(1)Identification: Information for warehouse staff
-Illustrated Parts Catalog (IPC)
-Illustrated Tool Catalog (ICO or Chapter 13 of the IPC)
(2)Special: Time-sensitive information
-Service Bulletin (SB)
-Alert Service Bulletin (ASB)
3.Definition of required maintenance levels for application of the repairs
The various maintenance tasks are classified in levels so as to take into account the complexity of the tasks, the place of execution of the operations, the equipment and the training of the personnel.
For structural repair requirements, these levels are defined by the letters "O", "I", "I+"
and "D":
-“O” LEVEL (Operation Level): This refers to implementation of simple structural repairs, carried out during line maintenance by the crew and/or line mechanics
using limited equipment, in order to maintain the operational capability of the
aircraft.
-“I” LEVEL (Intermediate level): This refers to implementation of small repairs on or out of the aircraft, in a repair workshop using fixed facilities, by skilled,
trained and qualified personnel, in order to restore the operational capability of
the aircraft or equipment.
For the "O" and "I" levels, repairs may be carried out in accordance
with the instructions of Airbus Helicopters publications: AMM /
SRM / MTC.
The rules defined for the "O" level are applicable to the "I" level.
-“I+” LEVEL: This refers to implementation of repairs on the primary structure or on stressed composite parts, with the approval of the Airbus Helicopters
Technical Support Department,
. In a Repair Center mandatorily approved by Airbus Helicopters,
. Or with mandatory Technical Assistance from Airbus Helicopters if the work is
carried out of an Airbus Helicopters Approved Repair Center,
. Or with the assistance of an Airbus Helicopters Approved Repair Center if the work is performed out of an Airbus Helicopters Approved Repair Center.
“I+” level repairs require approval from the Airbus Helicopters
Technical Support Department. The repair work must be approved
by Airbus Helicopters ("I+" specific maintenance documentation, or
specific repair sheet submitted to Airbus Helicopters for approval),
or transmitted to Airbus Helicopters if already approved by the
supervisory authorities of the repair workshop. The "I+" level work
cards are identified in the work card title.
The rules defined for the "I" level are applicable to the "I+" level.
-"D" LEVEL: This corresponds to repairs which affect the interchangeability of major structural couplings or the general geometry of the aircraft, using tooling
which ensures interchangeability, by a maintenance center and specialists duly
qualified by Airbus Helicopters.
The supply of documentation (SRMD), tooling and "D" level spare
parts is reserved for "D" level Maintenance Centers qualified by
Airbus Helicopters.
An aircraft cannot be reconstituted using the identification plate
of an aircraft which has been declared scrapped by Airbus
Helicopters without the prior written approval of Airbus Helicopters.
The rules defined for the "I+" level are applicable to the "D" level.
Airbus Helicopters reminds you that it is forbidden to reuse structural parts or
assemblies which have been involved in an accident without prior approval from the Airbus Helicopters Technical Support Department.
The major structural couplings are the following:
Landing gear attachment points, MGB bar attachments, attachment points on
transmission deck, engine mount attachment points, fuselage/tail boom junction,
horizontal stabilizer-Fenestron junction and TGB attachment points.
4.Following up the technical publications
A.The manuals are valid only if they are regularly kept up to date by the users.
The Updating department is governed by the “General Terms and Conditions of
Sale” appended to any contract.
Documentation may be distributed in three formats: Paper/DVD/PDF (e-techpub).
B.Advice to operators
Paper manuals that have not been kept up to date must not be used for
helicopter maintenance. They must be destroyed on the spot or clearly marked
“documentation not up to date”.
DVDs must be replaced when each new revision is issued. A DVD that pre-dates
the latest revision must not be used for helicopter maintenance.
The e-techpub documentation is updated directly on the Internet.
5.Updating the manual
A.Normal Revision (NR)
Paper issue:
-The Maintenance Manuals are updated by a regular updating system. The revision completely or partially updates the manual. The revisions are issued

6.Temporary Revision (TR)
A.General
Between two Normal Revisions, Airbus Helicopters may need to make
modifications to points of the manual considered important; this will be done
through temporary revisions. The Temporary Revision deals with information
which requires quick distribution and which cannot wait until the next normal
revision is issued.
Several Temporary Revisions may be issued between two Normal Revisions.
