ATA 100 contains the reference to the ATA numbering system which is a common referencing standard for commercial aircraft documentation. This commonality permits greater ease of learning and understanding for pilots, aircraft maintenance technicians, and engineers alike. The standard numbering system was published by the Air Transport Association on June 1, 1956. While the ATA 100 numbering system has been superseded, it continued to be widely used until it went out of date in 2015, especially in documentation for general aviation aircraft, on aircraft Fault Messages (for Post Flight Troubleshooting and Repair) and the electronic and printed manuals.
The Joint Aircraft System/Component (JASC) Code Tables was a modified version of the Air Transport Association of America (ATA), Specification 100 code. It was developed by the FAA's, Regulatory Support Division (AFS-600). This code table was constructed by using the new JASC code four digit format, along with an abbreviated code title. The abbreviated titles have been modified in some cases to clarify the intended use of the accompanying code. The final version of the JASC/ATA 100 code was released by the FAA in 2008.
In 2000 the ATA Technical Information and Communications Committee (TICC) developed a new consolidated specification for the commercial aviation industry, ATA iSpec 2200. It includes an industry-wide approach for aircraft system numbering, as well as formatting and data content standards for documentation output. The main objectives of the new specification are to minimize cost and effort expended by operators and manufacturers, improve information quality and timeliness, and facilitate manufacturers' delivery of data that meet airline operational needs. More recently, the international aviation community developed the S1000D standard, an XML specification for preparing, managing, and using equipment maintenance and operations information.
The unique aspect of the chapter numbers is its relevance for all aircraft. Thus a chapter reference number for a Boeing 747 will be the same for other Boeing aircraft, a BAe 125 and Airbus Aircraft. Examples of this include Oxygen (Chapter 35), Electrical Power (Chapter 24) and Doors (Chapter 52). Civil aviation authorities will also organize their information by ATA chapter like the Master Minimum Equipment List (MMEL) Guidebook from Transport Canada.
The ATA chapter format is always CC-SS, where CC is the chapter and SS the section, see ATA extended list section below for details. Some websites, like aircraft parts resellers, will sometimes refer to ATA 72R or 72T for reciprocating and turbine engines (jet or turboprop), this nomenclature is not part per se of the ATA numbering definition. The ATA 72 subchapter are different for reciprocating engines and turbine engines. Under JASC/ATA 100 the reciprocating engine are now under ATA 85.
