ATA Spec 100: Manufacturers' Technical Data The Air Transport Association released the newest

version of ATA Spec 100 in 1999.

According to the A4A website, this information will

not be revised and has been combined with ATA Spec 2100 to produce the ATA iSpec 2200: Information Standards for Aviation Maintenance manual.

This specification defines a widely used numbering scheme

for aircraft parts and the appearance of printed aircraft maintenance information. The Federal Aviation Administration's JASC (Joint Aircraft

System/Component) code table provides a modified version of ATA Spec 100.

ATA Spec 100 contains format and content guidelines for

technical manuals written by aviation manufacturers and suppliers, and is used by airlines and other segments of the industry in the maintenance of their respective products.

This document provides the industrywide standard for

aircraft systems numbering, often referred to as the ATA system or ATA chapter numbers. The format and content guidelines define the data

prepared as conventional printed documentation. In 2000 ATA Spec 100 and ATA Spec 2100 were

incorporated into ATA iSpec 2200: Information Standards for Aviation Maintenance.

Developed by the Air Transport Association, ATA iSpec

2200 is recognized as the global industry standard in aviation, providing guidelines for the content, structure, and electronic exchange of information related to aircraft engineering, maintenance, and flight operations.

The data specifications are a collected suite of data

specifications related to maintenance requirements and procedures, aircraft configuration control, and flight operations. The iSpec 2200 was developed as a consolidation between

ATA Spec 100 and Spec 2100, and provides guidance for preparation of technical documentation related to aircraft maintenance.

ATA Spec 100 contains format and content guidelines for technical

manuals written by aviation manufacturers and suppliers and is used by airlines and other segments of the industry in the maintenance of their respective products. This document provides the industry-wide standard for aircraft

systems numbering, often referred to as ATA system or chapter numbers. The format and content guidelines define the data prepared as

conventional printed documentation.

Maintenance documents GENERAL The maintenance documents for the aircrafts supply help for

all maintenance activities.

Many different documents work together to permit you to

maintain the airplane.

The maintenance documents will help you do scheduled and

unscheduled maintenance work.

Scheduled Maintenance These are examples of scheduled maintenance work: Through stop checks Airplane turn around Daily checks Planned checks.

You use these documents to do scheduled maintenance: Maintenance Planning Document (MPD) Airplane Maintenance ManuaL (AMM).

These documents supply supporting data to do

scheduled maintenance:

System Schematics Manual (SSM) Wiring Diagram Manual (WDM) Structural Repair Manual (SRM)

Illustrated Parts Catalog (IPC).

Unscheduled maintenance These are examples of unscheduled maintenance

work:

Flight faults Ground faults Service problems

Structural damage.

You

use these documents to do unscheduled maintenance:

Fault Reporting Manual (FRM) Fault Isolation Manual (FIM) Built-In Test Equipment Manual (BITE) Structural Repair Manual (SRM) Dispatch Deviations Guide (DDG) Airplane Maintenance Manual (AMM).

MAINTENANCE MANUALS

Maintenance planning Document The

Maintenance Planning Document (MPD) defines the tasks for each type of scheduled maintenance check.

Airlines use the MPD to make task cards that the

technician uses during the maintenance checks.

Airplane Maintenance Manual The Airplane Maintenance Manual (AMM) has two parts. Part I is the Systems Description Section (SDS). This section replaces the description and operation (D and

O) section of the older airplane models.

Part II is Practices and Procedures. It has data related to these functions: Removal / installation of components. Component Location. Maintenance practices. Servicing. Adjustment/test. Inspection/check. CLeaning/painting. Repair.

System Schematic Manual. The System Schematic Manual (SSM) gives the user an understanding

of system operation and helps in the fault isolation process. It supplies the interconnection of all LRUs of a system or subsystem. It also supplies a general knowledge about system operation. Wiring Diagram Manual. The Wiring Diagram Manual (WDM) supplies details of the point-to-

point wiring on the airplane

The Illustrated Parts Catalog. The Illustrated Parts Catalog supplies part replacement data. This data includes: Replacement part number. Part illustrations. Supplier data. Specification numbers. Recomended spares. Service Bulletin activity.

Standard Wiring Practices Manual. The

Standard Wiring Practices Manual has instructions for maintenance and repair of the wiring of all Boeing airplanes.

It is not customized.

Fault Reporting Manual. The flight crew uses the Fault Reporting Manual

(FRM) to improve communication with maintenance personneL.

