This advisory circular (AC) provides all aircraft operators with information and guidance for assistance in compliance to Title 14 of the Code of Federal Regulations (14 CFR) part 39, Airworthiness Directives. The recommendations contained in this AC are one means, but not the only means, of complying with part 39 requirements pertaining to Airworthiness Directives (AD). However, individual operations and needs should determine an operator’s AD management process. When developing an AD management process, operators should consider their size, capabilities, resources, and equipment.

20-141B AIR-130 Airworthiness and Operational Approval of Digital Flight Data Recorder Systems

This advisory circular (AC) provides guidance on compliance with the applicable Regulations for the airworthiness and operational approval for digital flight data recorder systems (DFDRS).

This advisory circular (AC) provides information on certification (design and installation) and continued airworthiness of digital flight data recorder systems (DFDRS). DFDRS provide information for an investigative authority—the National Transportation Safety Board (NTSB) in the United States—to conduct more thorough investigations of accidents and incidents. The data recorded is also used by operators to enable the prediction of trends that may be useful in determining modifications needed to avoid accidents and incidents.

This AC provides information to applicants for a supplemental type certificate (STC), and to individuals who are responsible for establishing and maintaining compliance under the operating rules for digital flight data recorders (DFDR). Aircraft manufacturers who intend to install DFDRs in newly manufactured aircraft could also use this information.

This AC is not mandatory and is not a regulation. This AC describes an acceptable means, but not the only means, to comply with Title 14 of the Code of Federal Regulations (14 CFR).

20-171 AIR-120 Alternatives to RTCA/DO-178B for Software in Airborne Systems and Equipment

On January 11,1993, we, the Federal Aviation Administration (FAA), published Advisory Circular (AC) 20-115B recognizing RTCA/DO-178B, Software Considerations in Airborne Systems and Equipment Certification, dated December 1, 1992, as a means, but not the only means, to seek FAA approval of airborne software. RTCA/DO-178B is recognized by industry and certification authorities as an accepted approach for assuring that software in airborne systems and equipment has been developed to meet the safety objectives of the regulations.

 

This AC identifies what you, as an applicant, will have to address and document when you propose an alternative approach to that defined in RTCA/DO-178B. This AC is intended to provide you, the applicant, with guidance on how to establish that your proposed alternative provides the same level of assurance as that provided in RTCA/DO-178B for airborne software.  Your proposed alternative should be evaluated in conjunction with the certification process and applied to airborne systems and equipment (containing software) for which you are seeking FAA approval in order to obtain a Type Certificate, Supplemental Type Certificate, Amended Type Certificate, or Amended Supplemental Type Certificate.

This guidance also applies to the above articles, but does not include all requirements for testing the article, when part of 1090 megahertz (MHz) Extended Squitter (ES) or Universal Access Transceiver (UAT) Automatic Dependent Surveillance-Broadcast (ADS-B) systems. 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. Where indicated, this AC ensures compliance with regulatory requirements. Operators may elect to follow an alternative method that the Federal Aviation Administration (FAA) has found acceptable.

90-89B AFS-350 Amateur-Built Aircraft and Ultralight Flight Testing Handbook

This advisory circular (AC) provides suggestions and safety related recommendations primarily to assist amateur and ultralight builders in developing individualized aircraft flight-test plans. It also provides guidance for experimental light sport aircraft flight testing after modifications to the aircraft. It provides recommendations and suggestions you can combine with other sources on test flying, such as the aircraft plan/kit manufacturer’s flight testing instructions and other flight testing data. This will help you develop a detailed flight-test plan, tailored for your aircraft and resources.

This AC attempts to make you aware that test flying an aircraft is a critical undertaking, which you should approach with thorough planning, skill, and common sense. The flight-test plan is the heart of all professional flight testing. The plan should account for every hour spent in the flight-test phase and you should adhere to it with the same respect for the unknown that all successful test pilots share. The time allotted for each phase of a personalized flight-test plan may vary, and each phase may have more events or checks than suggested in this AC, but your goals, should be the same. You should add flight-test operational and performance data to the aircraft’s flight manual so you can reference the data prior to each flight.
