Introduction

Part 6 of the Model Regulations provides regulations for the
registration and monitoring of Approved Maintenance Organisations (AMO)
in \[STATE\]. The proper maintenance of aircraft is fundamental to
aviation safety, and requires meticulous record-keeping. Modern practice
among Contracting States varies. In the United States, persons may be
individually licensed, or may be granted maintenance authority as a
member of an AMO. Similarly, a United States Air Operator Certificate
(AOC) holder may use an AMO, or may employ a maintenance organisation
using licensed personnel. In the European Joint Aviation Authorities
(JAA) and now European Aviation Safety Authority (EASA) practice, the
maintenance organisation of an AOC holder must qualify as an AMO in its
own right. Whether or not \[STATE\] adopts the Federal Aviation
Administration (FAA) or JAA approach with their AOC holders, there will
be a need for oversight and regulation of AMO's. Maintenance
requirements for AOC holders with integral maintenance organisations
with no AMO certificate are addressed in Part 9, Air Operator
Certification and Administration. Please note that Section 6.2.1.5(a)(4)
requires an AMO applicant within \[State\] to disclose any and all AMO
certificates in any Contracting State other than \[STATE\]. Many
regional airline consortia use common maintenance facilities in one
Contracting State. This practice does not relieve \[STATE\] from
approving the AMO that its AOC holders use. Knowledge of the other
Contracting State's AMO licensing and regulating practices will allow
the Authority both to communicate with the Authority overseeing the AMO
certificate, and to weigh the AMO requirements of the other Contracting
State for satisfaction of \[STATE\]'s own regulations.

FAA Form 8310-3

#### [[]{#__RefHeading___Toc165360249 .anchor}IS: 6.2.1.12](#quality-system) Quality System  {#is-6.2.1.12-quality-system .unnumbered}

##### In order to show compliance with 9.2.2.3, an AMO should establish its quality system in accordance with the instruction and information contained in the following paragraphs.

1.0. General.

1.1 Terminology.

##### The terms used in the context of the requirement for an AMO's quality system have the following meaning:

###### Accountable Manager. The person acceptable to the Authority who has corporate authority for ensuring that all maintenance activities can be financed and carried out to the standard required by the Authority, and any additional requirements defined by the AMO.

###### Quality assurance. Quality assurance, as distinguished from quality control, involves activities in the business, systems, and technical audit areas. A set of predetermined, systemic actions which are required to provide adequate confidence that a product or service satisfies quality requirements.

1.2 Quality Policy.

**1.2.1** An AMO shall establish a formal, written quality policy
statement that is a commitment by the accountable manager as to what the
quality system is intended to achieve. The quality policy should reflect
the achievement and continued compliance with the \[Model Regulations\]
together with any additional standards specified by the AMO.

**1.2.2** The accountable manager is an essential part of the AMO
management organisation. The term "accountable manager" is intended to
mean the Chief Executive/President/Managing Director/ General Manager,
etc. of the AMO, who by virtue of his or her position has overall
responsibility (including financial) for managing the organisation.

**1.2.3** The accountable manager will have overall responsibility for
the AMO quality system, including the frequency, format and structure of
the internal management evaluation activities as prescribed in paragraph
3.9 below.

**1.3** Purpose of the Quality System.

**1.3.1** The quality system should enable the AMO to monitor compliance
with these \[Model Regulations\], the AMO's manual system, and any other
standards specified by the AMO, or the Authority, to ensure safe
operations and airworthy aircraft.

**1.4 Quality Manager.**

**1.4.1** The function of the quality manager to monitor compliance
with, and the adequacy of, procedures required to ensure safe
operational practices and airworthy aircraft as required by these
\[Model Regulations\] may be carried out by more than one person by
means of different, but complementary, quality assurance programs.

**1.4.2** The primary role of the quality manager is to verify, by
monitoring activity in the field of, maintenance, that the standards
required by the Authority, and any additional requirements defined by
the AMO, are being carried out under the supervision of the relevant
required management personnel.

**1.4.3** The quality manager should be responsible for ensuring that
the quality assurance programme is properly established, implemented and
maintained.