The new, revised or deleted Documentary Units (DU) are issued on yellow color
paper. The changes are indicated by a vertical line in the margin.
Temporary Revisions are identified by the number of the next Normal Revision
followed by a letter (taken in alphabetical order) and a date code.
position and updating
The Temporary Revision is composed of an "Update instructions" section, a List
of Effective Pages of the Temporary Revision, one (or several) List(s) of Effective
Pages for the chapter(s) and one (or several) Documentary Unit(s).
The "Update instructions" section gives a list of the highlights of the Temporary
Revision. This information is issued with each new Temporary Revision (TR).
The List of Effective Pages of the Temporary Revision (LOEDU-TR) identifies
the chapters modified by all the Temporary Revisions. The date code associated
with the Documentary Unit corresponds to the date of the Temporary Revision at which it was modified. This list is issued with each new Temporary Revision and supersedes the previous one. It must be inserted at the beginning of the manual in the preliminary Documentary Units and kept until the next Normal Revision (RN).
The List of Effective Pages of the chapters "XX-LOEDU-TR" identifies the new, revised or deleted Documentary Units of the chapters affected by the Temporary Revisions. The date code associated with the chapter corresponds to the date of the TR at which it was modified. Only the List of Effective Pages of the modified chapters are issued. These lists must be inserted at the beginning of the chapters concerned and they cancel and supersede the previous ones. They must be retained until the next RN.
New, revised or deleted Documentary Units:
-For a new Documentary Unit: the new yellow-colored Documentary Unit must be inserted directly in the manual.
-For a revised Documentary Unit: all the pages of the yellow-colored revised Documentary Unit cancel and supersede all the pages of the white-colored Documentary Unit concerned. This white-colored Documentary Unit must be removed from the manual.
-For a deleted Documentary Unit: only the first page of the Documentary Unit that must be removed is issued on yellow-colored paper through the
Temporary Revision. This page bears the word "DELETED". It cancels and supersedes all the pages of the white-colored Documentary Unit concerned.
This white-colored Documentary Unit must be removed from the manual.
ALL TEMPORARY REVISIONS INCORPORATED INTO
THE MANUAL MUST BE RECORDED IN THE RECORD OF
TEMPORARY REVISIONS.
PDF issue:
The Temporary Revision is composed of "Highlights", a List of Effective Pages of the Temporary Revision, one (or several) List(s) of Effective Pages and one (or several) Documentary Unit(s).
The "Highlights" list the major points of the Temporary Revision. This information is issued with each new Temporary Revision.
The List of Effective Pages of the Temporary Revision (LOEDU-TR) identifies
the chapters modified by all the Temporary Revisions. The date code associated with the Documentary Unit corresponds to the date of the Temporary Revision at which it was modified. This list is issued with each new Temporary Revision and
supersedes the previous one. It must be inserted at the beginning of the manual
in the preliminary Documentary Units and kept until the next NR.
The List of Effective Pages of the chapters "LOEDU-TR" identifies the new,
revised or deleted Documentary Units of the chapters affected by the Temporary
Revisions. The date code associated with the chapter corresponds to the date of
the TR at which it was modified. Only the List of Effective Pages of the modified
chapters are issued.
DVD issue:
The Temporary Revision is composed of "Highlights" and one (or several)
Documentary Unit(s).
The "Highlights" list the major points of the Temporary Revision. This information
is issued with each new Temporary Revision.
The "Highlights" of the Temporary Revision identifies the DUs modified by all of
the Temporary Revisions. The date code associated with the Documentary Unit
corresponds to the date of the Temporary Revision at which it was modified. This
list is issued with each new Temporary Revision and supersedes the previous
one. The manual revision date code is indicated in the "LOIM".
ALL TEMPORARY REVISIONS INCORPORATED IN THE
MANUAL MUST BE RECORDED IN THE RECORD OF
TEMPORARY REVISIONS.
7.Erratum
This procedure is used to correct composition errors that do not in any way affect the technical data involving flight safety and the certification of the aircraft. This procedure is used to correct these errors rapidly and is completely separated from the revisions.
The date code marked on the replacement page is underlined but it remains
unchanged.
Consequently, the page enclosed with the erratum page must replace the page
issued previously.
