Published date: 4 February 2014


Civil Aviation Authority advisory circulars contain information about standards, practices, and procedures that the Director has found to be an acceptable means of compliance with the associated rule.

An acceptable means of compliance is not intended to be the only means of compliance with a rule, and consideration will be given to other methods of compliance that may be presented to the Director.   When new standards, practices, or procedures are found to be acceptable they will be added to the appropriate advisory circular.

An advisory circular also includes guidance material to facilitate compliance with the rule requirements.   Guidance material must not be regarded as an acceptable means of compliance.


The advisory circular provides acceptable means of compliance for issue of aircraft maintenance licences, certificates and ratings and the privileges and limitations of those licences, certificates and ratings.

Related Rules

This advisory circular relates specifically to Civil Aviation Rule Part 66.

Change Notice

Revision 2 amends the reference to annual review of airworthiness to the current term review of airworthiness .


Part 66, Aircraft Maintenance Personnel Licensing, prescribes the rules relating to the issue of licences, ratings, certificates, and authorisations issued by the Director.

This advisory circular provides information about some of the rules in Part 66 and describes the policies of the CAA in administering those rules. Because some of the rules are obvious in their application, not all rules are detailed in this circular.

This advisory circular also specifies the examinations that are required for the issue of documents under Part 66.


Readers should refer to Part 66 for references to the rule. Rule numbers have been used here to identify paragraphs that relate to those rules.

66.1       Applicability

Part 66 prescribes the specific requirements for the issue of aircraft maintenance engineer licences, ratings, certificates of maintenance approval, and inspection authorisations. The Rule Part also describes the privileges and limitations of these documents. It is important that this advisory circular is read in conjunction with the rule.

66.7       Application for licences, certificates, and ratings

Applications for licences, ratings, certificates, and authorisations should be completed on the applicable application form and forwarded to—

Personnel Licensing
Civil Aviation Authority
PO Box 31441
Lower Hutt   5040

The following application forms are available from the CAA Web Site, under the heading – Maintenance link)

AME Licence and Category issue                      CAA 24066/01

Certificate of Maintenance Approval issue         CAA 24066/03

Overseas AMEL recognition                             CAA 24066/04

Certificate of Inspection Authorisation issue      CAA 24066/10

The appropriate fees, as prescribed by the Civil Aviation Charges Regulations (and specified on the applicable application form) should be enclosed with the application.

Where practical experience details are required they should be documented in a suitable Practical Training Record (PTR) and be as complete and detailed as possible to allow prompt assessment of the application.

Applicants for additional categories or ratings, should forward their existing licence or certificate with the application.

66.9       Issue of licences, certificates and ratings

The appendices to this circular contain information on the following:

· Appendix 1 - description of AME Licence category groups and ratings

· Appendix 2- lists the various ratings

· Appendix 3- describes the Category demarcations

This rule requires the applicant to satisfy the Director that the following requirements are met—

66.9(a)(1) - Fit and proper person test

Holders of an aviation document must pass a fit and proper person test. Initial applicants for licences or certificates issued under this part will be required to complete a Fit and Proper Person Questionnaire - CAA 24FPP,that meets the requirements of this test.

The criteria for the fit and proper person test are in section 10 of the Civil Aviation Act 1990. Section 11 of the Act defines the rights of individuals, and requires a set procedure in case of adverse determinations.

66.9(a)(2) - English language test

The applicant's ability to speak, read, and write the English language will be assessed during the written and oral examinations carried out to qualify for the licence or certificate.

66.9(a)(3) - Eligibility requirements

This refers to the requirements in rules 66.53, 66.103, 66.153, and 66.203; and relate to examinations and practical experience.

The acceptable method of demonstrating completion of suitable practical experience is to submit a Practical Training Record (PTR). This should be set out so the experience is readily identifiable to that applicable licence/category/rating that is being applied for.

66.9(a)(4) - Interest of aviation safety

The granting of a licence or certificate must not be contrary to the interests of aviation safety. To satisfy this requirement the personal records of each applicant for a licence, or certificate, will be reviewed. The Director can only review records that are in the possession of the Authority.