**1.4.4** The quality manager should:

##### Report to the accountable manager;

##### Not be one of the required management personnel; and

##### Have access to all parts of the AMO's, and as necessary, any sub-contractor's organisation. 

**1.4.5** In the case of small/very small AMO's, the posts of the
Accountable Manager and quality manager may be combined.

2.0 Quality System.

2.1 Introduction.

1.  The AMO's quality system should ensure compliance with and adequacy
    of operational and maintenance activities requirements, standards,
    and procedures.

2.  The AMO should specify the basic structure of the quality system
    applicable to the operation.

3.  The quality system should be structured according to the size and
    complexity of the organisation to be monitored.

##### Audit;

##### Auditors;

##### Auditor's independence

##### Audit scope;

##### Audit scheduling;

##### Monitoring and corrective action;

3.2 Quality Inspection.

3.2.1 The primary purpose of a quality inspection is to observe a
particular event/action/document, etc. in order to verify whether
established procedures and requirements are followed during the
accomplishment of that event and whether the required standard is
achieved.

3.2.2 Typical subject areas for quality inspections are:

###### Facilities size and segregation;

###### Office accommodation

###### Work environment

###### Storage

###### Management changes

###### Staff numbers and man-hour plan

###### Competence process

###### Qualifying certifying staff;

###### Records of certifying staff;

###### Issue of authorizations

###### Adequate equipment;

###### Equipment control and calibration;

###### Approved data held;

###### Modified maintenance data;

###### Data availability;

###### Data up to date;

###### Aircraft release;

###### Release document contents;

###### Release control

###### Details on work documents;

###### Operator's copy of release;

###### Record retention;

###### Reporting unairworthy findings;

###### Clear work orders;

###### Procedures per Maintenance Procedures Manual;

###### Suppliers and subcontractors;

###### Acceptance of parts;

###### Parts control in stores;

###### Use of tools;

###### Cleanliness standards;

###### Control of repairs;

###### Aircraft Maintenance Programme completion;

###### Airworthiness directive control;

###### Control of modifications;

###### Control of working documents;

###### Line defect control;

###### Aircraft Technical Log -- Maintenance Records section completion;

###### Pool and loan parts;

###### Return defective parts to base;

###### Product maintenance exemption control;

###### Procedures deviation control;

###### Special services control (NDI);

###### Contractors working teams;

###### Product audit;

###### Privileges and locations control;

###### Limitation control;

###### Control of changes.

3.2.3 Typical methods for quality inspections for maintenance include:

##### Product sampling - the part inspection of a representative sample of the aircraft fleet;

##### Defect sampling - the monitoring of defect rectification performance;

##### Concession sampling - the monitoring of any concession to not carry out maintenance on time;

3.3 Audit.

1.  An audit is a systematic, and independent comparison of the way in
    which an operation is being conducted against the way in which the
    published operational procedures say it should be conducted.

2.  Audits should include at least the following quality procedures and
    processes:

##### A statement explaining the scope of the audit;

##### Planning and preparation;

##### Gathering and recording evidence; and 

##### Analysis of the evidence.

3.  Techniques that contribute to an effective audit are:

##### Interviews or discussions with personnel;

##### A review of published documents;

##### The examination of an adequate sample of records;

##### The witnessing of the activities that make up the operation; and 

##### The preservation of documents and the recording of observations.

3.4. Auditors.

**3.4.1** An AMO should decide, depending upon the complexity of the
organisation, whether to make use of a dedicated audit team or a single
auditor. In any event, the auditor or audit team should have relevant
maintenance experience.

**3.4.2** The responsibilities of the auditors should be clearly defined
in the relevant documentation.

3.5 Auditor's Independence.

**3.5.1** Auditors should not have any day-to-day involvement in the
area of the maintenance activity that is to be audited. An AMO may, in
addition to using the services of full-time dedicated personnel
belonging to a separate quality department, undertake the monitoring of
specific areas or activities by the use of part-time auditors. An AMO
whose structure and size does not justify the establishment of full-time
auditors, may undertake the audit function by the use of part-time
personnel from within its own organisation or from an external source
under the terms of an agreement acceptable to the Authority. In all
cases the AMO should develop suitable procedures to ensure that persons
directly responsible for the activities to be audited are not selected
as part of the auditing team. Where external auditors are used, it is
essential that any external specialist is familiar with the type of
operation and/or maintenance conducted by the operator.