8.Preprint
Preprint is a preliminary edition, which is used to transmit an update of the technical documentation in advance of the normal process of management and publication of the information.
This procedure is used:
-to reply to a customer after he has reported irregularities that require changes to the technical publications,
-to introduce new parts and/or systems not included as part of technical publications supplied by Airbus Helicopters.
Airbus Helicopters approves the contents of the data transmitted by Preprint.
For the approved parts (certification), no page can be sent before
approval is granted by the authorities.
Rules for the Preprint diffusion process:
-The Documentary Units are printed on salmon-colored paper.
-The Documentary Units bear the word "PREPRINT" in the diagonal.
-The Documentary Units are identified by a new date code.
-The Documentary Units must be inserted in place of the modified Documentary Units.
Airbus Helicopters preferably transmits the Preprints electronically.
In any case no preliminary edition will remain as is. It will always be followed by
the standard procedure of revision (TR and RN). The DUs must be removed by the customer upon receipt of the corresponding DU TR and/or DU RN which take into account the modifications transmitted through Preprint.
position of the manual
The Aircraft Maintenance Manual (AMM) is made up of two parts:
-Part I of the manual contains all the descriptive type data for all the systems. This Part I is called Systems Description Section (SDS). It is physically separated from Part II and is totally self-contained.
-Part II contains the data required for the maintenance and fault isolation operations and procedures.
10.Structure of the manual
The AMM is broken down into several levels in accordance with the ATA Specification No.100, Revision 31, with a "Chapter - Section - Subject" numbering system that uses six digits.
11.Structure pages
The AMM contains a series of pages called "Structure pages". They contain general instructions and/or guidelines to find the information.
The structure pages contained in the AMM are as follows:
-Update instructions.
-Title page.
-Record of temporary revisions.
-List of effective pages of the manual.
-Introduction.
-List of Service Bulletins.
-List of chapters.
12.Chapter structure pages
Each chapter starts with a List of Effective Pages of the Documentary Units (LOEDU).
This list gives the aircraft version or aircraft serial number effectivity of each
Documentary Unit.
13.Breakdown into chapters
The manual is broken down into chapters, in accordance with the ATA 100
Specification.
The chapter below was added:
Chapter 01:
-List of Materials (in AMM Part II).
-List of Critical Parts (depending on aircraft).
The numbering principle for the Manual is a breakdown into Chapter - Section -
Subject, in a digital form:
-the first three digits are given by the ATA 100 Specification
Example: 62-2x-yz
62-2 Main Rotor (system)
-the last three digits are left at the manufacturer's disposal:
. digit x to complete a sub-system number,
. digits yz to complete a sub-sub-system number.
Example: 62-2x-yz
62-21 Main Rotor Hub (sub-system)
62-21-11 Spring vibration damper (sub-sub-system)
14.Chapter breakdown into topics (SDS section)
Inside the chapters of the manual, the subjects are broken down into topics which gather tasks depending on the maintenance operations.
The System Description Section gives explanations on the location, use, description and operation of the complete system and its sub-systems.
This section is designed so that it can be used as a training manual.
The identification comes in the form of a series of Documentary Units (DU).
There are two title levels:
-The higher level represents a set of information of the same type (e.g.: General, General Description, Detailed Description, etc.). All the illustrations of a
"Documentary Unit" are grouped at the end of this Documentary Unit.
Each UD is broken down into subsets.
These subsets represent a group of paragraphs.
Each subset begins with a title (Introduction, Description, Characteristics,
Operation, etc.).
15.Chapter breakdown into topics (AMM section)
A.Fault Isolation
This section gives the information for the ground maintenance teams to locate
failures and faulty operation and to determine the necessary corrective actions.
This topic comes in the form of a table:
-The first column "Failure Indication" gives a detailed description of the fault.
-The second column "Probable Cause" lists the possible causes of the fault, in the logical fault isolation order.
-The third column "Corrective action" indicates the action(s) to be taken to correct each possible cause of the failures listed.
B.Maintenance tasks
These topics describe the processes which allow the ground maintenance
personnel to carry out the maintenance, removal/installation, adjustment, check
operations, etc.
When the task is given for reference, the Chapter - Section - Subject number is followed by the task number:
Example: 62-21-00, 4-1 Removal - Main rotor hub
If an instruction requires the execution of a task, its reference number appears between brackets at the end of the instruction.