66.9(b) - Foreign AME Licence recognition

Applicants for the grant of licences, ratings, or certificates, issued on the basis of a current licence or certificate issued by a foreign ICAO Contracting State, should complete application form CAA 24066/04. Reference should be made to this form and the CAA web site for the application requirements.

The application will be assessed:

· to ensure that the licence or certificate has been issued by an ICAO Contracting State, where CAA understands that state’s licensing system and that state’s system meets the requirements of Annex 1 to the ICAO Convention;

· to ensure that the document is valid and current, as part of this process the issuing State should be able to verify this to CAA;

· to determine the extent of, any limitations, and rating coverage; and

· to determine which AMEL examinations are required to be passed. As a minimum this will include Human Factors (code 17) and both the Air Law, written and oral examinations (codes 20 and 21).

Applicants will be required to complete the Fit and Proper Person Questionnaire - CAA 24FPP, and satisfy the Director that the issue of the document is not contrary to the interests of safety.

66.9(c) - Australian licence recognition

Holders of licences and certificates issued by the Civil Aviation Safety Authority of Australia who apply for recognition in New Zealand are required to pass examination code 20 – Written Air Law.

66.11    Duration of licences and certificates

A licence is issued under Part 66 for the lifetime of the holder. It is, therefore, important that licence and certificate holders advise the Director when they change their personal details, such as address or name. This is a requirement under section 8(3) of the Civil Aviation Act 1990.

Licences, certificates of maintenance approval, and certificates of inspection authorisation will need to be forwarded to the Director with applications for amendment, such as rating issue or renewal. Amended documents cannot be issued until the original document has been received.

This return-of-documents requirement is to prevent the possibility that old licence documents may be mislaid by their owner and then used fraudulently by another person.

Certificates of maintenance approval, granted to the principal constructor of an amateur-built aircraft, may be issued for up to 5 years. Certificates of maintenance approval, granted for other purposes, may be issued for any period of up to 2 years. The period of issue will depend on the purpose for which the certificate has been issued. Where an approval is issued to allow practical experience to be gained it will be issued for the minimum time required for that experience.

Certificates of inspection authorisation may be issued for up to 5 years.

Any licence, certificate of maintenance approval, or certificate of inspection authorisation that has been suspended or revoked is to be forwarded to the Director. Forthwith means without delay, having regard for the circumstances of the holder.

Lost or stolen documents

If a licence or certificate is lost, or is stolen, the document may be replaced. You will need to submit to the director a completed form CAA 600, pay the appropriate fee and produce written evidence that the loss, or theft, has been reported to the local Police.

66.13    Examinations

This rule requires examination candidates to produce documented proof of their identity for examinations that will lead to the issue of a licence, rating, or certificate issued under Part 66. Acceptable methods of proving identity include—

· Passport;

· New Zealand or foreign driver’s licence;

· New Zealand or foreign pilot’s licence ;

· Birth Certificate;

· New Zealand CAA Airport Identity Card; or

·  any similar document acceptable to an Examination Conducting Officer.

The minimum pass mark for all written examinations is 70%. Applicants should ensure that they retain course certificates or examination result notices until the licence, rating, or certificate the examination or course relates to, has been issued.

Written examination passes are valid for the lifetime of the holder, except for the Written Air Law examination (code 20) which is valid for 5 years. This means an applicant must apply and have the licence issued within 5 years of completing the Air Law examination (code 20). If an applicant fails to have the licence issued within 5 years of sitting the Air Law examination, that subject must be re-sat and passed.

Before sitting the Oral Air Law examination (code 21) the applicant must have completed all written examinations required for the licence issue and have completed the required practical experience listed in rule 66.53(a)(4).

If the Oral Air Law examination (code 21) is failed 3 times in succession a three-month stand down period will apply from the date of the last attempt, this is to allow the candidate to suitably review the subject material prior to a further sitting.

66.53(a)(3) - Oral Air Law Examination

Rule 66.53(3) requires the successful completion of an oral examination covering the applicant’s understanding and practical application of the duties and responsibilities exercised by the holder of an aircraft maintenance engineer's licence.

The Oral Air Law examination, code 21, is acceptable for this. A pass grade in this examination is required before the initial issue of an aircraft maintenance engineer’s licence in any category.

