(d) If an aircraft is not within a controlled environment, or managed by an M.A. Subpart G approved continuing
airworthiness management organisation that does not hold the privilege to carry out airworthiness reviews, the
airworthiness review certificate shall be issued by the competent authority following a satisfactory assessment based
on a recommendation made by an appropriately approved continuing airworthiness management organisation sent
together with the application from the owner or operator. This recommendation shall be based on an airworthiness
review carried out in accordance with M.A.710.

(e) Whenever circumstances show the existence of a potential safety threat, the competent authority may decide to carry
out the airworthiness review and issue the airworthiness review certificate itself. In this case, the owner or operator
shall provide the competent authority with:

— the documentation required by the competent authority,

— suitable accommodation at the appropriate location for its personnel, and

— when necessary the support of personnel appropriately qualified in accordance with Part-66.

Appendix IV

Approval Ratings

ORGANISATION APPROVAL CLASS AND RATING SYSTEM

1.

Except as stated otherwise for the smallest organisation in paragraph 11, Table 1 outlines the full extent of approval
possible under M.A. Subpart F in a standardised form. An organisation must be granted an approval ranging from a
single class and rating with limitations to all classes and ratings with limitations.

2.

In addition to Table 1 the M.A. Subpart F approved maintenance organisation is required by Subpart-F to indicate
scope of work in the maintenance organisation exposition. See also paragraph 10.

3. Within the approval class(es) and rating(s) granted by the Member State, the scope of work specified in the mainte-
nance organisation exposition defines the exact limits of approval. It is therefore essential that the approval class(es)
and rating(s) and the organisation's scope of work are compatible.

4. A category A class rating means that the M.A. Subpart F approved maintenance organisation may carry out mainte-
nance on the aircraft and any component (including engines/APUs) only whilst such components are fitted to the
aircraft except that such components can be temporarily removed for maintenance when such removal is expressly
permitted by the aircraft maintenance manual to improve access for maintenance subject to a control procedure in
the maintenance organisation exposition acceptable to the Member State The limitation section will specify the
scope of such maintenance thereby indicating the extent of approval.

5. A category B class rating means that the M.A. Subpart F approved maintenance organisation may carry out mainte-
nance on the uninstalled engine/APU (‘Auxiliary Power Unit’) and engine/APU components only whilst such compo-
nents are fitted to the engine/APU except that such components can be temporarily removed for maintenance when
such removal is expressly permitted by the engine/APU manual to improve access for maintenance. The limitation
section will specify the scope of such maintenance thereby indicating the extent of approval. A M.A. Subpart F
approved maintenance organisation with a category B class rating may also carry out maintenance on an installed
engine during ‘base’ and ‘line’ maintenance subject to a control procedure in the maintenance organisation exposi-
tion. The maintenance organisation exposition scope of work shall reflect such activity where permitted by the
Member State.

6. A category C class rating means that the M.A. Subpart F approved maintenance organisation may carry out mainte-
nance on uninstalled components (excluding engines and APUs) intended for fitment to the aircraft or engine/APU.
The limitation section will specify the scope of such maintenance thereby indicating the extent of approval. A
Subpart-F approved maintenance organisation with a category C class rating may also carry out maintenance on an
installed component during base and line maintenance or at an engine/APU maintenance facility subject to a control
procedure in the maintenance organisation exposition. The maintenance organisation exposition scope of work shall
reflect such activity where permitted by the Member State.

7. A category D class rating is a self contained class rating not necessarily related to a specific aircraft, engine or other
component. The D1 — Non-Destructive Testing (NDT) rating is only necessary for a Subpart-F approved mainte-
nance organisation that carries out NDT as a particular task for another organisation. A M.A. Subpart F approved
maintenance organisation with a class rating in A or B or C category may carry out NDT on products it is main-
taining subject to the maintenance organisation exposition containing NDT procedures, without the need for a D1
class rating.

8. The ‘limitation’ section is intended to give the Member State maximum flexibility to customise the approval to a
particular organisation. Table 1 specifies the types of limitation possible and whilst maintenance is listed last in each
class rating it is acceptable to stress the maintenance task rather than the aircraft or engine type or manufacturer, if
this is more appropriate to the organisation. An example could be avionic systems installations and maintenance.

9. Table 1 makes reference to series, type and group in the limitation section of class A and B. Series means a specific
type series such as Cessna 150 or Cessna 172 or Beech 55 series or continental O-200 series etc. Type means a
specific type or model such as Cessna 172RG type. Any number of series or types may be quoted. Group means for
example Cessna single piston engined aircraft or Lycoming non-supercharged piston engines etc.

L 315/39

10. When a lengthy capability list is used which could be subject to frequent amendment, then such amendment shall
be in accordance with a procedure acceptable to the Member State and included in the maintenance organisation
exposition. The procedure shall address the issues of who is responsible for capability list amendment control and
the actions that need to be taken for amendment. Such actions include ensuring compliance with Subpart-F for
products or services added to the list.

11. A M.A. Subpart F approved maintenance organisation which employs only one person to both plan and carry out

all maintenance can only hold a limited scope of approval rating. The maximum permissible limits are:-

ANNEX II

(Part-145)

145.1 General

For the purpose of this Part, the competent authority shall be:

1. for organisations having their principal place of business in a Member State, the authority designated by that Member

State, or;

2. for organisations having their principal place of business located in a third country, the Agency.

SECTION A

145.A.10 Scope

This Section establishes the requirements to be met by an organisation to qualify for the issue or continuation of an
approval for the maintenance of aircraft and components.

145.A.15 Application

An application for the issue or variation of an approval shall be made to the competent authority in a form and manner
established by such authority.

145.A.20 Terms of approval

The organisation shall specify the scope of work deemed to constitute approval in its exposition (Appendix II to this Part
contains a table of all classes and ratings).

145.A.25 Facility requirements

The organisation shall ensure that:

(a) Facilities are provided appropriate for all planned work, ensuring in particular, protection from the weather
elements. Specialised workshops and bays are segregated as appropriate, to ensure that environmental and work area
contamination is unlikely to occur.

