|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.

Pilot Records Improvement Act of 1996
The Pilot Records Improvement Act of 1996 (PRIA), as amended, was enacted to ensure that air carriers and air operators adequately investigate a pilot’s background before allowing that pilot to conduct commercial air carrier flights. Under PRIA, a hiring employer cannot place a pilot into service until he or she obtains and reviews the last 5 years of the pilot’s background and other safety-related records as specified in PRIA.
This advisory circular (AC) is supplemented by the current edition of Federal Aviation Administration (FAA) Order 8000.88, PRIA Guidance for FAA Inspectors, and numerous other documents found on the PRIA Web site at http://www.faa.gov/pilots/lic_cert/pria. These sources of detailed information related to PRIA provide invaluable assistance to the certificate holder or others concerning the PRIA request process as well as other compliance issues.
The FAA has greatly expanded this AC from the previous version to address operational situations that the hiring employer may encounter that could affect his or her records request process through PRIA.
The Flight Standards Service (AFS) is committed to a stakeholder-driven system of operation that will deliver FAA records and assistance to all parties subject to PRIA, when necessary.
Operational Authorization Process for use of Data Link Communication System
This advisory circular (AC) presents various methods for operators of different data link systems to meet international standards set by the International Civil Aviation Organization (ICAO) and the regional airspace authorities. The Federal Aviation Administration (FAA) notes that there is presently no requirement in Title 14 of the Code of Federal Regulations (14 CFR) to have data link communications when operating in the National Airspace System (NAS). Instead, the regulations in 14 CFR govern radio communication systems, and nothing in this AC relieves an operator from the requirement to have and use a voice communication system when operating in international airspace or the NAS. However, operators that choose to operate in a reduced separation standard that requires the use of a data link system (in addition to the required voice communication system) must obtain FAA design approval and a revision to their 14 CFR part 121, 125, 125M, or 135 operation specifications (OpSpecs), part 91 subpart K (part 91K) management specifications (MSpecs) or part 91 letter of authorization (LOA), as applicable. The original AC 120-70 was applicable to Aeronautical Telecommunication Network (ATN), very high frequency (VHF) data link (VDL) Mode 2 communication systems. The Future Air Navigation System (FANS) 1/A system used in oceanic and remote airspace is an analog system which communicates over Aircraft Communications Addressing and Reporting System (ACARS). Guidance is needed for the operation of all systems and therefore the first revision AC 120-70A, was created.
Foreign Terminal Instrument Procedures (FTIP) Acceptance/Review
This advisory circular (AC) establishes guidelines for U.S. operators to use when reviewing Foreign Terminal Instrument Procedures (FTIP). Occasionally, the author uses the word "must" or similar language when he deems the desired actions critical. The Federal Aviation Administration (FAA) does not intend for the use of such language to add to, interpret, or relieve a duty imposed by Title 14 of the Code of Federal Regulations (14 CFR).

Air Carrier Maintenance Programs
This advisory circular (AC) explains what the term "maintenance program" means. Our explanation describes the scope and content of air carrier aircraft maintenance programs. This is important as there is a significant difference between an air carrier maintenance program and an inspection program used in non-air carrier maintenance operations. We explain the background of these programs as well as the Federal Aviation Administration’s (FAA) regulatory requirements. We also describe and explain each of the 10 elements of air carrier maintenance programs. When we use "must" or "will" in this AC, we are referencing actual regulatory requirements. When we use "we," "us," or "our" in this AC, we mean the FAA. When we use "you," "your," or "yours," we mean you, the air carrier. When we use the term "person," it has the same meaning as that in Title 14 of the Code of Federal Regulations (14 CFR) part 1, § 1.1.
