Aircraft ATA Chapter List, ATA 100 Codes - Air Transportation Association

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.

Frequently Asked Questions (FAQ) for ATA Chapter

What Are ATA Chapters and Why Are They Used?
ATA chapters, or Air Transport Association chapters, are a standardized referencing standard used in aviation to categorize and organize information related to aircraft maintenance and documentation. ATA chapters are used to provide a clear and consistent way of referencing parts, components, and systems of commercial aircraft, promoting an ease of MRO operations and part procurement.
How Are ATA Chapters Organized and Numbered?
ATA chapters are organized into distinct groups based on general function or use, common examples including “Aircraft General,” “Aircraft Systems,” “Structure,” and more. Within each of these groups, sets of chapters are organized together, each having a two digit code for representation. For example, ATA chapter 25 represents "Equipment/Furnishings," and it falls within the wider "Aircraft Systems" section. By following such information, customers, maintenance staff, and other personnel can save time and effort when carrying out various processes.
How Many Chapters Are in the ATA Numbering System?
ATA chapters generally range from ATA 00 to ATA 99 for the original ATA 100 system, though further chapters do exist in outdated documentation. While no longer updated, the ATA 100 system remains the most prevalent in use.