1. For base maintenance of aircraft, aircraft hangars are both available and large enough to accommodate aircraft on

planned base maintenance;

2. For component maintenance, component workshops are large enough to accommodate the components on

planned maintenance.

(b) Office accommodation is provided for the management of the planned work referred to in paragraph (a), and certi-
fying staff so that they can carry out their designated tasks in a manner that contributes to good aircraft maintenance
standards.

(c) The working environment including aircraft hangars, component workshops and office accommodation is appro-
priate for the task carried out and in particular special requirements observed. Unless otherwise dictated by the parti-
cular task environment, the working environment must be such that the effectiveness of personnel is not impaired:

1. temperatures must be maintained such that personnel can carry out required tasks without undue discomfort.

2. dust and any other airborne contamination are kept to a minimum and not be permitted to reach a level in the
work task area where visible aircraft/component surface contamination is evident. Where dust/other airborne
contamination results in visible surface contamination, all susceptible systems are sealed until acceptable condi-
tions are re-established.

3.

lighting is such as to ensure each inspection and maintenance task can be carried out in an effective manner.

4. noise shall not distract personnel from carrying out inspection tasks. Where it is impractical to control the noise
source, such personnel are provided with the necessary personal equipment to stop excessive noise causing
distraction during inspection tasks.

5. where a particular maintenance task requires the application of specific environmental conditions different to the

foregoing, then such conditions are observed. Specific conditions are identified in the maintenance data.

L 315/50

EN

Official Journal of the European Union

28.11.2003

6. the working environment for line maintenance is such that the particular maintenance or inspection task can be
carried out without undue distraction. Therefore where the working environment deteriorates to an unacceptable
level in respect of temperature, moisture, hail, ice, snow, wind, light, dust/other airborne contamination, the parti-
cular maintenance or inspection tasks must be suspended until satisfactory conditions are re-established.

(d) Secure storage facilities are provided for components, equipment, tools and material. Storage conditions ensure
segregation of serviceable components and material from unserviceable aircraft components, material, equipment
and tools. The conditions of storage are in accordance with the manufacturer's instructions to prevent deterioration
and damage of stored items. Access to storage facilities is restricted to authorised personnel.

145.A.30 Personnel requirements

(a) The organisation shall appoint an accountable manager who has corporate authority for ensuring that all mainte-
nance required by the customer can be financed and carried out to the standard required by this Part. The accoun-
table manager shall:

system, including the associated feedback system as required by 145.A.65(c). The appointed person shall have direct
access to the accountable manager to ensure that the accountable manager is kept properly informed on quality and
compliance matters.

(d) The organisation shall have a maintenance man-hour plan showing that the organisation has sufficient staff to plan,
perform, supervise, inspect and quality monitor the organisation in accordance with the approval. In addition the
organisation shall have a procedure to reassess work intended to be carried out when actual staff availability is less
than the planned staffing level for any particular work shift or period.

(e) The organisation shall establish and control the competence of personnel involved in any maintenance, management
and/or quality audits in accordance with a procedure and to a standard agreed by the competent authority. In addi-
tion to the necessary expertise related to the job function, competence must include an understanding of the applica-
tion of human factors and human performance issues appropriate to that person's function in the organisation.
‘Human factors’ means principles which apply to aeronautical design, certification, training, operations and mainte-
nance and which seek safe interface between the human and other system components by proper consideration of
human performance. ‘Human performance’ means human capabilities and limitations which have an impact on the
safety and efficiency of aeronautical operations.

(f) The organisation shall ensure that personnel who carry out and/or control a continued airworthiness non-destructive
test of aircraft structures and/or components are appropriately qualified for the particular non-destructive test in
accordance with the European or equivalent Standard recognised by the Agency. Personnel who carry out any other
specialised task shall be appropriately qualified in accordance with officially recognised Standards. By derogation to
this paragraph those personnel specified in paragraphs (g) and (h)(1) and (h)(2), qualified in Part-66 category B1 may
carry out and/or control colour contrast dye penetrant tests.

(g) Any organisation maintaining aircraft, except where stated otherwise in paragraph (j), shall in the case of aircraft line
maintenance, have appropriate aircraft type rated certifying staff qualified as category B1 and B2 in accordance with
Part-66 and 145.A.35.

In addition such organisations may also use appropriately task trained certifying staff qualified as category A in
accordance with Part-66 and 145.A.35 to carry out minor scheduled line maintenance and simple defect rectifica-
tion. The availability of such category A certifying staff shall not replace the need for Part-66 category B1 and B2
certifying staff to support the category A certifying staff. However, such Part-66 category B1 and B2 staff need not
always be present at the line station during minor scheduled line maintenance or simple defect rectification.

(h) Any organisation maintaining aircraft, except where stated otherwise in paragraph (j) shall:

1.

in the case of base maintenance of large aircraft, have appropriate aircraft type rated certifying staff qualified as
category C in accordance with Part-66 and 145.A.35. In addition the organisation shall have sufficient aircraft
type rated staff qualified as category B1 and B2 in accordance with Part-66 and 145.A.35 to support the category
C certifying staff.

(i) B1 and B2 support staff shall ensure that all relevant tasks or inspections have been carried out to the

required standard before the category C certifying staff issues the certificate of release to service.

(ii) The organisation shall maintain a register of any such B1 and B2 support staff.

(iii) The category C certifying staff shall ensure that compliance with paragraph (i) has been met and that all
work required by the customer has been accomplished during the particular base maintenance check or work
package, and shall also assess the impact of any work not carried out with a view to either requiring its
accomplishment or agreeing with the operator to defer such work to another specified check or time limit.

2.

in the case of base maintenance of aircraft other than large aircraft have either:

(i) appropriate aircraft type rated certifying staff qualified as category B1 and B2 in accordance with Part-66 and

145.A.35 or,

(ii) appropriate aircraft type rated certifying staff qualified in category C assisted by B1 and B2 support staff as

specified in paragraph (1).

(i) Component certifying staff shall comply with Part-66.