66.53(a)(4) - Practical experience, training

Licence issue experience

Practical aviation experience requirements for licence issue vary depending on the method by which the applicant has gained training—

· An engineer that has not undertaken any formal engineering training but has completed the required examinations through self-study methods will be required to complete 60 months of practical aviation engineering experience;

· An engineer who has completed a traineeship in an aviation technical trade will be required to complete 48 months of practical aviation experience. These 48 months includes the time spent in formal technical training. The training could comprise a number of formal block courses or a continuous non-integrated training course. RNZAF training is considered to meet this requirement;

· Engineers who have successfully completed a traineeship in an allied engineering trade require 36 months of aviation related practical experience. This is in addition to any practical experience gained when qualifying for the allied trade qualification. An allied trade is considered to be a technical trade similar in nature to aviation trades such as, automotive engineering, general engineering, and electronic engineering; and

· Engineers that undertake a course of training conducted by a certificated Part 141 organisation that holds the appropriate E2 rating will need to show 36 months of aviation related experience that includes the time spent on integrated aviation training. The course will need to include supervised training and practical experience.

Category experience

A period of 24 months of practical experience is required relating to the specific category being sought. For example, an applicant for a powerplant category is required to show 24 months of powerplant maintenance experience. The balance of the required experience may consist of experience in any of the other categories.

Practical experience for two or more categories may be gained concurrently if the nature of the job allows for this. For example, typically in a general aviation hangar a tradesperson would work on both aeroplane and powerplant category type maintenance concurrently.

Rule 66.53(c)(2) provides for an engineer who has exercised the privileges of an aircraft maintenance engineer licence for 10 years or more, the holder is entitled to an additional category of licence if he or she has completed 12 months of appropriate experience.

Documenting practical experience

Practical experience for the issue of an AME Licence and Categories should be documented in a suitable Practical Training Record (PTR). This should be set out or highlighted so the experience is readily identifiable to the applicable licence and/or category that is being applied for.

CAA has produced an acceptable PTR in conjunction with the Aviation, Tourism and Travel Training Organisation (ATTTO). This can be purchased from ATTTO - details for purchasing are on the CAA web site, under the heading Maintenance link)  - or the ATTTO web site – link)
Engineers are not required to use the ATTTO / CAA PTR, but the format of any acceptable PTR should have the following features:

· provide an overview of experience /employment in the aviation industry, detailing relevant qualifications, training and courses;

· list specific tasks completed, being countersigned by a supervising LAME; and

· details of the dates and the specific aircraft or components worked on.

As a guide, typical PTR format have been included in Appendix 5.

66.55     Privileges and limitations

To exercise the privileges of an aircraft maintenance engineer licence the holder must be appropriately rated. A list of ratings is included as Appendix 2.

The demarcations between each licence category are published as Appendix 3.

Part 145 Demarcation

Rule 43.54 details the maintenance that must be carried out under the authority of, and according to the provision of, a maintenance organisation certificate issued under Part 145. Aircraft and aircraft components maintained under this Part may only be released to service by a person authorised to do so by the certificated maintenance organisation. Ratings covering aircraft and aircraft components that are required to be maintained by a Part 145 maintenance organisation may be added to an aircraft maintenance engineer licence issued under Part 66.

These ratings alone do not provide release-to-service privileges – such privileges are conferred by an authorisation issued by the Part 145 certificated maintenance organisation.

These ratings—

· have been retained as a method of indicating examination and practical experience qualification in a transportable manner; and

· are restricted to aircraft, or system, type and component groups and are described in Part 66 Appendix B.2, and in Appendix 2.

66.55(b) - Familiarity

Before exercising the privileges of an aircraft maintenance engineer licence the engineer must be familiar with the specific aircraft or aircraft component being maintained.

This is applicable to all ratings, be it a Group rating or Type rating.

For Group ratings, the engineer should be familiar with the specific types with the Group.

For Type ratings, the engineer should be familiar with the specific variants or models with the type rating.

E.g. - Powerplant Type Ratings, where the type may cover FADEC variants. The engineer would need to have completed specific training on the FADEC system or models.

