ATA Specification 100

[crazy_cancuk]

Hey Guys,

 

Anyone know a good web site where I could find a listing of the ATA codes?

 

Thank you...

Somewhere here in the puzzle palace we have a complete listing on a Word document and I will post it when found

Here is one I am working on

ATA 100

Numbering System

 

 

Chapterization

The subject matter is divided into chapters and groups of chapters to facilitate the location of information. This chapterization provides a functional breakdown of the entire airplane.

Information on all units that comprise a system will be found in the chapter identified by the name of that system or by a general name indicative of the several systems which may be covered in that chapter.

Thus, all units relating to the generation and distribution of electrical power are covered in Chapter 24, ELECTRICAL POWER, while electrically driven pumps and valves serving the fuel system are covered in Chapter 28, FUEL. Also, all units of the elevator control system, hydraulic, mechanical and electrical units, are included in Chapter 27, FLIGHT CONTROLS. 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 major functional system to which the subject pertains. The middle part of the number is the SECTION number and serves to identify all of the coverage pertaining to a system, subsystem, or group of related assemblies,including all units that are functionally a part of the system or group of related assemblies. The last part of the number is the SUBJECT number and serves to identify all information relative to a specific unit, minor assembly, simple system or simple circuit.

For example:

In accordance with the ATA Specification 100, complete system information is included in

subjects identified by the third part of the subject number being a dash-zero (-0) number. The

descriptions of units which comprise the system or subsystem are also included with the complete system information to the extent necessary for understanding how they work in performing their function in the system. In those cases where the units are sufficiently complex, additional description and operation type information is given at the unit level.

In the case of complex, multisystem chapters such as Flight Controls, the basic chapter section number (27-00) description and operation will consist of only a very general description of each of the various major sections covered in the chapter.

In the case of complex, multisubject chapters such as Equipment and Furnishings, Chapter 25, which serve to collect information on various systems which are separate but which are related in ultimate function, the basic chapter section number (25-00) is omitted entirely or is used only to tabulate and cross reference the systems included. Chapter 25 - EQUIPMENT AND

FURNISHINGS, and Chapter 34 - NAVIGATION fall into this category.

In the case of a complex section or system which consists of several systems or subsystems, a general description of the overall section, system and/or subsystems, is covered at the major section level and identified by the section number ending in zero (0) as well as the subject number ending in dash-zero (-0). For instance subject number 23-40-0 contains general description and operation information on the overall interphone systems, while the subject numbers 23-41-0, 23-42-0, etc. cover minor section level detail description, operation and maintenance information for the interphone subsystems.

 

Page Identification 

The four elements of page identification, which are located along the lower border, are:

· Chapter-Section-Subject Number

· Page Number

· Page Date

· Page Code Number

The subjects are divided into reasonably small topics and subtopics to enable the user to locate the desired information more readily. The topics as defined by ATA Specification 100 are:

DESCRIPTION AND OPERATION

TROUBLE SHOOTING and MAINTENANCE PRACTICES

 The subtopics as defined by ATA Specification 100 are

· SERVICING

· REMOVAL/INSTALLATION

· ADJUSTMENT/TEST

· INSPECTION/CHECK

· CLEANING/PAINTING

· APPROVED REPAIRS.

The page blocks for these topics and subtopics are as follows:

Topic or Subtopic Page Block

· DESCRIPTION AND OPERATION (D&O) 1 to 100

· TROUBLE SHOOTING (TS) 101 to 200

· MAINTENANCE PRACTICES (MP) 201 to 300

· SERVICING (SRV) 301 to 400

· REMOVAL/INSTALLATION (R/I) 401 to 500

· ADJUSTMENT/TEST (A/T) 501 to 600

· INSPECTION/CHECK (I/C) 601 to 700

· CLEANING/PAINTING (C/P) 701 to 800

· APPROVED REPAIRS (AR) 801 to 900

Normally each subtopic is written as an individual topic, however if all subtopics for one subject are brief, they are combined into one topic entitled MAINTENANCE PRACTICES and released in the 201 to 300 page block.

Whenever general maintenance instructions do not fall within one of the designated subtopics, the maintenance instructions will be released in the 201 to 300 page block. If the 201 to 300 page block consists of only one such subtopic, the 201 to 300 page block topic will be titled after the type of maintenance instructions. If the 201 to 300 page block consists of more than one such subtopic, the 201 to 300 page block will be titled MAINTENANCE PRACTICES.

ATA Spec 100 is contained in a publication that is produced by the Air Transport Association. You won''t find free copies on the internet anywhere very easily because of copyright issues.

 

ATA vigorously guards their publications so I for one wouldn''t want to go on record as providing copies. Anyway, most companies have at least a partial listing of the spec in maintenance manuals as so forth and for day to day maintenance you really don''t need to know it.

 

So..I wouldn''t hold my breath waiting for internet access to ATA Spec 100.

[crazy_cancuk]

That is all very interesting. I did not know that it was copy written and guarded so much. They gave us a really bad copy of general set at school. So that is just my wondering if it was aviable on the net.

 

Thanks guys...

Sorry but I missed one other dumb comment knowing the ATA spec "as so forth and for day to day maintenance you really don''t need to know it."

 

So tell me how are you going to find the chapter on electrical systems in a 7000 page B737-700 manual or CD if you don''t know it is chapter 24????????????????

 

[Guest graunch1]

According to a number of my buddies and from my paltry 40+ years in the biz, -----ATA 100 is public domain. It is used in most airframe manufacturer''s manuals, many of the AME/AMT text books and as I showed above, available on-line.I think the first version I have with a listing is from a L188 manual written in the mid 1950s.

 

Isn''t that what these forums are about???

 

Helping others not being anal about your versions of supposed copyrights?

 

Copyright protection is used to protect the value of information for the originator/developer/writer etc. Using it for monetary gain is usually the biggest offense.

 

If you want the entire ATA 100 Specification you can purchase the 4" manual from ATA but that is similar to the ARINC specifications manuals. Are you now going to say that listing ARINC spec''s such as ARINC 429,629,700 is violating their copyright? Give your head a shake man.

 

If you look at many of the safety magazines they all give open use to their information as will many other books that promote aviation.

Sorry I guess I should not have said anything --- after all you are wearing a TIE.

 

 

The original post was for a listing of the ATA 100 numbers listing not a disertation on the specification books.
