20-53C AIR-600 Protection of Aircraft Fuel Systems Against Vapor Ignition Caused by Lightning

This advisory circular (AC) provides applicants with guidance for obtaining Federal Aviation Administration (FAA) approval of compliance pursuant to title 14, Code of Federal Regulations (14 CFR) 23.954, 27.954, and 29.954, Fuel system lightning protection. This AC recommends how to protect an aircraft’s fuel system from lightning strikes that may ignite fuel vapors.

For guidance on compliance pursuant to 14 CFR 25.954, Fuel system lightning protection, for transport category airplanes, see AC 25.954-1, Transport Airplane Fuel System Lightning Protection, dated September 6, 2018 (83 FR 47548, September 20, 2018).

This AC is not mandatory and does not constitute a regulation. This AC describes an acceptable means, but not the only means, to obtain certification for fuel system lightning protection. However, if you use the means described in this AC, you must follow it in all important respects. The term “must” is used to indicate mandatory requirements when following the guidance in this AC. The term “should” is used when following the guidance as recommended, but not required to comply with this

25.954-1 AIR-600 Transport Airplane Fuel System Lightning Protection
This advisory circular (AC) provides guidance for showing compliance with the airworthiness regulations for transport category airplanes regarding lightning protection of fuel tanks and systems. These lightning protection requirements apply to normal conditions and possible failures of fuel tank structure and systems that could lead to fuel tank explosions. This AC also provides guidance for developing critical design configuration control limitations (CDCCLs) and Airworthiness Limitations required to be included in the Instructions for Continued Airworthiness (ICA) related to lightning protection features of the airplane fuel system.

This AC provides guidance for showing compliance with § 25.981, which provides the certification requirements for the prevention of ignition sources, other than lightning, within the fuel tanks of transport category airplanes. (AC 25.954-1 addresses ignition sources due to lightning.) This AC includes guidance for prevention of failure conditions created from ignition sources other than lightning. It describes a means of compliance, using circuit protective devices such as an arc fault circuit breaker (AFCB) or ground fault interrupter (GFI), to provide fail-safe features that have been accepted as showing compliance with § 25.981.

61-136B AFS-800 FAA Approval of Aviation Training Devices and Their Use for Training and Experience This AC provides information and guidance for Aviation Training Device (ATD) manufacturers seeking Federal Aviation Administration (FAA) approval of a basic aviation training device (BATD) or advanced aviation training device (AATD) under Title 14 of the Code of Federal Regulations (14 CFR) part 61, § 61.4(c). This AC also provides information and guidance for those persons who intend to use a BATD or AATD for activities involving pilot training and experience, other than for practical tests, aircraft-type-specific training, or an aircraft type rating. This AC contains specific procedures regarding the evaluation, approval, and use of an ATD under 14 CFR parts 61 and 141. The criteria specified in this AC are used by the FAA to determine whether an ATD is qualified for approval as a BATD or an AATD. These guidelines have developed from extensive FAA and industry experience in determining methods of compliance with the pertinent 14 CFR regulations. Applicable regulations are noted only for reference. This AC does not change regulatory requirements; therefore, the provisions of the current regulation always control. This AC applies only to the evaluation and use of BATDs and AATDs. This notice does not apply to full flight simulators (FFS) and flight training devices (FTD) that are regulated under 14 CFR part 60. 09-12-2018

121-40 AXH-1 14 CFR Part 121 and Part 135 Dangerous Goods Transportation Operations

This Advisory Circular (AC) provides certificate holders with recommended contents for a dangerous goods training program and manual designed to guide and manage dangerous goods operations. Developing and using the comprehensive guidance in this document will promote the establishment of a safe and efficient dangerous goods operation. This AC establishes guidance for all part 119 certificate holders operating in accordance with part 121 or part 135 under operations specifications (OpSpec) to carry dangerous goods (Will Carry), prohibiting the transport of dangerous goods (Will Not Carry) and/or authorized to transport passengers and their baggage. Specifically, this AC sets forth suggestions for establishing a comprehensive dangerous goods training program and manual, regardless of the certificate holder’s OpSpec.

Dangerous goods are known to have been involved in, and the cause of, incidents and accidents associated with air transportation. A certificate holder’s dangerous goods program constitutes the foundation for safely transporting dangerous goods by air. This AC provides guidance on designing and implementing a dangerous goods program to include managing the risks entering the aviation system from declared and undeclared dangerous goods. Passengers and shippers of cargo routinely introduce hazards associated with dangerous goods into the air transport system, often unknowingly. This includes dangerous goods associated with baggage, cargo, and COMAT. Improperly prepared and mismanaged dangerous goods can increase the risks to passengers, crew, aircraft, property, and environment. The hazards posed by these materials are often varied and difficult to specifically identify. Therefore, the risks are best addressed by individual certificate holders within the context of their own systems. This AC is not mandatory, and does not constitute a regulation. This AC describes an acceptable means, but not the only means, of complying with applicable regulations to manage dangerous goods operations.

150/5370-2G AAS-100 Operational Safety on Airports During Construction
