Complete List of Aircraft ATA 100 Chapters

The Air Transport Association (ATA) 100 refers to the ATA numbering system, a commonly used standardized system used to document parts, components, or entire commercial aircraft. Like most standardization systems within the aerospace industry, the ATA 100 is used to provide a clear, common understanding for pilots, maintenance technicians, engineers, and more. The number system was implemented in 1956 and is in wide use throughout the industry to this day, despite no longer being officially recognized. What made this system so popular was its application to all aircraft. For example, the reference number for a Boeing Aircraft is the same number used for an Airbus.

The ATA 100 is 100 chapters ranging from 0-99 broken up into seven sections. These sections are aircraft general, aircraft systems, structure, propeller/rotor, power plant, miscellaneous, and peculiar military chapters. Aircraft general ranges from 00-18 and refers to generic documents regarding airworthiness, hardware, and so on. The second section, aircraft systems, ranges from chapters 20 to 49 with information about the many different systems on a commercial aircraft, like power, communications, hydraulics, and more. Chapters 50-57 pertain to the aircraft structural components such as the fuselage, wings, nacelle, and doors. 60-84 contain information regarding the propeller/rotor and power plant, and the final chapters refer to miscellaneous components relating to flight and information regarding military-specific parts and components.