(j) By derogation to paragraphs (g) and (h), the organisation may use certifying staff qualified in accordance with the

following provisions:

1. For organisation facilities located outside the Community territory certifying staff may be qualified in accordance
with the national aviation regulations of the State in which the organisation facility is registered subject to the
conditions specified in Appendix IV to this Part.

2. For line maintenance carried out at a line station of an organisation which is located outside the Community
territory, the certifying staff may be qualified in accordance with the national aviation regulations of the State in
which the line station is based, subject to the conditions specified in Appendix IV to this Part.

3. For a repetitive pre-flight airworthiness directive which specifically states that the flight crew may carry out such
airworthiness directive, the organisation may issue a limited certification authorisation to the aircraft commander
and/or the flight engineer on the basis of the flight crew licence held. However, the organisation shall ensure that
sufficient practical training has been carried out to ensure that such aircraft commander or flight engineer can
accomplish the airworthiness directive to the required standard.

authorisation to the commander and/or the flight engineer on the basis of the flight crew licence held subject to
being satisfied that sufficient practical training has been carried out to ensure that the commander or flight engi-
neer can accomplish the specified task to the required standard. The provisions of this paragraph shall be detailed
in an exposition procedure.

5. In the following unforeseen cases, where an aircraft is grounded at a location other than the main base where no
appropriate certifying staff are available, the organisation contracted to provide maintenance support may issue a
one-off certification authorisation:

(i) to one of its employees holding equivalent type authorisations on aircraft of similar technology, construction

and systems; or

L 315/52

EN

Official Journal of the European Union

28.11.2003

(ii) to any person with not less than five years maintenance experience and holding a valid ICAO aircraft mainte-
nance licence rated for the aircraft type requiring certification provided there is no organisation appropriately
approved under this Part at that location and the contracted organisation obtains and holds on file evidence
of the experience and the licence of that person.

All such cases as specified in this subparagraph shall be reported to the competent authority within seven days of the
issuance of such certification authorisation. The organisation issuing the one-off authorisation shall ensure that any such
maintenance that could affect flight safety is re-checked by an appropriately approved organisation.

145.A.35 Certifying staff and category B1 and B2 support staff

(a) In addition to the appropriate requirements of 145.A.30(g) and (h), the organisation shall ensure that certifying staff
and category B1 and B2 support staff have an adequate understanding of the relevant aircraft and/or components to
be maintained together with the associated organisation procedures. In the case of certifying staff, this must be
accomplished before the issue or re-issue of the certification authorisation.

‘Category B1 and B2 support staff’ means those category B1 and B2 staff in the base maintenance environment who
do not hold necessarily certification privileges. ‘Relevant aircraft and/or components’, means those aircraft or compo-
‘Certification authorisation’ means the authorisation
nents specified in the particular certification authorisation.
issued to certifying staff by the organisation and which specifies the fact that they may sign certificates of release to
service within the limitations stated in such authorisation on behalf of the approved organisation.

(b) Excepting those cases listed in 145.A.30(j) the organisation may only issue a certification authorisation to certifying
staff in relation to the basic categories or subcategories and any type rating listed on the aircraft maintenance licence
listed in Part 66, subject to the licence remaining valid throughout the validity period of the authorisation and the
certifying staff remaining in compliance with Part 66.

(c) The organisation shall ensure that all certifying staff and category B1 and B2 support staff are involved in at least six
months of actual relevant aircraft or component maintenance experience in any consecutive two year period. For
the purpose of this paragraph ‘involved in actual relevant aircraft or component maintenance’ means that the person
has worked in an aircraft or component maintenance environment and has either exercised the privileges of the
certification authorisation and/or has actually carried out maintenance on at least some of the aircraft type systems
specified in the particular certification authorisation.

(d) The organisation shall ensure that all certifying staff and category B1 and B2 support staff receive sufficient conti-
nuation training in each two year period to ensure that such staff have up-to-date knowledge of relevant technology,
organisation procedures and human factor issues.

(e) The organisation shall establish a programme for continuation training for certifying staff and category B1 and B2
support staff, including a procedure to ensure compliance with the relevant paragraphs of 145.A.35 as the basis for
issuing certification authorisations under this Part to certifying staff, and a procedure to ensure compliance with Part
66.

(f) Except where any of the unforeseen cases of 145.A.30(j)(5) apply, the organisation shall assess all prospective certi-
fying staff for their competence, qualification and capability to carry out their intended certifying duties in accor-
dance with a procedure as specified in the exposition prior to the issue or re-issue of a certification authorisation
under this Part.

(g) When the conditions of paragraphs (a), (b), (d), (f) and, where applicable, paragraph (c) have been fulfilled by the
certifying staff, the organisation shall issue a certification authorisation that clearly specifies the scope and limits of
such authorisation. Continued validity of the certification authorisation is dependent upon continued compliance
with paragraphs (a), (b), (d), and where applicable, paragraph (c).

(h) The certification authorisation must be in a style that makes its scope clear to the certifying staff and any authorised
person who may require to examine the authorisation. Where codes are used to define scope, the organisation shall
make a code translation readily available. ‘Authorised person’ means the officials of the competent authorities, the
Agency and the Member State who has responsibility for the oversight of the maintained aircraft or component.

(i) The person responsible for the quality system shall also remain responsible on behalf of the organisation for issuing
certification authorisations to certifying staff. Such person may nominate other persons to actually issue or revoke
the certification authorisations in accordance with a procedure as specified in the exposition.

The staff records shall contain:

1. details of any aircraft maintenance licence held under Part-66;

2. all relevant training completed

3. the scope of the certification authorisations issued, where relevant, and

4. particulars of staff with limited or one-off certification authorisations.

The organisation shall retain the record for at least two years after the certifying staff or B1 or B2 support staff have
ceased employment with the organisation or as soon as the authorisation has been withdrawn. In addition, upon request,
the maintenance organisation shall furnish certifying staff with a copy of their record on leaving the organisation.

The certifying staff shall be given access on request to their personal records as detailed above.

(k) The organisation shall provide certifying staff with a copy of their certification authorisation in either a documented

or electronic format.