The engineer should have a thorough knowledge of the appropriate maintenance manual, and other ICAs, and understand the acceptable standards and practices required by Part 43. The engineer should have practical experience of the task to be performed, or of a task of similar nature.

66.55(c) - Special Test Equipment

When using special test equipment to carry out the additional privileges specified in Part 66 Appendix C, the licence holder is required to have received appropriate training and have evidence of that training on the test equipment. This evidence may be a certificate, or letter, from:

· an appropriately rated aircraft maintenance engineer licence holder;

· a person authorised to conduct training on the equipment under Part 141; or

· the test equipment manufacturer or their technical representative.
Subpart C - Aircraft Maintenance Engineer Ratings

66.103  Eligibility requirements

To be eligible for the grant of an aircraft maintenance engineer licence rating, the applicant must hold a current aircraft maintenance engineer licence and meet the practical experience and examination or course requirements detailed below.

66.103(2) - Practical experience

The rule specifies a minimum time of 6 months practical experience on the type or group of aircraft or aircraft components. This should be completed within the immediate three years before application to demonstrate familiarity and currency.

Documenting experience - Practical Training Record (PTR)

To demonstrate that six months practical experience has been completed for the issue of a rating, the experience should be documented in a suitable Practical Training Record (PTR).  This should be set out, or highlighted so the experience is readily identifiable to the applicable rating that is being applied for.

CAA has produced an acceptable PTR in conjunction with the ATTTO. This can be purchased from ATTTO - details for purchasing are on the CAA web site, under the heading Maintenance link)  - or the ATTTO web site – link)

Engineers are not required to use the ATTTO / CAA PTR but the format of any acceptable PTR should list the specific tasks completed, being countersigned by a supervising LAME, along with details of the dates and the specific aircraft or component.

As a guide, a typical group rating PTR page has been included in Appendix 5.

Only experience specific to the rating(s) sought should be included, or highlighted in some way in the PTR. The range and depth of the relevant experience should be readily evident from an assessment of the PTR.

Rating experience requirements

Practical experience should comprise a broad cross section of maintenance tasks at both Line and Base (Hangar) Maintenance Levels and should be across all relevant systems (appropriate ATA Chapters) for the category(s) applying for. 

Typically this should include:

· Completing all aspects of a number of line and base level routine inspections;

·  For transport category type rated aircraft this should include a minimum of three; and different C level type checks:;

·  A broad cross section of the following representative tasks on the various aircraft systems:

· trouble shooting;

· repair;

· adjustments and rigging;

· component and module changes;

· functional/operational checks; and

· use of special tooling and test equipment.

Reference should be made to Appendix 4 that lists typical tasks by aircraft systems.

Group Ratings

As a guide, typical acceptable practical experience for group ratings should include the following practical experience:

Aeroplane and rotorcraft categories

· Minimum of three periodic inspections, including avionic systems;

· Minimum of two aircraft weighings, or weight and balance calculations for the first aeroplane and the first rotorcraft rating;

· Rectification of defects and component changes including avionic components;

· Compass compensation for the first rating; and

· Functional testing and servicing of aircraft systems.

Powerplant category

· Minimum of three periodic inspections;

· Rectification of defects and component changes; and

· Functional testing and servicing of powerplant systems, including propulsion engine ground running.

Note: Applicants for the Group 2 powerplant rating must hold the Group 1 powerplant rating.

Electrical category

· Periodic inspection and testing;

· Defect analysis and rectification, including component changes; and

· Modification installation.

Instrument category

· Periodic inspection and testing;

· Defect analysis and rectification, including component changes;

· Modification installation; and

· Compass compensation for the issue of the first rating.

Radio category

· Periodic inspection and testing;

· Defect analysis and rectification, including component changes; and

· Modification installation.

Lighter-than-air category

· Periodic inspections; and

· Fabric repairs and other rectification.

Note: If insufficient experience is shown for a group rating and this is due to the inability of the applicant to be exposed to more than one type within a group, the applicant may apply to have that type issued as a restricted type rating within a group. It is not intended for this to be usual practice, but the provision is included for cases of genuine need. If a genuine need cannot be substantiated then the application will be declined.

