This advisory circular (AC) provides guidance and describes one method, but not the only method, for demonstrating compliance with §§ 23.907 and 25.907 of Title 14 of the Code of Federal Regulations (14 CFR) for the evaluation of vibratory stresses on propellers installed on airplanes. This evaluation uses fatigue and structural data obtained in accordance with 14 CFR part 35.

This advisory circular (AC) sets forth an acceptable means, but not the only means, for demonstrating compliance to the following by computer modeling analysis techniques validated by dynamic tests: • Title 14 Code of Federal Regulations (14 CFR) parts 23, 25, 27, and 29, §§ 23.562, 25.562, 27.562, and 29.562. • The Technical Standard Order (TSO) associated with the above regulations, TSO-C127/C127a.

Provides maintenance inspection notes which can be used for the maintenance support program for certain structural parts of the DC-8 series aircraft.

       b.  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). However, if you choose to use the means described in this AC follow it in its entirety. 

This advisory circular (AC) shows you how to obtain Federal Aviation Administration (FAA) airworthiness approval for the development, verification, and integration of an integrated modular avionics (IMA) system for installation into an aircraft or engine.  We cite RTCA, Inc. document RTCA/DO-297, Integrated Modular Avionics (IMA) Development Guidance and Certification Considerations, dated November 8, 2005 and supplement it with this text.  This AC also provides guidance on how to show compliance with Technical Standard Order (TSO)-C153, Integrated Modular Avionics Hardware Elements.

This AC is not mandatory and does not constitute a regulation.  In it, we describe an acceptable means, though it is not the only means, to obtain FAA approval of IMA systems.    

This AC uses the terminology “should” when discussing compliance to the AC itself, as the AC represents one, but not the only, method of complying with the regulations.   This AC uses the term “must” when discussing compliance to the regulations, as compliance to a regulation is not optional.  In these cases, the AC text supplies, in square brackets, a reference to the specific rule(s) being discussed.

This advisory circular (AC) provides guidance material on the installation of electronic flight bag (EFB) components including aircraft connectivity provisions.  In it, the Federal Aviation Administration (FAA) describes certification considerations for individual EFB components and for installing EFB aircraft connectivity provisions by addressing the principal elements, or “components,” which comprise a typical EFB device or system. 

This AC describes an acceptable means, but not the only means, to comply with Title 14 of the Code of Federal Regulations (14 CFR) part 23, 25, 27, or 29.  This AC is not mandatory and does not constitute a regulation.  However, if you use the means described in this AC, you must follow it entirely.  The term “must” is used to indicate mandatory requirements when following the guidance in this AC.  The terms “should” and “recommend” are used when following the guidance is recommended but not required to comply with this AC. 

This advisory circular (AC) gives you guidance for the fire-fighting effectiveness, selection and safe-use of hand fire extinguishers in airplanes and rotorcraft. In it we will also show you how to gain Federal Aviation Administration (FAA) approval of hand fire extinguishers for aircraft.
