Incorporation of Fuel Tank System Instructions for Continued Airworthiness into Operator Maintenance or Inspection Programs (Including Change 1)
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.
Incorporation of Electrical Wiring Interconnection Systems Instructions for Continued Airworthiness into an Operator’s Maintenance Program (Including Change 1)
On November 8, 2007, the Federal Aviation Administration (FAA) published the Enhanced Airworthiness Program for Airplane Systems/Fuel Tank Safety (EAPAS/FTS) final rule. The intent of the rule is to help ensure the continued safety of commercial airplanes by improving the design, installation, and maintenance of electrical wiring systems. Title 14 of the Code of Federal Regulations (14 CFR) part 121, § 121.1111, and part 129, § 129.111 include requirements for operators to revise their maintenance programs to include instructions for continued airworthiness (ICA), which include inspections and procedures for the electrical wiring interconnection systems (EWIS). This advisory circular (AC) only addresses the EWIS requirements and provides guidance accordingly. The current edition of AC 120-97, Incorporation of Fuel Tank System Instructions for Continued Airworthiness into Operator Maintenance or Inspection Programs, provides guidance for operators to comply with the fuel tank safety (FTS) requirements in the EAPAS/FTS rule.
In-flight Radiation Exposure
This advisory circular (AC) provides basic background information and links to sources of more detailed information that can be used to improve air carrier programs that inform crewmembers about in-flight ionizing radiation exposure.
This advisory circular (AC) updates information regarding the hazards and risks of in-flight fires on transport category aircraft. The information includes recommended crewmember procedures and training for combating in-flight fires. The National Transportation Safety Board (NTSB) issued Safety Recommendations A-11-87 through A-11-91 during the investigation of United Parcel Service (UPS) flight 6 accident on September 3, 2010 in the United Arab Emirates. The flightcrew encountered a "Fire Main Deck" master warning about 22 minutes into the flight; they declared an emergency and initiated a return to Dubai International Airport (DXB). The aircraft crashed inside an Emirate army post 9 miles from DXB, and both flightcrew members were fatally injured. NTSB findings revealed safety issues related to the training and use of oxygen mask; communicating with oxygen masks donned; and oxygen mask stowage and the smoke, fire, or fumes checklists. This revision to AC 120-80 is in response to NTSB recommendations A-11-88 through A-11-90.

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).
Flightcrew Member Line Operational Simulations: Line-Oriented Flight Training, Special Purpose Operational Training, Line Operational Evaluation
This advisory circular (AC) presents guidelines for the design and implementation of Line Operational Simulations (LOS), including Line-Oriented Flight Training (LOFT), Special Purpose Operational Training (SPOT), and Line Operational Evaluation (LOE) for flightcrew members. This document does not interpret the regulations; interpretations are issued only under established agency guidelines. As operators develop LOSs, they should develop an interdependent relationship between their human factors, Crew Resource Management (CRM), flight operations, and safety initiatives, because they are linked to a common safety goal.
This AC describes a means by which LOS scenarios are developed, scripted, tested, evaluated, and (in the case of LOFT and LOE) approved by the Administrator for use in an operator’s training program. The methodology set forth also achieves the Federal Aviation Administration’s (FAA) mandate to ensure that each certificate holder provides the highest level of safety in the public interest, while meeting the agency’s responsibility to reduce or eliminate the possibility or recurrence of accidents in air transportation.
