Part-66 and AMC/GM rev. May 2012 Dear Reader

Dear Reader,You are finding before you the third printed Technical Publication of the Agency, the Part-66 consolidated rules. The format and layout is similar to the previous Technical Publications, Part-M and Part-145. The handbook starts with the newest amendment of Regulation (EC) No. 2042/2003, and is followed by Annex III of this regulation, Part-66. The related Acceptable Means of Compliance and Guidance Material have been included behind the respective Implementing Rules paragraphs also for this version. Again, a CD with the bookmarked and cross-referenced PDF of the handbook, as well as with the applicable Word forms, has been attached.

The next Technical Publications include updated versions of Part-M and Part-145. A probable new publication will be situated in the area of Flight Standards. It will most likely be in an electronic format. In this way, the Technical Publications service also seeks to respond to the varying needs of the different stakeholders.

art A

AMC 66.A.20(b)2 Privileges

The 6 months maintenance experience in 2 years should be understood as consisting of two ele-ments: duration and nature of the experience. The minimum to meet the requirements for these elements may vary depending on the size and complexity of the aircraft and type of operation and maintenance.

1. Duration:

Within an approved maintenance organization:

- 6 months working with the same organisation; or

- 6 months split up into different blocks, working within the same or in different organisations.

The 6 months period can be replaced by 100 days of maintenance experience in accordance with the privileges, whether they have been performed within an approved organisation, or as independent certifying staff according to M.A.801(b)2, or as a combination thereof.

When licence holder maintains and releases aircraft in accordance with M.A.801(b)2, in certain circumstances this number of days may even be reduced by 50% when agreed in advance by the competent authority. These circumstances consider the cases where the licence holder hap-pens to be the owner of an aircraft and carries out maintenance on his own aircraft, or where a licence holder maintains an aircraft operated for low utilization, that does not allow the licence holder to accumulate the required experience. This reduction should not be combined with the 20% reduction permitted when carrying out technical support, or maintenance planning, con-tinuing airworthiness management or engineering activities. To avoid a too long period without experience, the working days should be spread over the intended 6-months period.

2. Nature of the experience:

Depending on the category of the aircraft maintenance licence, the following activities are con-sidered relevant for maintenance experience:

- Servicing;

- Inspection;

- Operational and functional testing;

- Troubleshooting;

- Repairing;

- Modifying;

- Changing component;

- Supervising these activities;

- Releasing aircraft to service.

For category A licence holders, the experience should include exercising the privileges, by means of performing tasks related to the authorization on at least one aircraft type for each licence subcategory. This means tasks as mentioned in AMC 145.A.30(g), including servicing, compo-nent changes and simple defect rectifications.

For category B1, B2 and B3, for every aircraft type rating included in the authorization the expe-rience should be on that particular aircraft or on a similar aircraft within the same licence (sub)category. Two aircraft can be considered as similar when they have similar technology, construc-tion and comparable systems, which means equally equipped with the following (as applicable to the licence category):

(a) For the purpose of this Annex (Part-66), the competent authority shall be:

1. the authority designated by the Member State to whom a person first applies for the issu-ance of an aircraft maintenance licence, or

2. the authority designated by another Member State, in case it would be different, subject to agreement with the authority referred to in point 1. In that case, the licence referred to in point 1 shall be revoked, all the records mentioned in point 66.B.20 shall be transferred and a new licence shall be issued on the basis of these records.

(b) The Agency shall be responsible for defining:

1. the list of aircraft types; and

2. what airframe/engine combinations are included in each particular aircraft type rating.

AMC 66.1(a)

A competent authority may be a ministry, a national aviation authority, or any aviation body desig-nated by the Member State and located within that Member State. A Member State may designate more than one competent authority to cover different areas of responsibility, as long as the designa-tion decision contains a list of the competencies of each authority and there is only one competent authority responsible for each given area of responsibility.

The purpose of 66.1(a)2 is to allow the possibility for a person who already holds a Part-66 licence issued by one Member State (i.e. Member State X) to replace it by a Part-66 licence issued by anoth-er Member State (i.e. Member State Y). This may be useful, for example, in cases where a person holding a licence from Member State X is developing his/her career in a maintenance organisa-tion located in Member State Y. In this case, this person may need to endorse new type ratings based on courses directly approved by the competent authority of Member State Y or may need to endorse new licence (sub)categories based on basic examinations performed by the competent authority of Member State Y.

1. The following definitions apply:

Electrical system means the aircraft electrical power supply source, plus the distribution system to the different components contained in the aircraft and relevant connectors. Lighting systems are also included in this definition. When working on cables and connectors which are part of these electrical systems, the following typical practices are included in the privileges:

Continuity, insulation and bonding techniques and testing;

Crimping and testing of crimped joints;

Connector pin removal and insertion;

Wiring protection techniques.

Avionics system means an aircraft system that transfers, processes, displays or stores analogue or digital data using data lines, data buses, coaxial cables, wireless or other data transmission medium, and includes the systems components and connectors. Examples of avionics systems include the following:

Autoflight;

Communication, Radar and Navigation;

Instruments (see NOTE below);

In Flight Entertainment Systems;

Integrated Modular Avionics (IMA);

On-Board Maintenance Systems;

Information Systems;

Fly by Wire Systems (related to ATA27 Flight Controls);

Fibre Optic Control Systems.

