I was training the new guy, and this is what I told him: ATA chapters (sometimes called "ATA 100 System Codes") are a way of categorizing the various systems that are on a plane, originally created by the Air Transport Association in 1956. Look at any Component Maintenance Manual (CMM) for any civilian aircraft. At the bottom of every single page is the ATA chapter for that manual.

AT A Codes: This is the standard numbering system commonly used for aircraft documentations, which was developed by Air Transport Association (ATA) in June 1956 . It is generally covered ATA100 chapter numbers. Which is very useful to understands the areas of aircrafts/ engines / system etc and few people will know this: The full ATA chapter codes are made up by each manufacturer (not by any government or neutral authority). The OEM's must follow the traditional designations of the first two numbers, but assigning the last four is something that they figure out for themselves. So within one manufacturer, similar the ATA chapters generally imply similar parts. Of course - that makes sense. BUT....and here is where it gets interesting: A different manufacturer can make a completely different part and assign it exactly the same ATA numbers. Here's an example. These are all hydraulics (chapter 29), they all have the same ATA system code, but they are for completely different, unrelated parts:32 Landing Gear (MLG retraction cylinders, actuators, uplock assemblies, MLG door actuators, bogie harnesses, metering valves, safety valves, drag brace actuators, door release actuators, bypass valves, steering actuators, brake manifold assemblies, isolator assemblies, NLG retraction actuators, relief valves, control valves, pressure drop indicators, unlock actuator, proximity sensors) Looking for online definition of ATA or what ATA stands for?

The following list of systems,sub-systems and titles shows examples of the breakdown of a 'TYPICAL' manual according to ATA100. the major divisions are termed 'Groups' ,each group being divided into Chapters and allocated blocks of chapter numbers. Thus:-GROUP CHAPTER NUMBERS Aircraft General 1-19 Aircraft Systems 20-4 I have an Asus A7V socket A motherboard with a VIA Apollo KT133 chipset. This means that I have ATA100 or UltraDMA/100 support for certain Hard Drives . I have two Fujitsu model MPG3409AT Hard drives, one set as master, one as slave, both attached to the PRIMARY Ultra ATA 100 IDE connector
The Group, Chapter and Section breakdown used in the manual is in accordance with ATA Specification No. 100. Subject Numbering. Chapters are broken down into sections and subjects each of which is numbered in a three-part subject-numbering system. The first number in the three-part subject number is the CHAPTER number and serves to identify the. Thus a chapter reference number for a Boeing 747 will be the same for other Boeing aircraft, a BAe 125 and Airbus Aircraft. Examples of this include Oxygen (Chapter 35), Electrical Power (Chapter 24) and Doors (Chapter 52).- Wikipedia. For instance, ATA100 reference code 27-50 implies the chapter Flight Controls, section Flaps 78 Engine Exhaust (thrust reversers, thrust reverser actuators, cabin temperature selector valves, brake lock, synchro shaft lock, locking actuator, center drive units, interlock valves, flexible shaft assemblies, blocker doors, ballscrew gearbox assemblies)