**3.5.2** The AMO's quality assurance programme should identify the
persons within the company who have the experience, responsibility and
authority to:

##### Perform quality inspections and audits as part of ongoing quality assurance;

##### Identify and record any concerns or findings, and the evidence necessary to substantiate such concerns or findings;

##### Initiate or recommend solutions to concerns or findings through designated reporting channels;

##### Verify the implementation of solutions within specific timescales;

##### Report directly to the quality manager.

3.6 Audit Scope.

**3.6.1** AMO's are required to monitor compliance with the operational
and maintenance procedures they have designed to ensure safe operations,
airworthy aircraft and the serviceability of both operational and safety
equipment. In doing so they should as a minimum, and where appropriate,
monitor:

##### Organisation;

##### Plans and company objectives;

##### AMO certification (AMO/Operations specifications)

##### Supervision;

##### Manuals, logs, and records;

##### Duty time limitations, rest requirements, and scheduling;

##### Maintenance programmes and continued airworthiness;

##### Airworthiness directives management;

##### Maintenance accomplishment;

##### Defect deferral;

##### Dangerous goods;

##### Security;

##### Training.

3.7 Audit Scheduling.

**3.7.1** A quality assurance program should include a defined audit
schedule and a periodic review cycle area by area. The schedule should
be flexible, and allow unscheduled audits when trends are identified.
Follow-up audits should be scheduled when necessary to verify that
corrective action was carried out and that it was effective.

**3.7.2** An AMO should establish a schedule of audits to be completed
during a specified calendar period. All aspects of the operation should
be reviewed within every 12 month period in accordance with the
programme unless an extension to the audit period is accepted as
explained below. An AMO may increase the frequency of audits at its
discretion but should not decrease the frequency without the agreement
of the Authority. Audit frequency should not be decreased beyond a 24
month period interval.

**3.7.3** When an AMO defines the audit schedule, significant changes to
the management, organisation, operation, or technologies should be
considered as well as changes to the regulatory requirements.

3.8 Monitoring and Corrective Action.

**3.8.1** The aim of monitoring within the quality system is primarily
to investigate and judge its effectiveness and thereby to ensure that
defined policy and maintenance standards are continuously complied with.
Monitoring activity is based upon quality inspections, audits,
corrective action and follow-up. The AMO should establish and publish a
quality procedure to monitor regulatory compliance on a continuing
basis. This monitoring activity should be aimed at eliminating the
causes of unsatisfactory performance.

**3.8.2.** Any non-compliance identified as a result of monitoring
should be communicated to the manager responsible for taking corrective
action or, if appropriate, the accountable manager. Such non-compliance
should be recorded, for the purpose of further investigation, in order
to determine the cause and to enable the recommendation of appropriate
corrective action.

**3.8.3** The quality assurance programme should include procedures to
ensure that corrective actions are taken in response to findings. These
quality procedures should monitor such actions to verify their
effectiveness and that they have been completed. Organisational
responsibility and accountability for the implementation of corrective
action resides with the department cited in the report identifying the
finding. The accountable manager will have the ultimate responsibility
for resourcing the corrective active action and ensuring, through the
quality manager, that the corrective action has re-established
compliance with the standard required by the Authority, and any
additional requirements defined by the operator.

**3.8.4** Corrective action. Subsequent to the quality inspection/audit,
the AMO should establish:

##### The seriousness of any findings and any need for immediate corrective action;

##### The origin of the finding;

##### What corrective actions are required to ensure that the non-compliance does not recur;

##### A schedule for corrective action;

##### The identification of individuals or departments responsible for implementing corrective action;

##### Allocation of resources by the accountable manager, where appropriate.

3.8.5 The quality manager should:

##### Verify that corrective action is taken by the manager responsible in response to any finding of non-compliance;

##### Verify the corrective action includes the elements outlined in paragraph 3.8.4 above;

##### Monitor the implementation and completion of corrective action'

##### Provide management with an independent assessment of corrective action; implementation and completion;

##### Evaluate the effectiveness of corrective action through follow-up process.

3.9 Management Evaluation.

**3.9.1** A management evaluation is a comprehensive, systematic,
documented review by the management of the quality system, policies and
procedures, and should consider:

##### The results of quality inspections, audits and any other indicators;

##### The overall effectiveness of the management organisation in achieving stated objectives.

**3.9.2** A management should identify and correct trends, and prevent,
where possible, future non-conformities. Conclusions and recommendations
made as a result of an evaluation should be submitted in writing to the
responsible manager for action. The responsible manager should be an
individual who has the authority to resolve issues and take action.

