This AAC specifies the requirements for the grant of an Aircraft Maintenance Engineer Licence

and the endorsement of additional ratings to a licence in the engine category. It is to be read in

conjunction with CAO Section 100.90 Issue 3 and corresponding sub-sections of CAO Section

100.92 Issue 3.

2. Definitions (Refer to CAO Section 100.92 sub-section 2)

Dry Running Engines. There are no regulations or orders which preclude personnel holding

licence categories other than the engine category from motoring the engine. Personnel who have

a requirement to motor engines would need to be qualified on type and appropriately trained to

do so. To develop the training and conduct the assessment the methodology detailed within the

Transit Authorisations AWB 02-4 can be utilised.

Note 1: Refer to Section 6 titled Examination Requirements. In particular, please note the

information under the heading Mandatory training Course – Group 21 and 22.

Note 2: Currently, for licensing purposes, all the Garrett (AlliedSignal) TPE 331 dash models

are classified as a single series rating. This classification has been reviewed, and it is

considered that there are sufficient differences between the TPE 331-14 dash model and the

remainder of the TPE 331 dash models (below -14) to warrant them being separated into two

separate ratings. These new ratings will be endorsed on AME licences as follows: Garrett TPE

331 series to -13 (The series to -13 includes pre-Century engines) and Garrett TPE 331-14.

Holders of Garrett TPE 331 Series rating will be required to provide evidence of experience

and training to determine how their licence endorsements will be amended. Typically, a

LAME who has not had training on the TPE 331-14 will only be granted the series to TPE 331

Series to -13 rating. Conversely, LAMEs who can only provide evidence of training experience

on the TPE 331-14 will only be granted the TPE 331-14. To be granted both ratings a LAME

will have to provide evidence of training and experience on both.

The upgrading of the Garrett TPE 331 licence endorsements will occur at the next licence

renewal with no additional charge to the LAME beyond the licence renewal fee. At this time,

LAMEs will be required to substantiate their claim to either/both endorsements as applicable.

Should any LAME require to have their licence upgraded before the licence expiry date, an

additional charge for entering the endorsement(s) will be incurred. Once again, substantiation

for either or both of the endorsements will be required before entry upon the licence.






Table 1 continued Notes - Piston Engines and Gas Turbine Engines in Aeroplanes and

Airships Classified as Group 21

In the interim period where Garrett TPE 331 licences have not been upgraded, Garrett TPE

331 rated LAMEs should be aware that they must not certify for maintenance on Garrett TPE

331 series to -13 models OR TPE 331-14 models, as applicable, unless they have had

approved training and experience.

Note 3: The GE CF34 Series Group 21 rating has been superseded by two new ratings. The

GE CF34 Series rating issued on existing AME licences will be removed and replaced with the

GE CF34-3 (CL600-Series) Group 21 rating allowing certification of maintenance on the GE

CF34-3 fitted to the CL600-Series aircraft only. To obtain the GE CF34-3 (CRJ 100/200)

Group 21 rating, the applicant must complete appropriate approved training.

Note 4: Group 21 ratings for PW4000 (B747-400) and PW4000 (B767) may be granted on the

basis of adequate experience gained on the PW4000 in one of these aircraft provided the

applicant holds an engine rating for the other aircraft type and all other criteria including

differences training are met. For example an applicant who holds an RR RB211 (B747-400)

rating may be granted both PW4000 (B767) and PW4000 (B747-400) ratings on the basis of

adequate experience gained on the PW4000 installed in the B767 only with no experience on

this engine in the B747-400.

Note 5: CFM 56 (B737) Group 21 Ratings With the introduction of the B737-NG aircraft into

Australian operations there is a need to clearly indicate the privileges of the Engine Group 21

CFM56 ratings. Therefore, two changes have occurred: the old CFM 56 Series (B737) rating

has been changed to read CFM 56 (B737-300/400). This rating will cover the CFM 56 engine

installed in B737-300/400 aircraft only. A new rating CFM 56 (B737-6/7/8/900) has also been

introduced. This rating will cover the FADEC controlled CFM56-7B in the B737-NG series of

aircraft only.

Licences containing the old rating will be changed at the next renewal or re-issue to reflect the

change to that rating. Please Note: There is NO change to the privileges of this rating.

A person who holds CFM 56 Series (B737) rating, now identified as CFM 56 (B737- 300/400)

will need to complete a CASA approved course listed in AAC 9-4 or 9-5 and complete an SOE

covering the CFM56 engine and the B737-600/700/800/900 installation to be granted the

CFM 56 (B737-6/7/8/900) rating. Details of this training and SOE requirements will be

developed when required. Similarly, a person who holds the CFM 56 (B737-6/7/8/900 will

need to complete a CASA approved course listed in AAC 9-4 or 9-5 and complete an SOE

covering the CFM 56 engine and the B737-300/400 installation to be granted the CFM 56

(B737-300/400). Details of this training and SOE requirements will be developed when

required.

