Aircraft ATA Chapters List

The Air Transport Association (ATA) 100 refers to the ATA numbering system, a commonly used standardized system that serves for documenting 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 other aerospace personnel. The number system was first implemented in 1956 and is widely in 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. Take the time to explore our various ATA chapter part lists as provided on this page to quickly find everything you need.

The ATA 100 chapters consists of chapters ranging from 0-99 which are then 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 ATA chapters 00-18 and refers to generic documents regarding airworthiness, hardware, and so on. The second section, Aircraft Systems, ranges from ATA chapters 20-49 and includes information on the many different systems of a commercial aircraft, including those such as power, communications, hydraulics, and more. ATA 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.