**3.9.3** The accountable manager should decide upon the frequency,
format and structure of internal management evaluation activities.

3.10 Recording.

**3.10.1** Accurate, complete and readily accessible records documenting
the results of the quality assurance programme should be maintained by
the AMO. Records are essential data to enable an operator to analyse and
determine the root causes of non-conformity, so that areas of
non-compliance can be identified and addressed.

**3.10.2** The following records should be retained for a period of 5
years:

##### Audit schedules;

##### Quality inspection and audit reports;

##### Responses to findings;

##### Corrective action reports;

##### Follow-up and closure reports; and

##### Management evaluation reports.

4.0 Quality Assurance Responsibility for Sub-Contractors.

4.1 Sub-Contractors.

**4.1.1** AMO's may decide to sub-contract out certain activities to
external agencies for the provision of services related to areas such
as:

##### Maintenance;

##### Training;

##### Manual preparation.

**4.1.2** The ultimate responsibility for the product or service
provided by the sub-contractor always remains with the AMO. A written
agreement should exist between the AMO and the sub-contractor clearly
defining the safety related services and quality to be provided. The
sub-contractor's safety related activities relevant to the agreement
should be included in the AMO's quality assurance programme.

**4.1.3** The AMO should ensure that the sub-contractor has the
necessary authorisation/approval when required and commands the
resources and competence to undertake the task.

5.0. Quality System Training.

5.1 General.

**5.1.1** An AMO should establish effective, well planned and resourced
quality related briefing for all personnel.

**5.1.2** Those responsible for managing the quality system should
receive training covering:

##### An introduction to the concept of the quality system;

##### Quality management;

##### The concept of quality assurance;

##### Quality manuals;

##### Audit techniques;

##### Reporting and recording; and

##### The way in which the quality system will function in the company.

**5.1.3** Time should be provided to train every individual involved in
quality management and for briefing the remainder of the employees. The
allocation of time and resources should be governed by the size and
complexity of the AMO.

5.2 Sources of Training.

5.2.1 Quality management courses are available from the various
\[National\] or International Standards Institutions, and an AMO should
consider whether to offer such courses to those likely to be involved in
the management of quality systems. AMO's with sufficient appropriately
qualified staff should consider whether to carry out in-house training.

6.0 Organisations with 20 or Less Full-Time Employees.

6.1 Introduction.

6.1.1 The requirement to establish and document a quality system, and to
employ a quality manager applies to all AMO's. References to large and
small operators elsewhere in these \[Model Regulations\] are governed by
aircraft capacity (i.e. more or less than 20 seats) and by mass (i.e.
greater or less than 10 tonnes maximum take-off mass). Such terminology
is not relevant when considering the scale of an operation and the
quality system required. In the context of quality systems therefore,
operators should be categorised according to the number of full time
staff employees.

6.2 Scale of Operation.

6.2.1 AMO's who employ 5 or less full time staff are considered to be
"very small" while those employing between 6 and 20 full time employees
are regarded as "small" operators as far as quality systems are
concerned. Full-time in this context means employed for not less than 35
hours per week excluding vacation periods.

6.2.2 Complex quality systems could be inappropriate for small or very
small operators and the clerical effort required to draw up manuals and
quality procedures for a complex system may stretch their resources. It
is therefore accepted that such operators should tailor their quality
systems to suit the size and complexity of their operation and allocate
resources accordingly.