Note 6: The –400 (910K) refers to the B747-438 aircraft fitted with the auxiliary fuel tank in

the forward cargo compartment and introduced into the Qantas fleet late 2002. This aircraft

has other modifications that have allowed the aircraft to operate at a higher MTOW of

910,000 lbs.

5. Experience Requirements for the Grant of a Licence or

Endorsement of a Rating

The minimum experience time period required for the grant of a licence is four years aircraft

maintenance or aircraft component maintenance. The four years maintenance experience

includes two years aircraft maintenance experience in the category being applied for.

In addition to the four general and two years category experience, the applicant also needs to

have satisfied the Schedule of Experience (SOE) requirements for the Group being applied for.

The minimum practical experience required for the grant of a licence or the endorsement of an

additional rating is specified as follows:

(a) For engines classified as Group 21/22 the minimum practical experience is specified

within this AAC (Table 2) and available on the CASA website titled “Schedule Of

Experience Engine 21, 22. Minimum practical experience requirements may also be

specified within an approved Accelerated Training or Practical Consolidation

Training (PCT) Program.






(b) For engines/systems classified Groups 1, 2 and 3 the minimum practical experience is

specified within this AAC (Table 4) and in a document published by CASA titled

“Schedule Of Experience Engine 1, 2, 3”.

If the information within the AAC is found to conflict with that provided within SOE documents

then the AAC is to be taken as the authoritive document. The experience reductions detailed

within the tables are only a guide to the assessing AWI. If the complexity of an aircraft or

aircraft group being used as the basis for a reduction is not comparable to the aircraft or aircraft

group being sought, then the AWI may vary the experience reduction applied accordingly.

Because of these uncertainties LAME’s are encouraged to have their particular situation assessed

by an AWI prior to compiling their SOE.

Only central office AWI may assess SOE reductions applicable to:

(a) Competency Technical Category applicants (overseas & current/discharged military

personnel who have been employed as aircraft engineers);

(b) accelerated training program applicants; and

(c) practical consolidated training applicants.

When determining the minimum hours an individual will require for Groups 21/22 SOE,

reference is to be made to Tables 1 and 2. Table 1 titled “Schedule Of Experience Complexity

Comparison For Groups 21/22", lists engine types which are considered to be of similar

complexity. Applicants should first consult this table to establish which “List” includes the

engine for which they seek a rating. Following this, applicants should consult Table 2 titled

“Engine Base Hours Requirement”. The appropriate hours in Table 2 are then transcribed into

the Schedule of Experience (SOE). For the grant of an additional Group 21/22 Type rating, the

minimum hours set out in Table 2 may be reduced. Refer to Table 3 titled “Rating Reduction” to

identify the reduction that may be claimed.

When determining the minimum hours an applicant will require for Groups 1, 2 and 3 engine

ratings, reference is to be made to Tables 4 and 5. Table 4 provides applicants the base hours

required and Table 5 provides applicants with reductions that may be applicable to their own

situation.However, it should be noted that the final decision to grant a reduction rests with the

airworthiness inspector at the time of processing the licence application.

Experience Requirements - B737-300/400, B737-600/700/800/900, CFM56 (B737-3/400) and

CFM56 (B737-6/7/8/900)

There are many similarities and many differences between the B737–300/400 and the B737–

6/7/8/900 aircraft and associated engines. These raise questions related to the information set

out in the AACs concerning SOE requirements. This document is intended to answer those

questions and provide guidance to CASA AWIs assessing rating applications. Maintenance

Personnel Licensing (MPL) Section provides the following comments and recommendations.

The total of the recommended minimum hours in the nominated ATA Chapters in the tables

below are not equal to the minimum recommended hours for the category. This is deliberate.

The difference in hours can be made up with experience in any applicable ATA Chapter

provided the minimum hours and emphasis in the nominated Chapters are met.






Holders of ratings for both airframes/engines seeking ratings for other types:

The differences between these aircraft and engines allow some additional reduction in SOE

requirements in the airframe and engine category for an applicant for another rating, e.g. B747-

400 or RR RB211(B747-400), but the similarities do not allow 25% reduction for each rating.

The following recommendations are in addition to the reductions available by virtue of other

ratings up to a maximum reduction of 75%.

MPL recommends that a total of 35% reduction be allowed to holders of both the B737-300/400

and the B737-600/700/800/900.

MPL recommends that a total of 35% reduction be allowed to holders of both the CFM56

(B737-3/400) and CFM56 (B737-6/7/8/900).