(l) Certifying staff shall produce their certification authorisation to any authorised person within 24 hours.

(m) The minimum age for certifying staff and category B1 and B2 support staff is 21 years.

145.A.40 Equipment, tools and material

(a) The organisation shall have available and use the necessary equipment, tools and material to perform the approved

scope of work.

1. Where the manufacturer specifies a particular tool or equipment, the organisation shall use that tool or equip-
ment, unless the use of alternative tooling or equipment is agreed by the competent authority via procedures
specified in the exposition.

2. Equipment and tools must be permanently available, except in the case of any tool or equipment that is so infre-
quently used that its permanent availability is not necessary. Such cases shall be detailed in an exposition proce-
dure.

3. An organisation approved for base maintenance shall have sufficient aircraft access equipment and inspection

platforms/docking such that the aircraft can be properly inspected.

(b) The organisation shall ensure that all tools, equipment and particularly test equipment, as appropriate, are controlled
and calibrated according to an officially recognised standard at a frequency to ensure serviceability and accuracy.
Records of such calibrations and traceability to the standard used shall be kept by the organisation.

145.A.42 Acceptance of components

(a) All components shall be classified and appropriately segregated into the following categories:

1. Components which are in a satisfactory condition, released on an EASA Form 1 or equivalent and marked in

accordance with Part-21 Subpart Q.

2. Unserviceable components which shall be maintained in accordance with this section.

3. Unsalvageable components which are classified in accordance with 145.A.42(d).

4. Standard parts used on an aircraft, engine, propeller or other aircraft component when specified in the manufac-

turer's illustrated parts catalogue and/or the maintenance data.

5. Material both raw and consumable used in the course of maintenance when the organisation is satisfied that the
material meets the required specification and has appropriate traceability. All material must be accompanied by
documentation clearly relating to the particular material and containing a conformity to specification statement
plus both the manufacturing and supplier source.

(b) Prior to installation of a component, the organisation shall ensure that the particular component is eligible to be

(d) Components which have reached their certified life limit or contain a non-repairable defect shall be classified as
unsalvageable and shall not be permitted to re-enter the component supply system unless certified life limits have
been extended or a repair solution has been approved according to Part-21.

145.A.45 Maintenance data

(a) The organisation shall hold and use applicable current maintenance data in the performance of maintenance,
including modifications and repairs. ‘Applicable’ means relevant to any aircraft, component or process specified in
the organisation's approval class rating schedule and in any associated capability list.

In the case of maintenance data provided by an operator or customer, the organisation shall hold such data when the
work is in progress, with the exception of the need to comply with 145.A.55(c).

(b) For the purposes of this Part, applicable maintenance data shall be any of the following:

1. Any applicable requirement, procedure, operational directive or information issued by the authority responsible

for the oversight of the aircraft or component;

2. Any applicable airworthiness directive issued by the authority responsible for the oversight of the aircraft or

component;

3. Instructions for continuing airworthiness,

issued by type certificate holders, supplementary type certificate
holders, any other organisation required to publish such data by Part-21 and in the case of aircraft or compo-
nents from third countries the airworthiness data mandated by the authority responsible for the oversight of the
aircraft or component;

4. Any applicable standard, such as but not limited to, maintenance standard practices recognised by the Agency as

a good standard for maintenance;

5. Any applicable data issued in accordance with paragraph (d).

(c) The organisation shall establish procedures to ensure that if found, any inaccurate, incomplete or ambiguous proce-
information or maintenance instruction contained in the maintenance data used by maintenance

dure, practice,
personnel is recorded and notified to the author of the maintenance data.

(d) The organisation may only modify maintenance instructions in accordance with a procedure specified in the mainte-
nance organisation's exposition. With respect to those changes, the organisation shall demonstrate that they result in
equivalent or improved maintenance standards and shall inform the type-certificate holder of such changes. Mainte-
nance instructions for the purposes of this paragraph means instructions on how to carry out the particular mainte-
nance task: they exclude the engineering design of repairs and modifications.

(e) The organisation shall provide a common work card or worksheet system to be used throughout relevant parts of
the organisation. In addition, the organisation shall either transcribe accurately the maintenance data contained in
paragraphs (b) and (d) onto such work cards or worksheets or make precise reference to the particular maintenance
task or tasks contained in such maintenance data. Work cards and worksheets may be computer generated and held
on an electronic database subject to both adequate safeguards against unauthorised alteration and a back-up elec-
tronic database which shall be updated within 24 hours of any entry made to the main electronic database. Complex
maintenance tasks shall be transcribed onto the work cards or worksheets and subdivided into clear stages to ensure
a record of the accomplishment of the complete maintenance task.

Where the organisation provides a maintenance service to an aircraft operator who requires their work card or work-
sheet system to be used then such work card or worksheet system may be used. In this case, the organisation shall estab-
lish a procedure to ensure correct completion of the aircraft operators' work cards or worksheets.

(f) The organisation shall ensure that all applicable maintenance data is readily available for use when required by main-

tenance personnel.

(g) The organisation shall establish a procedure to ensure that maintenance data it controls is kept up to date. In the
case of operator/customer controlled and provided maintenance data, the organisation shall be able to show that
either it has written confirmation from the operator/customer that all such maintenance data is up to date or it has
work orders specifying the amendment status of the maintenance data to be used or it can show that it is on the
operator/customer maintenance data amendment list.

145.A.47 Production planning

(a) The organisation shall have a system appropriate to the amount and complexity of work to plan the availability of
all necessary personnel, tools, equipment, material, maintenance data and facilities in order to ensure the safe
completion of the maintenance work.

(b) The planning of maintenance tasks, and the organising of shifts, shall take into account human performance limita-

tions.

(c) When it is required to hand over the continuation or completion of maintenance tasks for reasons of a shift or
personnel changeover, relevant information shall be adequately communicated between outgoing and incoming
personnel.