6.3 Quality System for Small/Very Small AMO's.

6.3.1 For small and very small AMO's it may be appropriate to develop a
quality assurance programme that employs a checklist. The checklist
should have a supporting schedule that requires completion of all
checklist items within a specified timescale, together with a statement
acknowledging completion of a periodic review by top management. An
occasional independent overview of the checklist content and achievement
of the quality assurance should be undertaken.

6.3.2 The "small" AMO may decide to use internal or external auditors or
a combination of the two. In these circumstances it would be acceptable
for external specialists and or qualified organisations to perform the
quality audits on behalf of the quality manager.

6.3.3 If the independent quality audit function is being conducted by
external auditors, the audit schedule should be shown in the relevant
documentation.

6.3.4 Whatever arrangements are made, the operator retains the ultimate
responsibility for the quality system and especially the completion and
follow-up of corrective actions.

##### Except as provided in paragraph (c), tools, equipment, or test equipment other than that recommended by the manufacturer will be acceptable based on at least the following:

###### The AMO shall have a procedure in the Maintenance Procedures Manual if it intends to use equivalent tools, equipment, or test equipment other than that recommended by the manufacturer.

###### The AMO shall have a program to include:

####### A description of the procedures used to establish the competence of personnel that make the determination of equivalency to tools, equipment, or test equipment.

####### Conducting and documenting the comparison made between the specification of the tool, equipment or test equipment recommended by the manufacturer and the equivalent tool, equipment, or test equipment proposed.

####### Ensuring that the limitations, parameters, and reliability of the proposed tool, equipment, or test equipment are equivalent to the manufacturer\'s recommended tools, equipment, or test equipment.

####### Ensuring that the equivalent tool, equipment, or test equipment is capable of performing the appropriate maintenance function, all normal tests, or calibrations, and checking all parameters of the aircraft or aeronautical product undergoing maintenance or calibration.

###### The AMO shall have full control of the equivalent tool, equipment, or test equipment (i.e. ownership, lease, etc.)

##### An AMO approved for base maintenance shall have sufficient aircraft access equipment and inspection platforms/docking such that the aircraft may be properly inspected.

##### The AMO shall have a procedure to inspect/service and, where appropriate, calibrate tools, equipment, and test equipment on a regular basis and indicate to users that an item is within any inspection or service or calibration time limit.

##### The AMO shall have a procedure if it uses a standard (primary, secondary or transfer standards) for performing calibration, to ensure that standard cannot be used to perform maintenance.

##### A clear system of labelling all tooling, equipment and test equipment shall be used to give information on when the next inspection or service or calibration is due, and give status information if the item is unserviceable for any other reason where it may not be obvious. 

##### A clear system of labelling all tooling, equipment, and test equipment shall be used to give information on when such tooling, equipment, and test equipment is not used for product acceptance and/or for making a finding of airworthiness. 

##### A register shall be maintained for all calibrated tools, equipment and test equipment together with a record of calibrations and standards used. 

##### Inspection, service, or calibration on a regular basis shall be in accordance with the equipment manufacturers\' instructions except where the AMO can show by results that a different time period is appropriate in a particular case and is acceptable to the Authority. 

#### [[]{#__RefHeading___Toc165360252 .anchor}IS: 6.4.1.1](#personnel-requirements) Personnel Requirements {#is-6.4.1.1-personnel-requirements .unnumbered}

AMO CAA AAT (1/99) 1

FAA Order 8130.21B; FAA Form 8130-3

EASA 145, Appendix 1; EASA Form 1

TCCA Form 24-0078

##### **LINE-BY-LINE INSTRUCTIONS FOR COMPLETION OF MODEL AMO CAA FORM AAT:** {#line-by-line-instructions-for-completion-of-model-amo-caa-form-aat .unnumbered}

##### Block 1. \[STATE\] (Pre-printed).

##### Block 2. Model CAA, Airworthiness Approval Tag, and Civil Aviation Administration (Pre-printed).

##### Block 3. System Tracking Reference Number.

###### Fill in the unique number established by the CAA-approved numbering system.

###### If the form is computer-generated, it may be produced as programmed by the computer.

NOTE: Shippers must establish a numbering system for traceability in
order to fill out block 3 of the form. This system must also provide a
means of cross-referencing the number(s) and product(s) being shipped.