For an applicant who does NOT hold a rating for the B737-300/400 or CFM56 the minimum

recommended SOE Hours are as per AAC Reduction Tables.

Airframe and Engine SOE Requirements for the holder of both the B737-600/700/800/900

and CFM-56 (B737-600/700/800/900) ratings

For an applicant who holds both B737-300/400 Airframe and CFM-56 (B737-300/400) Engine

ratings the minimum recommended SOE hours is 150 hours covering both categories, with

minimum hours in each ATA Chapter as set out in the following tables. The difference in hours

between the minimum required in the nominated ATA Chapters and the minimum required for

the both Categories can be made up by tasks in any applicable ATA Chapter provided the

minimum hours and emphasis in the nominated Chapters are met.

Airframe SOE Requirements for the holder of a B737-600/700/800/900 airframe rating

The Minimum recommended SOE hours is 120 hours with the minimum hours in each ATA

Chapter as set out in the following table.

Note 1: This recommendation takes into account previous experience and therefore supersedes

the normal SOE reductions set out in AAC 9-91, unless specified in the table.

Note 2: A minimum of 120 hours total is recommended due to the changes in system philosophy

by the increased use of computer control and monitoring, therefore the experience recorded

should include use of CDU and BITE to test/troubleshoot/confirm system operation.

Note 3: If the applicant also holds a rating for A320, B767, B747-400 or aircraft with similar

technology - SOE requirements can be reduced to minimum hours for each ATA Chapter listed

below.

Note 4: Experience required in ATA Chapter 21 – Airconditioning: Nil hours if trained and

experienced on both -300 and -400 airconditioning systems; or 15 hours if trained and

experience on –300 only with an emphasis on -400/800/900 zone temp control system and water

separator system. This experience may be gained on –400 aircraft.

Note 5: If applicant’s experience is on BBJ - Add 5 hours for BBJ auxiliary fuel tank system.

Note 6: The difference in hours between the minimum required in the nominated ATA Chapters

and the minimum required for the Airframe Category can be made up by tasks in any applicable

ATA Chapter provided the minimum hours and emphasis in the nominated Chapters are met.

Engine SOE Requirements for CFM-56 (B737-600/700/800/900)

For an applicant who holds CFM-56 (B737-300/400) Engine rating the minimum recommended

Note 3: If the applicant also holds an engine rating for A320, B767, B747-400 or aircraft with

similar technology - SOE requirements can be reduced to minimum hours for each ATA

Chapter listed.






Note 4: The lesser of 25 hours or as per AAC 9-92.

Note 5: Emphasis should be on: engine installation; fan maintenance; engine ground running;

operational/functional testing; and troubleshooting.

Note 6: The difference in hours between the minimum required in the nominated ATA Chapters

and the minimum required for the Engine Category can be made up by tasks in any applicable

ATA Chapter provided the minimum hours and emphasis in the nominated Chapters are met.

Note 1: The above table represents the general reductions that may be claimed by applicants

applying for piston or gas turbine engine ratings. This table is not designed to account for the

“ifs, buts and what abouts”. If a person believes that they should have a different reduction to

that normally available via the table, then the person must refer to paragraph 3.10 of the

Schedule of Experience and make representation accordingly.

Note 2: Paragraph 3.10 of the Schedule of Experience provides for SOE reduction if an

applicant believes that the hours for a particular ATA chapter represents an onerous task.

Onerous tasks include those that cannot be easily satisfied due to inherent reliability of

systems and equipment; and those that the applicant believe they have already satisfied via

experience on systems and equipment which are closely allied to those being applied for. A

claim for a reduced experience requirement (beyond that provided by Table 3) may also be

based on the evidence provided by previously submitted SOE. Any application for a reduction

in SOE requirements should be submitted as soon as possible after obtaining the SOE.

Note 3: Where an engine is of the same basic type but installed in different aircraft, they will

be treated as one (1) rating for the purposes of the Rating Reduction Table 3.

Note 4: The holder of an Engine licence rated Groups 1 and 3 who applies for a Group 21

Piston Engine rating may be granted a 20% reduction from the hours required in Table 2. This

reduction is in addition to the reduction specified in this table to a maximum of 75%.

Note 5: The Maximum reduction in SOE base hours is 75% unless specifically stated.

Acceptance of Experience for Engine Rating Gained on Another Aircraft Type

Group 21 or Group 22 specific engine type ratings allow a LAME to be part of the airworthiness

control system for an engine and the associated systems in an aircraft, not just the bare engine.

