What is an ATA Chapter?
ATA Chapters refer to the standardized system of categorizing technical information in the aviation industry, particularly for aircraft maintenance and repair documentation.
"ATA" stands for Air Transport Association, now known as Airlines for America (A4A), which initially developed this system. The ATA Chapters system divides aircraft components and systems into numbered chapters and subchapters, making it easier to reference and organize technical information across different types of aircraft. Each chapter number represents a specific system or a part of the aircraft, such as "Chapter 22: Auto Flight" for autopilot systems or "Chapter 33: Lights" for aircraft lighting systems. This standardized coding system is widely adopted in the industry, helping maintenance personnel, engineers, and technicians to quickly locate and cross-reference information, ensuring consistency and efficiency in aircraft maintenance and operation. Jet Parts Engineering can provide ATA Chapter designation to all of our parts and repairs if needed. Our ecommerce also includes this information along with other data for quick reference.
