installation, and inspection processes.  If you use the means described in this AC, you must follow it in its entirety

We, the Federal Aviation Administration (FAA), wrote this advisory circular (AC) to describe how to comply with the requirements of Title 14 of the Code of Federal Regulations (14 CFR) 21.20, 21.97 and 21.303(a)(5). 
 This AC is not mandatory and is not a regulation.  This AC describes an acceptable means, but not the only means, to comply with the requirements 14 CFR 21.20, 21.97 and 21.303(a)(5).  However, if you use the means described in this AC, you must follow it entirely