Therefore, CASA needs to be satisfied that the applicant has adequate experience with the

layout, location, operation and other aspects of maintaining the engine in the related aircraft type

prior to granting a rating. Some of these ratings only apply to a particular aircraft type, e.g. RR

GE CF34-3(CL601/604)

However, CASA recognises that many tasks are identical on an engine type irrespective of the

airframe in which a particular engine is installed, therefore some experience gained on one

installation is acceptable towards a rating for the same engine in another installation.

The following table provides guidance to minimum experience in each ATA Chapter in the SOE

that must be gained by performing maintenance on the engine type installed in correct airframe.

“Correct” in this context means the airframe identified in the rating applied for. Other

experience may be accepted when gained on the engine type installed in another aircraft

type/model from the same manufacturer. Experience gained on the engine type installed in an

airframe for another manufacturer will need to be assessed on a case-by-case basis following a

request from an applicant.

These minimum hours are applicable after the normal reductions (As per AAC 9-92) on the basis

of ratings already held are applied. These minimum hours may be further reduced if the

applicant holds a rating for an engine in the airframe to which the application applies.

The maintenance performed on the correct aircraft must include the areas of emphasis shown in

the table.

Identical Tasks. Identical tasks are those that involve the same parts, tools, processes and skills

as the same task on the same engine type in another airframe type. As an example the removal

and replacement of an oil filter would be identical although access may be by opening as access

panel on one aircraft and opening the cowls on another. However, a functional test of the

ignition system would not be identical since the controls, circuit breakers and procedures will

differ in some ways between the different aircraft. Similarly, the removal and installation of an

oil filter locked by lockwire can be considered identical to that locked by a splitpin, however,

dry motoring the engine to check for leaks is not identical.

The applicant is responsible to demonstrate that tasks are identical and clearly identify all tasks

performed on another aircraft type in the SOE. If tasks are not demonstrated to be identical or

are not clearly identified as performed on another aircraft type – the tasks and SOE may be

rejected.

“Considerations” are aspects that may require consideration of possible variation of these

reductions due to installation features. These are not exhaustive; other factors may also need to

be considered.

Reductions may be granted on the basis of the AAC Part 9-92, however the minimum hours/

proportion on the correct type must be met.

Where one installation uses a hydromechanical control system and another full authority digital

engine controls (FADEC), all experience/tasks related to the control/monitoring/indication

aspects of the systems must be on the correct installation.

Where one installation has an MCDU or similar system used for maintenance purposes, all

experience related to functional/operational testing and troubleshooting aspects must be on the

correct installation.

# Denotes the examinations to be passed for Group 21 or Group 22 as applicable.

Note 1: A separate Specific Type (GS) examination is required for each additional rating in

Group 21 or Group 22.

Note 2: The written examination GS will only be available for Group 21 and 22 engines which

are not fitted to high capacity aircraft, should a mandatory training course, acceptable to the

Authority, as required in CAO 100.92 para 5.2 not be available.

Note 3: Where an engine in Group 21 or Group 22 is considered by the Authority to be

sufficiently similar to an engine for which a rating is held, GS becomes GO for the installation

and engine/airframe system differences.






Note 4: Applicants who hold a credit for examinations IA, IZ and EB will be granted a credit

for examination BC.

Note 5: A credit for examination QB may be granted to a person who holds credits for

examinations BA, BB and BC provided the credits for these examinations were obtained from

the full format examinations sat and passed after 1 January 1989.

Note 6: The specific type examination GS for gas turbine propulsion engines installed in

aircraft also fitted with either an Airesearch GTCP36- 300, GTCP- 331, GTCP-660 and

TSCP-700 series or a P&W (C) PW901A Auxiliary Power Unit will be supplemented with an

additional Part 3 examination covering the particular APU.

Note 7: A specific type oral examination GO is also required for each rating in Group 21 and

22 where the practical experience for that rating is gained within an approved Practical

Consolidation Training (PCT) Program.

Mandatory Training Courses - Groups 21 and 22

As specified in paragraph 5.2 of CAO Section 100.92 Issue 3 all applicants for engine ratings

classified Groups 21 and 22 and listed in Tables 1 and 2 of sub- section 4 of this AAC, are

required to have successfully completed a relevant training course acceptable to the Authority as

a prerequisite to gaining the rating.

For a variety of reasons courses and associated examinations may not be available to personnel

who are trying to gain a type course examination credit. CASA no longer allocates resources to

the maintenance, update or delivery of Group 21 and 22 Specific Type Examinations. Aircraft

type training is an activity that CASA believes should be commercially delivered.

Situations may arise where AME are unable to access type course training and associated

examination credit. AME so affected are encouraged to contact CASA so that the individual’s

particular circumstances can be reviewed.

7. Engine Ground Run Training

Guidelines for the development and conduct of engine ground run training are contained in AAC
