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.

Guidelines for the Certification, Airworthiness, and Operational Use of Electronic Flight Bags
This joint Flight Standards Service (AFS) and Aircraft Certification Service (AIR) advisory circular (AC) contains guidance on the operational use of Electronic Flight Bags (EFBs). It is intended for all operators conducting flight operations under Title 14 of the Code of Federal Regulations (14 CFR) part 121, 125, 135, or 91 subpart F (part 91F) and part 91 subpart K (part 91K) who want to replace required paper information or utilize other select functions of an EFB. This AC sets forth an acceptable means, but not the only means, to obtain Federal Aviation Administration (FAA) authorization for the operational use of EFBs. Part 91 operators can find additional EFB information in the current edition of AC 91-78, Use of Class 1 or Class 2 Electronic Flight Bag (EFB). For guidance on the installation of EFB components, refer to the current edition of AC 20-173, Installation of Electronic Flight Bag Components.

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.

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.

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|
