Complete List of ATA Chapters (ATA 100) – Aircraft Systems & Maintenance Guide
Complete List of ATA Chapters (ATA 100 Specification) – Aircraft Systems Explained
The ATA 100 chapter numbering system, developed by the Air Transport Association (ATA), is a globally accepted standard used in aircraft maintenance manuals, training programs, and aviation documentation. It provides a structured method to classify aircraft systems, structures, and components, making troubleshooting, maintenance, and learning consistent across different aircraft manufacturers.
This guide is written for aircraft maintenance engineers (AMEs), aviation students, and aviation enthusiasts who want a clear and complete understanding of ATA chapters.

Why ATA Chapters Matter in Aviation
ATA chapters are essential for aircraft maintenance licensing exams, technical manuals (AMM, IPC, FCOM), and daily line and base maintenance. Understanding this system allows engineers and technicians to quickly locate faults, perform repairs, and communicate efficiently across global aviation operations.
