ATA Chapter

ATA Chapter

ATA Chapter numbers are a common referencing standard for all commercial aircraft and their documentation.

The standard numbering system was published by the Air Transport Association on June 1, 1956; it has since been updated to keep pace with aircraft development.

The unique aspect of the chapter numbers is its relevance for all manuals and aircraft. Thus a chapter reference number for a Boeing 747 will be the same for an Airbus A320 and the same for each manual, such as the AMM, IPC and SRM.