Example: Remove main rotor hub (62-21-00, 4-1).
Depending on aircraft configuration, the reference number of the task may be preceded by a configuration number. The selection of this configuration number is the responsibility of the operator.
ex: conf 001 62-21-00, 4-1,
ex: conf 002 62-21-00, 4-1
Further to changes in aircraft configuration, compliance with a Service Bulletin, change of component part number ("Manufacturer Part Number") or a series production modification, the maintenance task can be followed by a configuration letter. The selection of the configuration letter is the responsibility of the operator. Example: 62-21-00, 4-1a Removal - Main rotor hub (PRE MOD 07xxxx) Example: 62-21-00, 4-1b Removal - Main rotor hub (POST MOD 07xxxx)
Each task contains the information below:
-List of Applicable Documents
1. Main information
Contains references to other tasks that are essential to carry out the
procedure.
2. Conditional information
Contains references to other tasks the application of which in the procedure depends on the maintenance environment, the choice or skills of the
customer.
3. General information
Contains references to other tasks containing information that is supposedly known by the operator, as well as the code of the manual(s) where such
information can be found.
-List of special tools
This is the list of the special tools required to carry out the Task. These "special" tools are those that are not normally available to the maintenance personnel. These tools are identified with their "part numbers" and descriptions.
These special tools are listed in the ICO (or in Chapter 13 of the IPC).
Certain tools (not listed in the ICO (or in Chapter 13 of the IPC) and not normally available to the maintenance teams) are identified by the term "Commercial" to indicate that they are purchased "off the shelf".
-List of Materials
This is the list of the consumable materials required to carry out the Task. They are identified with a "CM" code and their description.
Details of the products that correspond to these codes are given in W.C.
20-01-01-102 of manual MTC.
The 20-01-01-102 of MTC describes the "NATO" code, the different references of the French, German and US Specifications and the list of the source products. It also refers to the implementation procedures described in the Standard Practices Manual (MTC) for certain products.
Certain materials are identified by the term "Commercial". This means that they can be purchased off the shelf.
-List of Routine Replacement Parts
This is the list of the parts discarded and replaced during a Task.
This list comes in the form of a table:
-the first and second columns give the position of the part (text/figure/set),
-the third column gives the name of the part,
-the fourth column gives the part number (MP/N).
-Job Set-up (optional)
This topic specifies how to prepare the helicopter for the work to be done.
-Procedure
The procedure is described in the form of a logical sequence of phases, broken down as follows:
(1) phase
(a) sub-phase of (1)
1 sub-phase of (a)
a sub-phase of 1
The figures and tables are numbered in chronological order so that they can be used for several phases inside the same Task.
All the figures inside a Task are gathered at the end of the Task.
The items are identified in a continuous ascending order starting with Item 1 on Set 1 and finishing with Item n on Set m. If a part appears on several figures/sets, it shall always have the same item number.
Figure 401 is the first figure in a "Removal / Installation" topic.
Table 602 is the second table in an "Inspection / Check" topic.
A figure can include several sets. In this case, the figure number remains the same, and only the set number is changed.
Furthermore, the items are defined on all the sets of the figure.
Figure 401 (Sheet 1)
Figure 401 (Sheet 2)
If there are no specific indications of the tightening torques on
the figures, then the tightening torque values are the Standard
torque values. To determine this standard value, refer to (MTC
20-02-05-404).

18.Glossary
ATTACHMENT
The visual check is carried out on the attachment points of a component (condition of the safetying, marks on self-locking nuts). It may be necessary to complete this examination with a tactile check (manual application of a load on the component to detect any fault in the assembly).
CHECK
A check consists in comparing the measurement of a magnitude (force, time,
pressure, temperature, length, etc.) with a theoretical value. The resulting action
consists in bringing back this magnitude to a value that ranges within its tolerances, through adjustment or a maintenance action (e.g.: check of tightening torques, check of play, etc.).
CLEANLINESS
The cleanliness check consists in making sure that there is no foreign matter, no fluid seepage or splashes and no "fouled" areas likely to conceal a fault.
CONDITION
The visual examination concerns the general external condition of a component and the points that could modify its initial condition (deformation, breaks, cracks, scores, corrosion, signs of overheating or wear).。
