ATA Chapters

ATA chapters are a numbering which is a common referencing standard for commercial aircraft documentation published by ATA (Air transportation Association). ATA chapters makes it easy to categorize technical information and uniformity in presenting for All manufacturers of aircraft and its components.

ATA 100 contains the reference to the ATA numbering system which is a common referencing standard for commercial aircraft documentation. The standard numbering system was published by the Air Transport Association on June 1, 1956.

Though the ATA 100 is outdated and replaced with ATA iSpec 2200, it was been used until 2015.

In 1999 the Regularly support Division of Federal Aviation Authority (FAA) finalized a Joint Aircraft System/component code/ATA 100, which was a modified version of Air Transport Association of America (ATA), Specification 100 code. These are four digit codes.

The ATA Technical Information and Communications Committee (TICC) developed a new consolidated specification for the commercial aviation industry, ATA iSpec 2200
In 2000.

The main objective of creating such codes is to make uniformity in technical documentation for All Aircraft. So documents such as Aircraft Maintenance manual (AMM), Structure Repair manual ( SRM), Master Minimum Equipment List (MMEL) and Minimum Equipment List ( MML) will be use the same coding system for all Aircraft despite it’s manufacturer or the manufacturing country.

Currently, there are more than 100 ATA chapters are there many of these chapters are still reserved and some of them are allocated for Air operator use.

how do you remember ATA chapters

well its just straight forward when it comes to memorizing ATA chapters. But there is trick to memorize ATA Chapter Numbers From 21-40 and 51 to 57. because these section follow English Alphabetical order.