The flight crew uses the FRM to get fault codes for

airplane faults.

These faults can be flight deck effects or other faults.

The FRM has standard log book write-ups for each fault

code. The fault code permits faster maintenance when the

airplane lands. FRM fault codes refer you to the FIM.

Fault Isolation Manual. You use the Fault Isolation Manual (FIM) to repair airplane

faults. You start the fault isolation process with FRM fault codes

or a fault description. The FIM wiII identify the maintenance action(s) to correct

the fault.

BITE Manual. You use the BITE manual to get fault data from the

airplane built in test equipment.

If you start the fault isolation process with observed

faults, the BITE manual will identify which observed faults need data from the built in test equipment.

The BITE manual has the BITE procedures from the

FIM.

Structural Repair Manual The Structural Repair Manual (SRM) supplies descriptive

information and specific instructions to help in field repair of airplane structure. The SRM is not customized.

It has data relative to these areas: Allowable damage evaluation. Typical repairs. Material identification. Material substitution. Fastener instalLation. Alignment check.

Planning.

Dispatch Deviation Guide. The

Dispatch Deviation Guide (DDG) supplies Boeings recommended minimum equipment required for dispatch in the Master Mnimum Equipment List (MMEL).

It also supplies the procedures for dispatch with a

fault if permitted.

Training information point. Each maintenance document has an introduction to show

you how to use that document

AMM PART I - INTRODUCTION The Airplane Maintenance Manual (AMM) Part 1 is the

first of the two parts of the AMM.

It is called the Systems Description Section (SDS). Both Part I and Part II of the AMM show the

configuration of the airplanes in an operator's fleet. configuration changes.

They have frequent revisions for improvements and for

Purpose. The SDS gives descriptions of the interfaces, function, and

operation of the airplane systems and subsystems. You use these descriptions to become familiar with the

airplane systems so that you can do fault isolation and system maintenance. The SDS content can be used as a training manual.

Organization. The SDS uses text/graphic paravisuals (page

sets). Each graphic has one or more pages of text that describe the information on the graphic.

The graphic has the primary information and the

associated text page(s) have the support information or explanations. The SDS uses a horizontal (sometimes called landscape)

format.

Divisions. The SDS organization is by ATA chapter (system) or

chapter/section (subsystem). Each ATA chapter/section usually defines an airplane

system or subsystem.

Each subject of the SDS has this information: Purpose/introduction. General description. Component location. Interface. Operation.

Functional description. Training information points (TIPs).

AMM PART II - INTRODUCTION

Part II of the AMM contains the maintenances

practices and procedures to do maintenance on the airplane.

Chapter Numbering System. The manual has a tab section for each ATA chapter. Within each tab section, the manual has more divisions

that use the assigned subject number (ASN) list number XX-VV-ZZ, where: XX is the ATA chapter YY is the subsystem or sub-subsystem ZZ is the unit (component).

The table of

contents for each chapter lists the maintenance procedures in numerical order for each subsystem and sub-subsystem.

For each subsystem or sub-subsystem, the maintenance

tasks are in alphabetical order based on the page numbers described below.

Page Numbering System Each page has two numbers in the Lower right

corner: the ASN and a topic page number. Each topics is made up of a page block. Each page block is for a special type of information.

These are the page blocks:Page TypeMAINTENANCE PRACTICES (MP) SERVICING (SRV) REMOVAL / INSTALLATION (R/I) ADJUSTMENT / TEST (A/T) INSPECTION / CHECK (l/C) CLEANING / PAINTING (C/P)

Page Block201-299 301 399 401-499 501-599 601-699 701-799

REPAIRS (AR)DISPATCH DEVIATIONS GUIDE (DDG)

801-899901-999

Dispatch Deviation Guide.

If all the topics for an ATA chapter, subsystem, or sub-

subsystem are brief, all the topics are in a single MAINTENANCE PRACTICES page block. The dispatch deviations guide page block has procedures with maintenance tasks that prepare the airplane for flight with certain systems / components inoperative. It also has tasks that put the airplane back to its usual condition.

Training Information Point. Each chapter of part II of the AMM has a List of effective

pages at the beginning of each chapter .

Training Information Point. Chapter 12 of the AMM has the title SERVICING. This chapter has procedures to fill and drain items

such as: Fuel. Oil. Hydraulic fluid. Water. Tire pressure.
