This advisory circular (AC) prescribes the procedures to develop and submit aircraft owner- and operator-specific inspection programs in accordance with an inspection program selected under the provisions of Title 14 of the Code of Federal Regulations (14 CFR) part 91, § 91.409(f)(4), and satisfies the requirements of § 91.409(g) for review and approval by the Federal Aviation Administration (FAA). This AC is not mandatory and does not constitute a regulation. This AC describes an acceptable means, but not the only means, to develop an Approved Inspection Program (AIP). However, if you use the means described in the AC, you must follow it in all important respects.

This AC is intended to provide guidance for developing maintenance and inspection programs for aircraft operated as public aircraft. The recommendations in this AC were developed using industry best practices, depending on the aircraft being operated. The AC describes methods for maintaining aircraft in order to maximize both a safety and economic benefit.

This AC provides guidance and standardized methods for meeting the training requirements outlined in Title 14 of the Code of Federal Regulations (14 CFR) Part 91 Subpart N, Mitsubishi MU-2B Series Special Training, Experience, and Operating Requirements, for Mitsubishi MU-2B aircraft. The new part 91 subpart N mandates training, experience, and operating requirements to ensure the highest level of operational safety for the Mitsubishi MU-2B series airplanes. This AC describes an acceptable means, but not the only means, of complying with the requirement that all training and checking for the MU-2B aircraft must be conducted in accordance with a Federal Aviation Administration (FAA)-approved training program. This AC is not mandatory and does not constitute a regulation; however, it may be used by training providers to meet the requirements of part 91 subpart N. Training providers may also use this AC as a reference for developing their own MU-2B training programs to submit for FAA approval pursuant to the requirements of part 91 subpart N.

This advisory circular (AC) provides guidance to persons operating UnmannedAircraft (UA) for hobby or recreation purposes meeting the statutory definition of "model aircraft" contained in Section 336 of Public Law 112-95, the FAA Modernization and Reform Act of 2012. This AC describes means by which model aircraft may be operated safely in the National Airspace System (NAS). Nothing in this AC changes the requirement to comply with the statute or any applicable regulations.

This advisory circular (AC) contains updated and additional information for the pilots of airplanes under Title 14 of the Code of Federal Regulations (14 CFR) parts 91, 121, 125, and 135. The purpose of this AC is to provide pilots with a convenient reference guide on the principal factors related to flight in icing conditions and the location of additional information in related publications. As a result of these updates and consolidating of information, AC 91-74A, Pilot Guide: Flight in Icing Conditions, dated December 31, 2007, and AC 91-51A, Effect of Icing on Aircraft Control and Airplane Deice and Anti-Ice Systems, dated July 19, 1996, are cancelled. This AC does not authorize deviations from established company procedures or regulatory requirements.

This advisory circular (AC) provides ways for pilots and airplane operators to identify, understand, and mitigate risks associated with runway overruns during the landing phase of flight. It also provides operators with detailed information that operators may use to develop company standard operating procedures (SOP) to mitigate those risks.

This advisory circular (AC) provides guidelines for the development and implementation of standard operating procedures (SOP) for conducting safe aircraft operations during taxiing to avoid causing a runway incursion. In accordance with the current edition of Federal Aviation Administration (FAA) Order 7050.1, Runway Safety Program, the definition of a runway incursion is, any occurrence at an aerodrome involving the incorrect presence of an aircraft, vehicle, or person on the protected area of a surface designated for the landing and takeoff of aircraft. This AC is intended for use by persons operating aircraft single pilot under Title 14 of the Code of Federal Regulations (14 CFR) parts 91 and 135, and flight schools. The FAA recommends that these guidelines become an integral part of all SOPs, Flight Operations Manuals (FOM), and formal flight training programs.

a.This advisory circular (AC) provides guidance on developing and implementing a Fatigue Management Program (FMP) to address in-service issues for metallic fatigue critical structure.  An applicant may develop an FMP as one method to address an unsafe condition when the Federal Aviation Administration (FAA) determines an airplane type design has a demonstrated risk of catastrophic failure due to fatigue.  In such cases, the FMP should incorporate damage-tolerance based inspections or a part replacement/modification program to mitigate the demonstrated risk.  The FMP should also incorporate other fatigue critical structure inspections to address the broader risk posed by potential cracking of these structures in the airplane.  The FAA will mandate the FMP by Airworthiness Directive (AD).  The FAA may also approve the FMP as an alternative method of compliance (AMOC) to an AD.

b.This AC includes guidance relevant to developing FMPs for other purposes such as life extensions, type certification requirements, or non-mandatory maintenance programs.  This guidance supplements other ACs that contain guidance for developing damage-tolerance based inspection programs to look proactively for potential cracks.  Such guidance includes AC 91?56B, Continuing Structural Integrity Program for Airplanes, AC 25.571?1D, Damage Tolerance and Fatigue Evaluation of Structure, and AC 23?13A, Fatigue, Fail-Safe, and Damage-Tolerance Evaluation of Metallic Structure for Normal, Utility, Acrobatic, and Commuter Category Airplanes.  Applicants should use product specific guidance in conjunction with this AC.

c.   This AC is not mandatory and does not constitute a regulation.  It describes an acceptable means, but not the only means, for maintaining the continued operational safety for airplane type designs that have a demonstrated risk.  In this AC, the FAA uses terms such as “must” or “require” only in the sense of ensuring applicability of a particular method of compliance when using a specific acceptable method of compliance described herein.

a. The Federal Aviation Administration (FAA) is amending its operating rules to require U.S. operators flying outside the United States to carry aircraft noise certification information on board the aircraft.

b. This Advisory Circular (AC) provides guidance to affected U.S. operators that operate aircraft outside the United States with aircraft that were never required to be noise certified. If you have such an aircraft, this AC outlines the noise certification requirement dates so you can confirm that your aircraft indeed pre-dates the requirements and should be considered acceptable. We use the term “grandfathered” for these aircraft. We strongly recommend operators of such aircraft to use the FAA form in Appendix 1 that includes a grandfather clause.

This advisory circular provides guidance to customers of the National Airspace System (NAS) in regard to the use of and participation on ATCSCC hotlines.

This advisory circular (AC) emphasizes the safety hazards of poorly maintained aircraft exhaust systems (reciprocating powerplants) and highlights points at which exhaust system failures occur. Further, it provides information on the types of problems to expect and recommends that pilots perform ongoing preventive maintenance and that mechanics perform maintenance.

This advisory circular (AC) suggests standards and procedures for the acquisition, use, and storage of pyrotechnic visual distress signaling devices that are intended for use in aircraft emergencies.
