JASC/ATA Code Lookup

Easily search and copy component codes from the JASC (ATA) code table developed by the FAA.

The ATA chapters each have a code that refers to the numbering system and referencing standards for commercial aircraft maintenance documentation. The chapter numbers are standardized across all commercial aircraft and each aircraft manual details different systems and procedures of the particular aircraft. ATA chapter in each manual provide information on parts, benefitting repair technicians, airliners, suppliers, and various others on what parts are, what they do, how to repair them, and beyond.

The ATA codes/chapters were created by the Air Transport Association in 1956, which represented the airliners of North America. ATA codes / chapters were released to provide guidelines for technical manuals and maintenance. Since then, the Air Transport Association, now operating as Airlines for America, does not update the codes/chapters directly. Now called the Joint Aircraft System/Component Code (JASC), the Federal Aviation Administration (FAA) last published an update on October 27, 2008. Currently, the JASC / ATA Codes have been combined with the ATA Spec 2100.