NOTE: Instruments are formally included within the privileges of the B2 licence holders. However, maintenance on electromechanical and pitot-static components may also be released by a B1 license holder.

Simple test means a test described in approved maintenance data and meeting all the following criteria:

The serviceability of the system can be verified using aircraft controls, switches, Built-in Test Equipment (BITE), Central Maintenance Computer (CMC) or external test equip-ment not involving special training.

The outcome of the test is a unique go no go indication or parameter, which can be a single value or a value within an interval tolerance. No interpretation of the test result or interdependence of different values is allowed.

The test does not involve more than 10 actions as described in the approved mainte-nance data (not including those required to configure the aircraft prior to the test, i.e. jacking, flaps down, etc, or to return the aircraft to its initial configuration). Pushing a control, switch or button, and reading the corresponding outcome may be considered as a single step even if the maintenance data shows them separated.

Troubleshooting means the procedures and actions necessary, using approved maintenance data, in order to identify the root cause of a defect or malfunction. It may include the use of BITE or external test equipment.

Line maintenance means any maintenance that is carried out before flight to ensure that the aircraft is fit for the intended flight. It may include:

trouble shooting;

defect rectification;

component replacement with use of external test equipment, if required. Component replacement may include components such as engines and propellers;

scheduled maintenance and/or checks including visual inspections that will detect obvious unsatisfactory conditions/discrepancies but do not require extensive in depth inspection. It may also include internal structure, systems and powerplant items which are visible through quick opening access panels/doors;

minor repairs and modifications which do not require extensive disassembly and can be accomplished by simple means;

for temporary or occasional cases (Airworthiness Directives, hereinafter AD; service bulletins, hereinafter SB) the quality manager may accept base maintenance tasks to be performed by a line maintenance organisation provided all requirements are fulfilled. The Member State will prescribe the conditions under which these tasks may be performed.

Base Maintenance means any task falling outside the criteria that are given above for Line Maintenance.

NOTE:

Aircraft maintained in accordance with "progressive" type programmes need to be indi-vidually assessed in relation to this paragraph. In principle, the decision to allow some "progressive" checks to be carried out is determined by the assessment that all tasks within the particular check can be carried out safely to the required standards at the designated line maintenance station.

2. The category B3 licence does not include any A subcategory. Nevertheless, this does not pre-vent the B3 licence holder from releasing maintenance tasks typical of the A1.2 subcategory for piston-engine non-pressurized aeroplanes of 2000 Kg MTOM and below, within the limitations contained in the B3 licence.

3. The category C licence permits certification of scheduled base maintenance by the issue of a single certificate of release to service for the complete aircraft after the completion of all such maintenance. The basis for this certification is that the maintenance has been carried out by competent mechanics and category B1, B2 and B3 support staff, as appropriate, have signed for the maintenance tasks under their respective specialisation. The principal function of the cat-egory C certifying staff is to ensure that all required maintenance has been called up and signed off by the category B1, B2 and B3 support staff, as appropriate, before issue of the certificate of release to service. Only category C personnel who also hold category B1, B2 or B3 qualifications may perform both roles in base maintenance.

AMC 66.A.20(b)2 Privileges

The 6 months maintenance experience in 2 years should be understood as consisting of two ele-ments: duration and nature of the experience. The minimum to meet the requirements for these elements may vary depending on the size and complexity of the aircraft and type of operation and maintenance.

1. Duration:

Within an approved maintenance organization:

- 6 months working with the same organisation; or

- 6 months split up into different blocks, working within the same or in different organisations.

The 6 months period can be replaced by 100 days of maintenance experience in accordance with the privileges, whether they have been performed within an approved organisation, or as independent certifying staff according to M.A.801(b)2, or as a combination thereof.

When licence holder maintains and releases aircraft in accordance with M.A.801(b)2, in certain circumstances this number of days may even be reduced by 50% when agreed in advance by the competent authority. These circumstances consider the cases where the licence holder hap-pens to be the owner of an aircraft and carries out maintenance on his own aircraft, or where a licence holder maintains an aircraft operated for low utilization, that does not allow the licence holder to accumulate the required experience. This reduction should not be combined with the 20% reduction permitted when carrying out technical support, or maintenance planning, con-tinuing airworthiness management or engineering activities. To avoid a too long period without experience, the working days should be spread over the intended 6-months period.

2. Nature of the experience:

Depending on the category of the aircraft maintenance licence, the following activities are con-sidered relevant for maintenance experience:

- Servicing;

- Inspection;

- Operational and functional testing;

- Troubleshooting;

- Repairing;

- Modifying;

- Changing component;

- Supervising these activities;

- Releasing aircraft to service.

For category A licence holders, the experience should include exercising the privileges, by means of performing tasks related to the authorization on at least one aircraft type for each licence subcategory. This means tasks as mentioned in AMC 145.A.30(g), including servicing, compo-nent changes and simple defect rectifications.

For category B1, B2 and B3, for every aircraft type rating included in the authorization the expe-rience should be on that particular aircraft or on a similar aircraft within the same licence (sub)category. Two aircraft can be considered as similar when they have similar technology, construc-tion and comparable systems, which means equally equipped with the following (as applicable to the licence category):
