Fatigue Management Programs for Airplanes with Demonstrated Risk of Catastrophic Failure Due to Fatigue
a. This advisory circular (AC) provides guidance on developing and implementing a Fatigue Management Program (FMP). An applicant may develop an FMP as one method to address the unsafe condition that arises when the Federal Aviation Administration (FAA) has determined an airplane type design has an unsafe condition associated with a demonstrated risk of catastrophic failure due to fatigue (hereinafter referred to as demonstrated risk). An FMP incorporates damage-tolerance based inspections or a part replacement/modification program to mitigate the demonstrated risk. An FMP also incorporates inspections based on service history and engineering judgment to address the broader risk posed by potential cracking of other fatigue critical structure in the airplane. The FAA may mandate an FMP by Airworthiness Directive (AD) only in cases in which the FAA has determined that airworthiness action is necessary to address an unsafe condition. The FAA may also approve an FMP as an alternative method of compliance (AMOC) to an AD. b. This AC provides guidance for actions once the FAA determines that an AD is necessary to address the unsafe condition associated with a demonstrated risk. Existing FAA guidance supports development of damage-tolerance based inspection programs for transport category airplanes to look proactively for potential cracks. Such guidance includes AC 91-56B, Continuing Structural Integrity Program for Airplanes, and AC 25.571-1C, Damage Tolerance and Fatigue Evaluation of Structure. These existing ACs do not describe all the actions that should be used to address a demonstrated risk. 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. However, if you use the means described in this AC, you must follow it in all important aspects. In this AC, we use terms such as “must” or “require” only in the sense of ensuring applicability of a particular method of compliance when you use a specific acceptable method of compliance described herein.
Fatigue Management Programs for In-Service Issues
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.

Guidance on Carrying Noise Certification Documents On Board Aircraft Operating Outside the United States
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.

Reporting of Laser Illumination of Aircraft
a. This Advisory Circular (AC) provides information to the aviation community, particularly aircrews operating within the National Airspace System (NAS) on measures taken by the Federal Aviation Administration (FAA) to address incidents of unauthorized illumination of aircraft by lasers. The FAA Modernization and Reform Act of 2012, passed into public law on February 14, 2012, established a prohibition against aiming a laser pointer at an aircraft.
b. In addition, this AC provides guidance to aircrews and reflects current guidance for air traffic control (ATC) on the formal reporting of laser illumination incidents. Reporting laser incidents assists law enforcement and provides support for recommended mitigation actions to be taken to ensure continued safe and orderly flight operations.
c. This AC is issued in serious response to the significant increase of unauthorized laser illumination of aircraft incidents, as well as the proliferation and increased sophistication of laser devices available to the general public and other parties. FAA and other governmental studies show the exposure of aircrews to laser illumination may cause hazardous effects (e.g., distraction, glare, afterimage, flash blindness, and, in extreme circumstances, persistent or permanent visual impairment), which could compromise safety by adversely interfering with the ability of aircrews to carry out their responsibilities. ATC regards a laser illumination incident as an in-flight emergency, and will treat them as such, until the aircrew states otherwise.
d. The FAA, in coordination with local law enforcement, the Federal Bureau of Investigation, and other governmental agencies, such as the Department of Homeland Security, Transportation Security Administration (TSA), is taking immediate action to safeguard flights against these unauthorized illuminations and expeditiously locate the source of unauthorized laser transmissions.