145.A.50 Certification of maintenance

(a) A certificate of release to service shall be issued by appropriately authorised certifying staff on behalf of the organisa-
tion when it has been verified that all maintenance ordered has been properly carried out by the organisation in
accordance with the procedures specified in 145.A.70, taking into account the availability and use of the mainte-
nance data specified in 145.A.45 and that there are no non-compliances which are known that hazard seriously the
flight safety.

(b) A certificate of release to service shall be issued before flight at the completion of any maintenance.

(c) New defects or incomplete maintenance work orders identified during the above maintenance shall be brought to
the attention of the aircraft operator for the specific purpose of obtaining agreement to rectify such defects or
completing the missing elements of the maintenance work order. In the case where the aircraft operator declines to
have such maintenance carried out under this paragraph, paragraph (e) is applicable.

(d) A certificate of release to service shall be issued at the completion of any maintenance on a component whilst off
the aircraft. The authorised release certificate or airworthiness approval tag identified as EASA Form 1 in Appendix I
to this Part constitutes the component certificate of release to service. When an organisation maintains a component
for its own use, an EASA Form 1 may not be necessary depending upon the organisation's internal release proce-
dures defined in the exposition.

(e) By derogation to paragraph (a), when the organisation is unable to complete all maintenance ordered, it may issue a
certificate of release to service within the approved aircraft limitations. The organisation shall enter such fact in the
aircraft certificate of release to service before the issue of such certificate.

(f) By derogation to paragraph (a) and 145.A.42, when an aircraft is grounded at a location other than the main line
station or main maintenance base due to the non-availability of a component with the appropriate release certificate,
it is permissible to temporarily fit a component without the appropriate release certificate for a maximum of 30
flight hours or until the aircraft first returns to the main line station or main maintenance base, whichever is the
sooner, subject to the aircraft operator agreement and said component having a suitable release certificate but other-
wise in compliance with all applicable maintenance and operational requirements. Such components shall be
removed by the above prescribed time limit unless an appropriate release certificate has been obtained in the mean-
time under paragraph (a) and 145.A.42.

145.A.55 Maintenance records

(a) The organisation shall record all details of maintenance work carried out. As a minimum, the organisation shall
retain records necessary to prove that all requirements have been met for issuance of the certificate of release to
service, including subcontractor's release documents.

(b) The organisation shall provide a copy of each certificate of release to service to the aircraft operator, together with a

copy of any specific approved repair/modification data used for repairs/modifications carried out.

(c) The organisation shall retain a copy of all detailed maintenance records and any associated maintenance data for two

years from the date the aircraft or component to which the work relates was released from the organisation.

1. Records under this paragraph shall be stored in a safe way with regard to fire, flood and theft.

tapes etc., in an environment that ensures they remain in good condition.

3. Where an organisation approved under this Part terminates its operation, all retained maintenance records
covering the last two years shall be distributed to the last owner or customer of the respective aircraft or compo-
nent or shall be stored as specified by the competent authority.

145.A.60 Occurrence reporting

(a) The organisation shall report to the competent authority, the state of registry and the organisation responsible for
the design of the aircraft or component any condition of the aircraft or component identified by the organisation
that has resulted or may result in an unsafe condition that hazards seriously the flight safety.

(b) The organisation shall establish an internal occurrence reporting system as detailed in the exposition to enable the
collection and evaluation of such reports,
including the assessment and extraction of those occurrences to be
reported under paragraph (a). This procedure shall identify adverse trends, corrective actions taken or to be taken by
the organisation to address deficiencies and include evaluation of all known relevant information relating to such
occurrences and a method to circulate the information as necessary.

(c) The organisation shall make such reports in a form and manner established by the Agency and ensure that they

contain all pertinent information about the condition and evaluation results known to the organisation.

(d) Where the organisation is contracted by a commercial operator to carry out maintenance, the organisation shall also

report to the operator any such condition affecting the operator's aircraft or component.

(e) The organisation shall produce and submit such reports as soon as practicable but in any case within 72 hours of

the organisation identifying the condition to which the report relates.

145.A.65 Safety and quality policy, maintenance procedures and quality system

(a) The organisation shall establish a safety and quality policy for the organisation to be included in the exposition

under 145.A.70.

(b) The organisation shall establish procedures agreed by the competent authority taking into account human factors
and human performance to ensure good maintenance practices and compliance with this Part which shall include a
clear work order or contract such that aircraft and components may be released to service in accordance with
145.A.50.

1. The maintenance procedures under this paragraph apply to 145.A.25 to 145.A.95.

2. The maintenance procedures established or to be established by the organisation under this paragraph shall cover
all aspects of carrying out the maintenance activity, including the provision and control of specialised services
and lay down the standards to which the organisation intends to work.

3. With regard to aircraft line and base maintenance, the organisation shall establish procedures to minimise the risk
of multiple errors and capture errors on critical systems, and to ensure that no person is required to carry out
and inspect in relation to a maintenance task involving some element of disassembly/reassembly of several
components of the same type fitted to more than one system on the same aircraft during a particular mainte-
nance check. However, when only one person is available to carry out these tasks then the organisation's work
card or worksheet shall include an additional stage for re-inspection of the work by this person after completion
of all the same tasks.

4. Maintenance procedures shall be established to ensure that damage is assessed and modifications and repairs are
carried out using data approved by the Agency or by an approved Part-21 design organisation, as appropriate.

(c) The organisation shall establish a quality system that includes the following:

1. Independent audits in order to monitor compliance with required aircraft/aircraft component standards and
adequacy of the procedures to ensure that such procedures invoke good maintenance practices and airworthy
aircraft/aircraft components. In the smallest organisations the independent audit part of the quality system may
be contracted to another organisation approved under this Part or a person with appropriate technical knowledge
and proven satisfactory audit experience; and

28.11.2003

EN

Official Journal of the European Union

L 315/57

2. A quality feedback reporting system to the person or group of persons specified in 145.A.30(b) and ultimately to
the accountable manager that ensures proper and timely corrective action is taken in response to reports resulting
from the independent audits established to meet paragraph (1).