Type Ratings

For the issue and assessment of Type Ratings practical experience and any specific OJT should be documented in an appropriate aircraft and/or powerplant specific type rating PTR that details/sets out the experience under the relevant systems (ATA Chapters). 

For transport category aircraft the PTR will normally be developed by the Part 145 Certificated Maintenance Organisation as part of their company authorisation procedures and should clearly detail or set out an acceptable cross section of specific tasks across the relevant systems that must be completed prior to the issue of a company authorisation.

Type rating PTRs may also be developed by a Part 141 aviation training organisation for their type rating courses.

Component Ratings

Applicants for the component ratings, Group 7 of each category, should show 6 months of practical experience gained on the overhaul or repair of specific components. Where the rating applies to a group of components the PTR should demonstrate that the experience has been gained on a wide selection of components from within the category. If this cannot be demonstrated a restricted rating may be issued limiting the range of component types. For example, restricted to alternators only.

66.103(3) - Examinations and courses

Type Ratings Courses

Type ratings require the completion of an approved or acceptable course. A course must be:

· conducted by a Part 141 aviation training organisation or a Part 145 maintenance organisation certificated (rule 145.11(a)(10)) with the appropriate E1 rating; 

· conducted by the manufacturer of the applicable aircraft or component; or

· approved by the competent authority of a foreign ICAO Contracting State.

Additionally, courses should:

· be developed/packaged to an industry recognised  standard such as - ATA Specification 104 - Guidelines for Aircraft Maintenance Training - Level III (Line and Base Level Maintenance), or an equivalent standard;

· cover all the relevant systems (ATA chapters) for the privilege of the category of licence;

· cover the series of aircraft or powerplants that the rating provides privilege for; or

· cover a competency assessment element such as a technical oral.

Type rating courses should be completed within 2 years to ensure familiarity and currency on type. If more than 2 years has expired since course completion, the currency of type course may be satisfactory if the holder can show continuous or significant recent practical experience on the type since completion of the course.

In cases where approved courses are not available and the provisioning of an oral or written examination is within the capabilities of CAA or ASL, an examination may be conducted by ASL.

Technical Oral

The purpose of the technical oral is to establish the engineer’s technical competence relevant to the privileges of the type rating. That is, the engineer understands more than the just ‘nuts and bolts’ or theory of operation of the relevant powerplant or airframe, and can apply the knowledge from the course, to the maintenance requirements that they can be expected to perform, and certify for, in operation and maintenance.

This may be conducted by the applicant’s Part 145 Maintenance Organisation as part of their company authorisation procedures, or alternatively by a Part 141 Training School.

Note: As part of the requirements for a Part 145 company authorisation to be issued, the technical competence for the scope of the authorisation should be examined by an appropriate senior person within the company. [Refer Rule 145.60(e)(1)]

Where the course is conducted by an foreign course provider, that is approved by a another ICAO contracting state, the technical oral may be conducted by the approved training provider using CAA guidelines for the content of the technical oral, these can be obtained by contacting CAA Personnel Licensing.

Group Ratings

Group ratings require the completion of acceptable rating examinations. Acceptable examinations for Group Ratings are detailed in Appendix 1.

Should an acceptable course be available covering a specific rating group, or individual aircraft in Aeroplane Category Group 5, the applicant may qualify for the rating by successfully completing the approved course and meeting the practical experience requirements. Note: Applicants should check with CAA before attending a course to ensure it is acceptable

Some specific Aeroplane Category Group 5 type ratings examinations that are available through ASL are listed below:

Group 5 Ratings

Group 7 Component Ratings

Group 7 component type rating qualification may be met by either an approved or acceptable course, or acceptable rating examination.

The Group 7 type rating qualification is also dependent on the applicant passing the prerequisite component overhaul examination that relates to the appropriate category. These examinations are in addition to the basic examinations detailed in 66.53.

The specific rating examinations are detailed in Appendix 1

Subpart D - Certificate of Maintenance Approval

66.153  Eligibility requirements

The certificate is issued to suitably qualified persons to permit the performance of maintenance and the release to service of aircraft or aircraft components within the limitations annotated on the certificate. Certificates of maintenance approval are not issued as a replacement document for an aircraft maintenance engineer licence.

