The ATA numbering system, also known as the Air Transport Association (ATA) chapters, is a widely recognized and standardized system used in the aviation industry to document parts, components, and entire commercial aircraft. This system, like many others in the aerospace industry, serves to provide a common understanding for pilots, maintenance technicians, engineers, and others involved in aircraft operations.

The ATA 100 system is divided into several sections, with one of them being the ATA Group. Each group contains specific ATA chapters such as ATA Group – Structure, one of which refers specifically to the components listed under ATA Chapter 50. It’s provide important information on aircraft systems such as electrical power, fire protection, fuel, navigation, hydraulic, and more. If you’re in search of ATA Structure or other ATA names, Aviation Parts Circuit is your one-stop-shop. We specializes in supplying ATA chapters parts of ATA 50 under ATA Group Structure.