Use of the EASA Form 1 for maintenance

1. GENERAL

The certificate shall comply with the format attached including block numbers in that each block must be located as
per the layout. The size of each block may however be varied to suit the individual application, but not to the extent
that would make the certificate unrecognisable. The overall size of the certificate may be significantly increased or
decreased so long as the certificate remains recognisable and legible. If in doubt consult your Member State.

All printing shall be clear and legible to permit easy reading.

The certificate shall either be pre-printed or computer generated but in either case the printing of lines and characters
must be clear and legible. Pre-printed wording is permitted in accordance with the attached model but no other certi-
fication statements are permitted.

English and, where relevant, the language(s) of the Member State concerned are acceptable.

Completion of the certificate may be in English when it is used for export purposes, otherwise it can be completed in
the official language(s) of the Member State concerned.

The details to be entered on the certificate can be either machine/computer printed or handwriting using block letters
and must permit easy reading.

Abbreviations must be restricted to a minimum.

The space remaining on the reverse side of the certificate may be used by the originator for any additional informa-
tion but must not include any certification statement.

The original certificate must accompany the items and correlation must be established between the certificate and the
items. A copy of the certificate must be retained by the organisation that manufactured or maintained the item.
Where the certificate format and data is entirely computer generated, subject to acceptance by the Member State, it is
permissible to retain the certificate format and data on a secure database.

Where a single certificate was used to release a number of items and those items are subsequently separated out from
each other, such as through a parts distributor, then a copy of the original certificate must accompany such items
and the original certificate must be retained by the organisation that received the batch of items. Failure to retain the
original certificate could invalidate the release status of the items.

NOTE: There is no restriction in the number of copies of the certificate sent to the customer or retained by the originator.

The certificate that accompanies the item may be attached to the item by being placed in an envelope for durability.

2. COMPLETION OF THE RELEASE CERTIFICATE BY THE ORIGINATOR

Except as otherwise stated, there must be an entry in all blocks to make the document a valid certificate.

Block 1 The name and country of the Member State under whose approval the certificate was issued. This information
may be pre-printed.

Block 2 Pre-printed ‘Authorised Release certificate/EASA Form 1’.

Block 3 A unique number shall be pre-printed in this block for certificate control and traceability purposes except that
in the case of a computer generated document, the unique number need not be pre-printed where the computer is
programmed to produce the number.

Block 4 The full name and address plus mailing address if different of the approved organisation releasing the items
covered by this certificate. This block may be pre-printed. Logos, etc., are permitted if the logo can be contained
within the block.

Block 5 Its purpose is to reference work order/contract/invoice or any other internal organisational process such that
a fast traceability system can be established.

Block 6 This block is provided for the convenience of the organisation issuing the certificate to permit easy cross-
reference to the 'Remarks' Block 13 by the use of item numbers. Completion is not mandatory.

Where a number of items are to be released on the certificate, it is permissible to use a separate listing cross-referring
certificate and list to each other.

Block 7 The name or description of the item shall be given. Preference shall be given to use of the Illustrated Parts
Catalogue (IPC) designation.

Block 8 State the Part Number. Preference shall be given to use of the IPC number designation.

Block 9 Used to indicate the Type-Approved products for which the released items are eligible for installation.
Completion of block is optional but if used, the following entries are permitted:

(a) The specific or series aircraft, engine, propeller or auxiliary power unit model, or a reference to a readily available

catalogue or manual which contains such information, for example: ‘A300’.

(b) ‘Various’, if known to be eligible for installation on more than one model of Type-Approved product, unless the

originator wishes to restrict usage to a particular model installation when it shall so state.

(c) ‘Unknown’, if eligibility is unknown, this category being primarily for use by maintenance organisations.

NOTE: Any information in Block 9 does not constitute authority to fit the item to a particular aircraft, engine, propeller or auxiliary
power unit. The User/installer shall confirm via documents such as the Parts Catalogue, Service Bulletins, etc. that the item is
eligible for the particular installation.

Block 10 State the number of items being released.

Block 11 State the item Serial Number and/or Batch Number if applicable, if neither is applicable, state ‘N/A’.

Block 12 The following words in quotation marks, with their definitions, indicate the status of the item being released.
One or a combination of these words shall be stated in this block:

1. OVERHAULED

The restoration of a used item by inspection, test and replacement in conformity with an approved standard (*) to
extend the operational life.

2. INSPECTED/TESTED

The examination of an item to establish conformity with an approved standard (*).

3. MODIFIED

The alteration of an item in conformity with an approved standard (*).

4. REPAIRED

The restoration of an item to a serviceable condition in conformity with an approved standard (*).

5. RETREADED

The restoration of a used tyre in conformity with an approved standard (*).

6. REASSEMBLED

The reassembly of an item in conformity with an approved standard (*).

Example: A propeller after transportation.

NOTE: This provision shall only be used in respect of items which were originally fully assembled by the manufacturer in accor-

dance with manufacturing requirements such as, but not limited to, Part-21.

(*) Approved Standard means a manufacturing/design/maintenance/quality standard approved by the competent

authority.

The above statements shall be supported by reference in Block 13 to the approved data/manual/specification used
during maintenance.

L 315/64

EN

Official Journal of the European Union

28.11.2003

Block 13 It is mandatory to state any information in this block either direct or by reference to supporting documenta-
tion that identifies particular data or limitations relating to the items being released that are necessary for the User/
installer to make the final airworthiness determination of the item. Information shall be clear, complete, and provided
in a form and manner which is adequate for the purpose of making such a determination.

Each statement shall be clearly identified as to which item it relates.

If there is no statement, state ‘None’.

Some examples of the information to be quoted are as follows:

— The identity and issue of maintenance documentation used as the approved standard.

— Airworthiness Directives carried out and/or found carried out, as appropriate.

— Repairs carried out and/or found carried out, as appropriate.

— Modifications carried out and/or found carried out, as appropriate.

— Replacement parts installed and/or parts found installed, as appropriate.

— Life limited parts history.

— Deviations from the customer work order.

— Identity of other regulation if not Part-145.

— Release statements to satisfy a foreign maintenance requirement.