Restrictions may be placed on the certificate that include the limiting of privileges to specific inspection levels or specific components, or require the direct supervision by a fully qualified person. For the issue of a certificate of maintenance approval the rule requires the applicant to—

· provide evidence of appropriate practical experience; and

· hold a pass in acceptable examinations or an approved course, as appropriate.

Examination requirements may include the full suite of examinations required for the issue of an aircraft maintenance engineer licence or they may be any lesser number that the Director may determine. This will depend on the extent of the privileges to be granted, the technical background of the applicant, and the extent of the applicant's aviation related practical experience.

Amateur-built aeroplanes

In the case of amateur-built aeroplanes issued with a special category, experimental airworthiness certificate, the primary constructor will be required to undertake a minimum number of examinations.

This is based on the assessment that the education process involved in the construction of the aircraft is considered an acceptable level of knowledge on aircraft of that construction type. The examination (subject 180) will cover maintenance requirements, and Air Law. If weight and balance, and compass compensation, privileges are required, further examination on these subjects will be required.

The minimum requirements for an applicant who is not the primary constructor of an amateur-built aircraft are either:

· to complete examination codes 02, 03, 04 07, 20 and 21. (In addition, subject 16 is required for compass compensation privileges); or

· complete an acceptable course and examination (subject 180).

Specific Maintenance Tasks

The minimum examination standard required for an unlicensed engineer is either:

· a successful pass of a composite examination covering the technical aspects of the certificate of maintenance approval coverage and Air Law; or

· an approved course covering the technical aspects and a pass in an acceptable Air Law examination.

Practical Experience for LAME

To gain the full practical experience required for a rating, rule 66.155(b)(1) provides for a LAME to be eligible for issue of a certificate of maintenance approval. The prerequisite is that the examination or type-course requirements for the rating have been met and a minimum acceptable level of practical experience has been gained already.

The practical experience required before the issue of a certificate of maintenance approval will vary, depending on the limitations to be applied to the certificate. The following should be considered when demonstrating appropriate practical experience of aircraft or aircraft component maintenance to gain certificate issue—


Experience levels should include periodic inspections, defect analysis and rectification, component replacement, servicing, and functional testing.


Performance of maintenance on the specific aircraft or component covered by the certificate of maintenance approval, whilst under the supervision of a fully qualified person being—

· a rated aircraft maintenance engineer;

· an approved training organisation;

· a manufacturer’s technical representative; or

· a foreign operator approved by the competent authority of that State–

may be acceptable as grounds for a reduced level of required practical experience for certificate issue. This supervision should be carried out on site during maintenance tasks, remote supervision is not acceptable.

Similar existing rating coverage

Evidence of limited experience on type, plus evidence of experience or a rating on similar aircraft or aircraft components may be acceptable grounds for a reduction in the required practical experience for certificate issue. For example - a turbine engine of an earlier model that has the same basic technology but different components.

New aircraft introduction

Due to the introduction of a new type of aircraft or aircraft component new ratings have to be issued or gained. The necessary experience period is accommodated by the Director issuing certificates of maintenance approval in the interim.

When a certificate of maintenance approval is required, the individual, or organisation, introducing the aircraft or aircraft component should submit a schedule of intended practical training or OJT to CAA. This will be assessed for acceptance before commencement of the training.

Subpart E - Certificate of Inspection Authorisation - (IA)

66.203  Eligibility requirements

To be eligible for a certificate of inspection authorisation the applicant must meet the requirements of rule 66.203. The following point should be noted—

· The applicant must hold a type rating on a current aircraft maintenance engineer licence.

Rule 66.203(3) requires that an examination in airframe overhaul, acceptable to the Director has been passed by applicants for an inspection authorisation—

· for those that held an aircraft maintenance engineer’s licence on 1 April 1997, examination code 09 is acceptable for this purpose;

· for those who were not the holder of an aircraft maintenance engineer's licence on 1 April 1997, and who hold examination credits for codes 03 and 04 issued before 1 June 1997 shall also sit and pass examination code 09; and

· those who did not hold an aircraft maintenance engineer’s licence on 1 April 1997 and who hold examination credits for codes 03 and 04 issued after 1 June 1997, will have met the requirement in respect to an examination covering airframe overhaul.