##### Block 4. Organisation.

###### Fill in the full name and address of the AMO or individual shipping the product(s)/part(s) as applicable:

####### Company name and address.

####### Production Approval Holder (PAH) approval or certificate numbers as issued by the Authority of the State of Manufacturer, when applicable (e.g., production certificate number, approved maintenance organisation certificate numbers, air operator certificate number.

Note: Production certificates are issued to manufacturing companies by
an Authority. The MCARs presume that \[STATE\] will not be a State of
Manufacturer or Design. However, aircraft registered in State will
likely be repaired, altered or rebuilt using parts and components
exported from the State of Manufacturer. Companies performing the
repair, alteration, rebuild and export will be certificated by the State
of Manufacturer as a production approval holder. The PAH is required by
the State of Manufacturer to use the airworthiness approval tag and
certify their work in blocks 14 -- 18 as described in this Part.
Consequently State's which will not be filling out block 14-18 will need
to be familiar with all the uses of this form in order to properly
accept parts and components. Production certificates are described in 14
CFR: 21, Subpart G.

###### When a supplier has direct ship authorisation from a PAH, the following information should be entered:

####### PAH name and address.

####### PAH approval or certificate number.

####### C/o Supplier name and address.

NOTE: If an individual product/part is produced as a spare by a
supplier, the supplier must have either direct ship authority or hold a
production approval (TSO authorisation) for all products/parts shipped.
If the supplier holds its own production approval, and the
products/parts were manufactured and are being shipped under that
approval, the information required in paragraph (1) above should be
listed.

##### Block 5. Work Order, Contract, or Invoice Number.

###### Fill in the contract, work order, or invoice number related to the shipment list, or maintenance release, and state the number of pages attached to the form, including dates, if applicable. If the shipment list contains the information required in Blocks 6 through 12, the respective blocks may be left blank if an original, or true copy, of the list is attached to the form. In this case, the following statement should be entered in Block 13: \"This is the certification statement for the products/parts listed on the attached document dated \_\_\_\_\_\_\_\_\_, containing pages \_\_\_\_\_\_ through \_\_\_\_\_\_.\"

###### In addition, the shipment list must cross-reference the number located in Block 3. The shipment list may contain more than one item; but it is the responsibility of the shipper to determine if the CAA of the importing jurisdiction will accept bulk shipments under a single Model CAA Form \[AAT\]. If the CAA does not permit bulk shipments under a single form, Blocks 6 through 12 of each form must be filled in for each product shipped.

##### Block 6. Item. When Model CAA Form \[AAT\] is issued a single item number or multiple item numbers may be used for the same part number. Multiple items should be numbered in sequence. If a separate listing is used, enter \"List Attached.\" 

NOTE: The blank form can be computer-generated. However, the format
cannot be changed, nor can any words be added or deleted. Pre-printing
of some information is permissible, i.e.; the information in blocks 1,
2, 3, 4, and 19. The size of blocks may be varied slightly, but the form
must remain readily recognisable. The form may also be reduced in
overall size to facilitate placement of the wording on the back of the
form onto the face of the document.

##### Block 7. Description. Enter the name or description of the product/part as shown on the design data. For products/parts that do not have design data available, the name as referenced in a part catalog, overhaul manual, etc., can be used.

##### Block 8. Part Number. Enter each part number of the product.

##### Block 9. Eligibility. State the aircraft, aircraft engine, or propeller make and model on which the parts manufacture approval is eligible for installation. If a part is eligible for installation on more than one model enter the words \"to be verified by installer or TBV by installer.\" Where parts are TSO articles, state \"TSO Article N/A\" since eligibility for installation for TSO articles is determined at the time of installation.

NOTE: For TSO articles CAA Model Form \[AAT\] does not constitute
authority to install a product on a particular aircraft, aircraft
engine, or propeller. The user or installer is responsible for
confirming that the product is eligible for installation by reference to
overhaul manuals, service bulletins, etc., as applicable. While the
information in Block 9 is optional, it should be filled out whenever
possible.