— Release statements to satisfy the conditions of an international maintenance agreement such as, but not limited
to, the Canadian Technical Arrangement Maintenance and the USA Bilateral Aviation Safety Agreement — Main-
tenance Implementation Procedure.

NOTE: The latter two statements allow the possibility of dual release against both Part-145 and a foreign maintenance requirement
or the single release by a Part-145 approved maintenance organisation against a foreign maintenance requirement. However
care should be exercised to tick the relevant box(es) in block 19 to validate the release. It should also be noted that the dual
release requires the approved data to be approved/accepted by both the Member State and the appropriate foreign State and
the single release requires the approved data to be approved/accepted only by the appropriate foreign State.

Blocks 14, 15, 16, 17 & 18: Must not be used for maintenance tasks by Part-145 approved maintenance organisa-
tions. These blocks are specifically reserved for the release/certification of newly manufactured items in accordance
with Part 21 and national aviation regulations in force prior to Part-21 becoming fully effective.

Block 19 Contains the required release to service statement for all maintenance by Part 145 approved maintenance
organisations. When non Part-145 maintenance is being released block 13 shall specify the particular national regula-
tion. In any case the appropriate box shall be 'ticked' to validate the release.

The certification statement ‘except as otherwise specified in block 13’ is intended to address the following situations;

(a) The case where the maintenance could not be completed.

(b) The case where the maintenance deviated from the standard required by Part-145.

(c) The case where the maintenance was carried out in accordance with a non Part-145 requirement.

Whichever case or combination of cases shall be specified in block 13.

Block 20 For the signature of the certifying staff authorised by the Part-145 approved maintenance organisation. This
signature can be computer printed subject to the Member State being satisfied that only the signatory can direct the
computer and that a signature is not possible on a blank computer generated form.

Block 21 The Part-145 approved maintenance organisation reference number given by the Member State.

Block 22 The printed name of the Block 20 signatory and personal authorisation reference.

Block 23 The date of signing the Block 19 release to service. (d/m/y). The month shall appear in letters e.g. Jan, Feb,
Mar etc. The release to service shall be signed at the ‘completion of maintenance’.

Please note the User Responsibility Statements are on the reverse of this certificate. These statements may be added
to the front of the certificate below the bottom line by reducing the depth of the form.

USER/INSTALLER RESPONSIBILITIES

Note:

1. It is important to understand that the existence of the Document alone does not automatically constitute authority to

install the part/component/assembly

2. Where the user/installer works in accordance with the national regulations of an Airworthiness Authority different
from the Airworthiness Authority specified in block 1 it is essential that the user/installer ensures that his/her
Airworthiness Authority accepts parts/components/assemblies from the Airworthiness Authority specified in block 1.

3. Statements 14 and 19 do not constitute installation certification. In all cases the aircraft maintenance record must
contain an installation certification issued in accordance with the national regulations by the user/installer before the
aircraft may be flown.

Appendix II

Organisations approval class and rating system

1.

Except as stated otherwise for the smallest organisation in paragraph 12, Table 1 outlines the full extent of approval
possible under Part-145 in a standardised form. An organisation must be granted an approval ranging from a single
class and rating with limitations to all classes and ratings with limitations.

2.

In addition to Table 1 the Part-145 approved maintenance organisation is required by 145.A.20 to indicate scope
of work in the maintenance organisation exposition. See also paragraph 11.

3. Within the approval class(es) and rating(s) granted by the Member State, the scope of work specified in the mainte-
nance organisation exposition defines the exact limits of approval. It is therefore essential that the approval class(es)
and rating(s) and the organisation's scope of work are compatible.

4. A category A class rating means that the Part-145 approved maintenance organisation may carry out maintenance
on the aircraft and any component (including engines/APUs) only whilst such components are fitted to the aircraft
except that such components can be temporarily removed for maintenance when such removal
is expressly
permitted by the aircraft maintenance manual to improve access for maintenance subject to a control procedure in
the maintenance organisation exposition acceptable to the Member State The limitation section will specify the
scope of such maintenance thereby indicating the extent of approval.

5. A category B class rating means that the Part-145 approved maintenance organisation may carry out maintenance
on the uninstalled engine/APU (‘Auxiliary Power Unit’) and engine/APU components only whilst such components
are fitted to the engine/APU except that such components can be temporarily removed for maintenance when such
removal is expressly permitted by the engine/APU manual to improve access for maintenance. The limitation section
will specify the scope of such maintenance thereby indicating the extent of approval. A Part-145 approved mainte-
nance organisation with a category B class rating may also carry out maintenance on an installed engine during
‘base’ and ‘line’ maintenance subject to a control procedure in the maintenance organisation exposition. The mainte-
nance organisation exposition scope of work shall reflect such activity where permitted by the Member State.

6. A category C class rating means that the Part-145 approved maintenance organisation may carry out maintenance
on uninstalled components (excluding engines and APUs) intended for fitment to the aircraft or engine/APU. The
limitation section will specify the scope of such maintenance thereby indicating the extent of approval. A Part-145
approved maintenance organisation with a category C class rating may also carry out maintenance on an installed
component during base and line maintenance or at an engine/APU maintenance facility subject to a control proce-
dure in the maintenance organisation exposition. The maintenance organisation exposition scope of work shall
reflect such activity where permitted by the Member State.

7. A category D class rating is a self contained class rating not necessarily related to a specific aircraft, engine or other
component. The D1 — Non-Destructive Testing (NDT) rating is only necessary for a Part-145 approved mainte-
nance organisation that carries out NDT as a particular task for another organisation. A Part-145 approved mainte-
nance organisation with a class rating in A or B or C category may carry out NDT on products it is maintaining
subject to the maintenance organisation exposition containing NDT procedures, without the need for a D1 class
rating.

8. Category A class ratings are subdivided into ‘Base’ or ‘Line’ maintenance. A Part-145 approved maintenance organi-
sation may be approved for either ‘Base’ or ‘Line’ maintenance or both. It should be noted that a ‘Line’ facility
located at a main base facility requires a ‘Line’ maintenance approval.

