120-53B AFS-200 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.

120-16F AFS-300 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.

120-109 AFS-200 Stall and Stick Pusher Training

The information contained in this advisory circular (AC) was developed based on a review of recommended practices developed by major airplane manufacturers, labor organizations, air carriers, training organizations, simulator manufacturers, and industry representative organizations. This AC does not provide guidance for full aerodynamic stall training, which industry and government stakeholders are now developing. Once developed, this AC will be revised to include that guidance.

The goal of this AC is to provide best practices and guidance for training, testing, and checking for pilots, within existing regulations, to ensure correct and consistent responses to unexpected stall warnings and stick pusher activations. This AC emphasizes reducing the angle of attack (AOA) at the first indication of a stall as the primary means of approach-to-stall or stall recovery. Additionally, this AC provides guidance for operators and training centers in the development of stall and stick pusher event training.

120-98A AFS-300 Operator Information for Incorporating Fuel Tank Flammability Reduction Requirements into a Maintenance or Inspection Program

This advisory circular (AC) provides information and describes an acceptable means of compliance (AMC) with the Reduction of Fuel Tank Flammability in Transport Category Airplanes, final rule. It is commonly called the Fuel Tank Flammability Reduction (FTFR) rule. This AC describes acceptable means, but not the only means, for demonstrating compliance with the applicable regulations. The Federal Aviation Administration (FAA) will consider other methods of demonstrating compliance that an applicant may elect to present. While these guidelines are not mandatory, they are derived from extensive FAA and industry experience in determining compliance with the relevant regulations. If the FAA becomes aware of circumstances that convince us that following this AC would not result in compliance with the applicable regulations, the FAA may require additional substantiation or design changes as a basis for finding compliance. This material does not change or create any additional regulatory requirements, nor does it authorize changes in or permit deviations from existing regulatory requirements.

120-68F AFS-600 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.

120-97A AFS-300 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.

120-70B AFS-460 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.