##### Block 10. Quantity. State the quantity of each product/part shipped.

##### Block 11. Serial/Batch Number. State the serial number or equivalent (identified on the part) on the form for each product/part shipped. If a serial number or equivalent is not required on the part, enter \"N/A.\"

##### Block 12. Status/work. Enter \"Newly Overhauled\" for those products that have not been operated or placed in service since overhaul. Enter \"PROTOTYPE\" for products/parts submitted to support type certification programs. Other permissible/appropriate terms to describe the status of the product/part include: \"INSPECTED\", \"REPAIRED,\" \"REBUILT,\" or \"ALTERED.\"

##### Block 13. Remarks. Enter any information or references to support documentation necessary for the user or installer to make a final determination of airworthiness of the products/parts listed in Block 7. Each statement must specify which item identified in Block 6 is related. Examples of information to be supplied are as follows:

###### Any restrictions (e.g., prototype only).

###### Alternative approved part number.

###### Compliance or non-compliance with airworthiness directives or service bulletins.

###### Information on life-limited parts.

###### Manufacturing, cure, or shelf-life data.

###### Drawing and revision level.

###### When used for conformity the word \"CONFORMITY\" must be entered in capital letters. In addition, an explanation of the products/parts use, e.g., pending approved data, type certificate pending, for test only, etc., should be provided. Information concerning a conformity inspection such as design data, revision level, date, project number. 

###### When used for spare parts identify whether the parts are from the original manufacturer or another approved source and are made to the TSO. In addition, if the Airworthiness Approval Tag \[AAT\] is for spare parts or sub components of a CAA approved replacement part, the TSO authorisation should be listed in Block 13.

###### When used for return to service this block should contain the data required by 5.7.1.2. 

##### Blocks 14, 15, 16, 17 and 18: Must not be used for maintenance tasks by Part 6 approved maintenance organisations. These blocks are specifically reserved for release/certification of newly manufactured items in accordance with certification procedures of products and parts of the State of Design or State of Manufacture (e.g. 14 CFR Part 21).

##### Block 19. Return to Service. The information is already pre-printed in the block.

##### Block 20. Signature. Signature of the individual authorised by the air agency, air carrier, or the manufacturer in accordance with 5.6.1.5 (a)(2), (3), and (4). The approval signature shall be manually applied at the time and place of issuance.

##### Block 21. Certificate number. Enter the AMO or air operator operating certificate number. For manufacturers returning to service after rebuilding products/parts the production approval number should be entered.

##### Block 22. Name. The typed or printed name of the individual identified in Block 20.

##### Block 23. Date. The date the Model CAA Form \[AAT\] is signed and the product is returned to service. This does not need to be the same as the shipping date, which may occur at a later date. 

#### [[]{#__RefHeading___Toc165360258 .anchor}IS: 6.5.1.9](#airworthiness-data) Airworthiness Data {#is-6.5.1.9-airworthiness-data .unnumbered}

##### The AMO shall be in receipt of all airworthiness data appropriate to support the work performed from the Authority, the aircraft/aeronautical product design organisation, and any other approved design organisation in the State of Manufacture or State of Design, as appropriate. Some examples of maintenance-related documents are:

###### Civil Aviation Regulations. 

###### Associated advisory material.

###### Airworthiness directives.

###### Manufacturers\' maintenance manuals.

###### Repair manuals.

###### Supplementary structural inspection documents.

###### Service bulletins.

###### Service letters.

###### Service instructions.

###### Modification leaflets.

###### Aircraft maintenance program.

###### NDT Manual, etc.

Note: Paragraph (a) primarily refers to maintenance data that has been
transcribed from the Authority and all Type Certificate holders into the
AMO\'s format, such as customised maintenance cards or computer based
data.

Note: To obtain acceptance from the Authority, it is important that
accuracy of transcription is assured.

##### A procedure shall be established to monitor the amendment status of all data and maintain a check that all amendments are being received by being a subscriber to any document amendment scheme.

##### Airworthiness data shall be made available in the work area in close proximity to the aircraft or aeronautical product being maintained and for supervisors, mechanics, and certifying staff to study.

##### Where computer systems are used to maintain airworthiness data, the number of computer terminals shall be sufficient in relation to the size of the work program to enable easy access, unless the computer system can produce paper copies. Where microfilm or microfiche readers/printers are used, a similar requirement is applicable.
