|120-73||ANM-100||Damage Tolerance Assessment of Repairs to Pressurized Fuselages Provides guidance to operators of certain transport category airplanes operated under 14 CFR Parts 91, 121, 125, and 129. The guidance provides an acceptable means of compliance with the regulations that require incorporating FAA-approved “repair assessment guidelines” into an operator’s FAA-approved maintenance or inspection program. The means of compliance described is intended to provide guidance to supplement the engineering and operational judgment that must form the basis of any compliance findings relative to repair assessments for pressurized fuselages.||12-14-2000|
|120-93||ANM-100||Damage Tolerance Inspections for Repairs and Alterations This advisory circular (AC) provides guidance material for Type Certificate (TC) Holders, Supplemental Type Certificate (STC) Holders, and operators to comply with requirements in the Aging Airplane Safety Act to ensure the airworthiness of aging airplane parts and components. The Aging Airplane Safety Rule that supports the Act specifies incorporating damage tolerance-based inspections into an operator’s continuous airworthiness maintenance program. These inspections will help ensure the integrity of fatigue critical structure on transport category airplanes operated in air transportation. This guidance will provide persons who have developed repairs and alterations with a means to develop damage tolerance data to be used to determine damage tolerance inspections for repairs and alterations that affect fatigue critical structure. This AC will give guidance on developing compliance documents, schedules and plans that will assist in developing and incorporating damage tolerance inspections into maintenance programs of certain transport category airplanes with respect to repairs and alterations.||11-20-2007|
Establishing and Implementing Limit of Validity to Prevent Widespread Fatigue Damage
This advisory circular (AC)offers guidance on compliance with Title 14 Code of Federal Regulations (14 CFR) 26.21, 26.23, 121.1115, and 129.115. It tells design approval holders of transport category airplanes how to establish a limit of validity of the engineering data that supports the structural maintenance program (hereafter referred to as LOV) for those airplanes. It also tells design approval holders how to address maintenance actions that have been determined necessary to support an LOV. It tells operators of those airplanes how to incorporate the LOV into their maintenance programs. Finally, this AC provides guidance to anyone wishing to extend an LOV. Guidance for establishing an LOV for airplanes whose type certificate was applied for after (XXXX) is contained in AC 25.571-1X. Guidance for extending an LOV approved under § 25.571, § 26.21, or § 26.23 can be found here. The actions described in this AC are meant to prevent widespread fatigue damage (WFD) in the transport airplane fleet up to the LOV.
|120-42B||AFS-220||Extended Operations (ETOPS and Polar Operations) States an acceptable means but not the only means for obtaining approval under FAR Section 121.161 for two-engine airplanes to operate over a route that contains a point farther than one hour flying time at the normal one-engine inoperative cruise speed (in still air) from an adequate airport.||06-13-2008|
Fatigue Risk Management Systems for Aviation Safety
(1) Describes the basic concepts of Fatigue Risk Management Systems (FRMS), as prescribed in Title 14 of the Code of Federal Regulations (14 CFR) part 117, § 117.7, and how they relate to aviation industry employees safely performing their duties.
(2) Provides information on the components of an FRMS as applied to aviation, and on how to implement an FRMS within an aviation operation.
(3) Defines an FRMS as an operator-specific process; therefore, while all FRMSs will have common elements, the specifics will be tailored to a certificate holder’s particular conditions.
(4) Provides (in Appendix 2, Fatigue Risk Management System Development) the certificate holder with the necessary detailed guidance to prepare for the FRMS approval process, develop the required documentation, develop and apply fatigue risk management (FRM) and Safety Assurance (SA) processes, collect and analyze data, develop flightcrew FRMS operations procedures and a step-by-step process required for Federal Aviation Administration (FAA) evaluation and validation of the proposed FRMS application.

Guidance for Conduction and Use of Flight Standardization Board Evaluations
a. Evaluating Manufactured or Modified Aircraft. It provides a means but not the only means of evaluating manufactured or modified aircraft by the use of standard systems, processes, and tests necessary to determine pilot training and qualification requirements.
b. Differences in Training and Qualification between Aircraft. It describes an acceptable means, but not the only means, of compliance with applicable Title 14 of the Code of Federal Regulations (14 CFR) that provide for differences in training and qualification between aircraft with the same type certificate. It further describes an acceptable means for providing related aircraft differences training and qualification under provision of 14 CFR part 121 between aircraft with different type certificates that have been "designated" by the Administrator as related. Both of these processes use the provision of the Flight Standardization Board (FSB) report as the basis for the approval of pilot training and qualification necessary for the operation of aircraft. This AC is intended to enhance safety by:
(1) Providing a standard method of assessing applicant programs.
(2) Directly relating pilot training and qualification requirements to fleet characteristics, operating concepts, and pilot assignments.
(3) Permitting better industry planning and management by outlining what FAA requirements apply, what training resources or devices are needed, and what alternatives are possible.
(4) Encouraging aircraft manufacturers to design with the goal of developing common characteristics between related aircraft
(5) Providing a recommended framework for application of suitable credits or constraints to better address new technology and future safety enhancements.

Incorporation of Fuel Tank System Instructions for Continued Airworthiness into Operator Maintenance or Inspection Programs
On May 7, 2001, the Transport Airplane Fuel Tank System Design Review, Flammability Reduction and Maintenance and Inspection Requirements final rule was published in the Federal Register (FR). It has since been referred to as the 2001 Fuel Tank Safety (FTS) rule. It adopted amendments to part 25, Special Federal Aviation Regulation (SFAR) 88 and operating requirements related to SFAR 88. The operating requirements included requirements to implement instructions for continued airworthiness (ICA) that design approval holders (DAH) developed in compliance with SFAR 88. On November 8, 2007, the Federal Aviation Administration (FAA) published the Enhanced Airworthiness Program for Airplane Systems (EAPAS)/FTS final rule. The purpose of the rule is to help ensure the continued safety of transport category airplanes by improving the design, installation, and maintenance of electrical wiring systems. The EAPAS/FTS rule amended the operating requirements to implement FTS actions developed in accordance with SFAR 88. Integrating the incorporation of the fuel tank system and electrical wiring interconnection system (EWIS) requirements helps to ensure compatibility and to eliminate duplication. Additionally, the EAPAS/FTS rule redesignates (replaces) Title 14 of the Code of Federal Regulations (14 CFR) part 91, § 91.410(b); part 121, § 121.370(b); part 125, § 125.248(b); and part 129, § 129.32(b) of the FTS rule. The new sections are §§ 91.1507, 121.1113, 125.507 and 129.113. These new rules also clarify language with reference to the approval process of the operator’s program. This advisory circular (AC) only addresses the fuel tank system safety requirements and describes acceptable means of compliance (AMC) accordingly. The current edition of AC 120-102, Incorporation of Electrical Wiring Interconnection Systems Instructions for Continued Airworthiness into an Operator’s Maintenance Program, addresses EWIS requirements in the EAPAS/FTS rule.
