91-82A ACE-100 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.

61-91J AFS-800 WINGS - Pilot Proficiency Programs

 The objective of the WINGS Pilot Proficiency Program is to reduce the number of accidents in General Aviation (GA) by assisting airmen to find educational opportunities designed to help them apply the principles of risk assessment and risk management (RM). When properly applied, these principles will help mitigate accident causal factors associated with common pilot errors, lack of proficiency, and faulty knowledge. The Federal Aviation Administration’s (FAA) purpose is to encourage the majority of GA pilots, through WINGS, to engage in ongoing, targeted flying tasks and learning activities keyed to identified risks and which are designed to mitigate those risks. The FAA continually collects and assesses its databases to identify the risks associated with GA flying and incorporates risk mitigation strategies into initial and ongoing pilot education.