9. The ‘limitation’ section is intended to give the Member State maximum flexibility to customise the approval to a
particular organisation. Table 1 specifies the types of limitation possible and whilst maintenance is listed last in each
class rating it is acceptable to stress the maintenance task rather than the aircraft or engine type or manufacturer, if
this is more appropriate to the organisation. An example could be avionic systems installations and maintenance.

10. Table 1 makes reference to series, type and group in the limitation section of class A and B. Series means a specific
type series such as Airbus 300 or 310 or 319 or Boeing 737-300 series or RB211-524 series etc. Type means a
specific type or model such as Airbus 310-240 type or RB 211-524 B4 type etc. Any number of series or types
may be quoted. Group means for example Cessna single piston engined aircraft or Lycoming non-supercharged
piston engines etc.

11. When a lengthy capability list is used which could be subject to frequent amendment, then such amendment shall
be in accordance with a procedure acceptable to the Member State and included in the maintenance organisation
exposition. The procedure shall address the issues of who is responsible for capability list amendment control and
the actions that need to be taken for amendment. Such actions include ensuring compliance with Part-145 for
products or services added to the list.

12. A Part-145 approved maintenance organisation which employs only one person to both plan and carry out all

maintenance can only hold a limited scope of approval rating. The maximum permissible limits are:-

Appendix II

Basic Examination Standard

1.

Standardisation Basis For Examinations

1.1. All basic examinations must be carried out using the multi-choice question format and essay questions as specified

below.

1.2.

Each multi-choice question must have three alternative answers of which only one must be the correct answer
and the candidate must be allowed a time per module which is based upon a nominal average of 75 seconds per
question.

1.3.

Each essay question requires the preparation of a written answer and the candidate must be allowed 20 minutes
to answer each such question.

1.4.

Suitable essay questions must be drafted and evaluated using the knowledge syllabus in Part-66 Appendix I
Modules 7, 9 and 10.

1.5.

Each question will have a model answer drafted for it, which will also include any known alternative answers that
may be relevant for other subdivisions.

1.6. The model answer will also be broken down into a list of the important points known as Key Points.

1.7. The pass mark for each Part-66 module and sub-module multi-choice part of the examination is 75 %.

1.8. The pass mark for each essay question is 75 % in that the candidates answer must contain 75 % of the required

key points addressed by the question and no significant error related to any required key point.

1.9.

If either the multi-choice part only or the essay part only is failed, then it is only necessary to retake the multi-
choice or essay part, as appropriate.

1.10. Penalty marking systems must not be used to determine whether a candidate has passed.

1.11. All Part-66 modules that make up a complete Part-66 aircraft maintenance licence category or subcategory must
be passed within a 5 year time period of passing the first module except in the case specified in paragraph 1.12.
A failed module may not be retaken for at least 90 days following the date of the failed module examination,
except in the case of a Part-147 approved maintenance training organisation which conducts a course of
retraining tailored to the failed subjects in the particular module when the failed module may be retaken after 30
days.

1.12. The 5 year time period specified in paragraph 1.11 does not apply to those modules which are common to more
than one Part-66 aircraft maintenance licence category or subcategory and which were previously passed as part
of another such category or subcategory examination.

PART-66 AIRCRAFT MAINTENANCE LICENCE

1. An example of the Part-66 aircraft maintenance licence can be found on the following pages.

2. The document must be printed in the standardised form shown but may be reduced in size to accommodate its
computer generation if desired. When the size is reduced care should be exercised to ensure sufficient space is avail-
able in those places where official seals/stamps are required. Computer generated documents need not have all the
boxes incorporated when any such box remains blank so long as the document can clearly be recognised as the
Part-66 aircraft maintenance licence.

3. The document may be printed in the English or the official language of the Member State concerned, except that if
the official language of the Member State concerned is used, a second English copy must be attached for any licence
holder that works outside that Member State to ensure understanding for the purpose of mutual recognition.

4. Each licence holder must have a unique licence number based upon a National identifier and an alpha-numeric

designator.

5. The document may have the pages in any order and need not have some or any divider lines as long as the informa-
tion contained is positioned such that each page layout can clearly be identified with the format of the example
Part-66 aircraft maintenance licence contained herein. The aircraft type rating page need not be issued until the first
type endorsement is included.

6. The document may be prepared by the competent authority of the Member State or by any Part-145 approved
maintenance organisation in accordance with a procedure approved by the Member State and contained in the Part-
145 maintenance organisation exposition except that in all cases the competent authority of the Member State will
issue the document.

7. The preparation of any variation to an existing Part-66 aircraft maintenance licence may be carried out by the
competent authority of the Member State or by any Part-145 approved maintenance organisation in accordance
with a procedure approved by the competent authority of the Member State and contained in the Part-145 mainte-
nance organisation exposition except that in all cases the competent authority of the Member State will issue the
document with the variation.

8. The Part-66 aircraft maintenance licence once issued is required to be kept by the person to whom it applies in

good condition and who shall remain accountable for ensuring that no unauthorised entries are made.

9. Failure to comply with paragraph 8 may invalidate the document and could lead to the holder not being permitted

to hold any Part-145 certification authorisation and may result in prosecution under National law.

10. The Part-66 aircraft maintenance licence is recognised in all Member States and it is not necessary to exchange the

document when working in another Member State.

11. The annex to EASA Form 26 is optional and may only be used to include National Privileges not covered by Part-

66, where such privileges were covered by the national regulation in force prior to the implementation of Part-66.

12. For information the actual Part-66 aircraft maintenance licence issued by the competent authority of the Member

State may have the pages in a different order and may not have the divider lines.

13. With regard to the aircraft type rating page the competent authority of the Member State may choose not to issue
this page until the first aircraft type rating needs to be endorsed and will need to issue more than one aircraft type
rating page when there are a number to be listed.

14. Notwithstanding 13, each page issued will be in this format and contain the specified information for that page.

15. If there are no limitations applicable, the LIMITATIONS page will be issued stating ‘No limitations’.

16. Where a pre-printed format is used, any category, subcategory or type rating box which does not contain a rating

entry shall be marked to show that the rating is not held.
