The ATA 100 contains the reference to the ATA numbering system, which is a common reference standard for commercial aircraft documentation. This commonality allows for greater ease of learning and understanding for pilots, aircraft maintenance technicians, and engineers. The standard numbering system was published by the Air Transport Association on June 1, 1956. Although the ATA 100 numbering system has been superseded, it continued to be widely used until it became out of date in 2015, especially in documentation. for general aviation aircraft, in aircraft failure messages (for troubleshooting and post-flight repairs) and electronics and printed manuals that are necessary for the correct operation of aircraft and thus the security that continues to grow in aviation not only in one country but internationally thanks to the continuous technological advances that are more innovative every day.

The Joint Aircraft System / Component Code Table (JASC) was a modified version of the Air Transport Association of America (ATA) Specification 100 code. It was developed by the FAA's Regulatory Support Division (AFS-600). This code table was constructed by using the new four-digit format of the JASC code, as well as by using a short code title. The abbreviated titles have been modified in some cases to clarify the intended use of the accompanying code. The final version of the JASC / ATA 100 code was published by the FAA in 1999.