The curriculum for examination code 03 and 04 encompasses the content of examination code 09 after this date.

The course of instruction in rule 66.203(4) is an IA Initial Issue Course that is specific to the certificate of inspection authorisation and is conducted by the Director, or a Part 141 training organisation.

66.205  Privileges and limitations

The IA certificate entitles the holder to:

· perform and certify the review of airworthiness in accordance with Part 43 Subpart D; and

· certify conformity with technical data after the completion of major modifications and major repairs in accordance with Part 43 Subpart E.


The rule does not specifically require that the holder of a certificate of inspection authorisation is rated on each aircraft that the holder performs a review of airworthiness on.

However, similar to the familiarity requirements of rule 66.55(b) to exercise the privileges of the AME Licence, and rule 43.53(1) for the performance of all maintenance, the holder of a certificate of inspection authorisation must be familiar with the specific aircraft type to perform a review of airworthiness. Without being familiar, an IA cannot be reasonably assured that all the requirements for the performance of the review of airworthiness have been meet.

Experience over the 10 years since the IA certificate has been introduced has demonstrated that IAs who are not familiar on type cannot perform a review of airworthiness to an acceptable standard to meet the requirements of Rule Part 43 Subpart D.

66.207  Recent experience requirements

This rule prescribes the recent experience requirements concerning the certificate. It is emphasised that performing the routine or 100-hour inspection does not count towards maintaining recent experience for a certificate of inspection authorisation.

Rule 66.11 provides for a certificate of inspection authorisation to be issued for a period up to 60 months. To gain a new certificate of inspection authorisation the holder should apply to attend a CAA IA Renewal Course. Applicants should contact the CAA at least 90 days before expiry of the certificate to ensure a position on a course is available.

APPENDIX 5 - Acceptable PTR format

Documenting practical experience

Practical experience for the issue of an AME Licence, Categories and Ratings should be documented in a suitable Practical Training Record (PTR).

The format of any acceptable PTR should have the following features:

· a  section that provide an overview of experience /employment in the aviation industry, detailing relevant qualifications, training and courses

· an experience record section that list specific tasks completed, and:

o details the dates and the specific aircraft or component worked on.

o is countersigned by a supervising LAME

Example of experience record page

Below is an example of the typical format that should be used in the experience record section to document practical experience.

Experience should be recorded in a separate section for the appropriate rating group or specific type rating of the relevant category section.

There should be sufficient detail to describe the task to allow an assessment to see that a range of various maintenance tasks have been completed for the unit standard (U.S.), category, or rating being applied for.

In the ‘ Details of maintenance task’ column indicate one of the following actions has been carried out:

(P) - Personally performed the task

(A) - Taken an active interest in

(T) - Received instruction or on the job training

 The performance verbs used in the basic examination syllabuses are as follows:

Topic Numbering

Each syllabus is set out by topics (except for subject 18), every main topic in each syllabus is divided into sub-topics then into sub-sub-topics and, where applicable, paragraphs. The three-digit sub-sub-topic numbers shown in the left hand column of the syllabus table are used in the ‘knowledge deficiency reports’ (KDRs) to provide feedback on individual examinations.

Objective description

The middle column of each syllabus table objectively describes each sub-sub-topic by plainly stating its subject matter and the type of performance or activity required. The objectives are intended to be simple, unambiguous, and clearly focussed, outcomes to aid learning.

Knowledge levels

The right hand column of the syllabus table specifies the knowledge level for the sub-topic headings. The levels indicate the depth of knowledge required and are defined as follows:

LEVEL 1:           A familiarisation with the principal elements of the subject.

LEVEL 2:           A general knowledge of the theoretical and practical aspects of the subject.

                        The applicant should have the ability to apply their knowledge.

LEVEL 3:           A detailed knowledge of the theoretical and practical aspects of the subject.

                        The applicant should have the capacity to combine and apply the separate elements of knowledge in a logical and comprehensive manner.

Note that the knowledge levels indicate the depth of knowledge required NOT its safety importance.
