5. the name and address of the registered operator of the aircraft;

Aircraft utilisation limitations affecting the validity of the program (c) If applicable, any limitations in terms of aircraft’s utilisations that affect the validity of the

maintenance program or part of the program must be set out in the program. Example of such limitations are annual aircraft flying hour or number of flights, the average duration of flight and the maximum altitude for the flight.

(d) If the specified utilisation limitations are exceeded, the maintenance program must be reviewed to make necessary changes to maintenance tasks and frequencies.

Information about each maintenance tasks (e) The maintenance program must set out details of all routine maintenance tasks to be carried out

on the aircraft and aeronautical products including following information for each task:

1. the description of the maintenance task;

2. the frequency of the maintenance task;

1. routine maintenance requirements included in the instruction for continuing airworthiness that are applicable to the aircraft and aeronautical product fitted to the aircraft with the exception mentioned in paragraph (j); and

Consultation Draft – CASR Part 42 MOS Page 2 of 39

2. routine maintenance requirement included in airworthiness directives applicable to the aircraft and aeronautical product fitted to the aircraft in accordance with CASR Part 39; and

3. any maintenance required by the responsible person for the aircraft; and

4. if the aircraft is subject to any of the following approvals or authorisations issued by CASA – the routine maintenance required under the approval or the authorisation:

(i) EDTO approval;

(ii) RVSM operational approval;

(iii) Navigation authorisation issued under CASR Subpart 91.U. (g) The maintenance program is considered to comply with a particular maintenance requirement

mentioned in paragraph (f) if the maintenance program: 1. includes the maintenance requirement;

2. does not reduce the scope or extent of the maintenance requirement;

3. does not vary the method or the technique if the maintenance requirement specifies a particular maintenance method or technique; and

4. does not make the interval less restrictive. Maintenance required by the responsible person (h) The responsible person must include in the maintenance program any maintenance that is

essential for continuing airworthiness and safe operation of the aircraft not included under the requirements mentioned in paragraph (f).

Non-compliance with routine maintenance requirements included in instruction for continuing airworthiness (i) CASR Part 42 requires that a proposed maintenance program or changes to a maintenance

program that does not comply with routine maintenance requirements included in the instruction for continuing airworthiness be approved by CASA under CASR Subpart 42.J.

(j) CASA may approve a proposed maintenance program or changes to the maintenance program that does not comply with a particular maintenance requirement included in the instruction for continuing airworthiness if: 1. the maintenance program provides another means for complying with the maintenance

requirement; or

2. no-compliance to the maintenance requirement is justified by the data derived from an approved reliability program for the aircraft; or

3. CASA is satisfied that non compliance to the maintenance requirement will have no adverse effect on the continuing airworthiness of the aircraft.

Information related to service life limited parts (k) The maintenance program must include a list of service life limited parts fitted to the aircraft

that includes the following information for each part: 1. description of the part;

2. location of the part on the aircraft;

3. the appropriate interval for removal of the part. One off extension to maintenance task interval (l) If the instructions for continuing airworthiness provide for a one off extension to the interval

for a maintenance task included in the instruction for continuing airworthiness, the


maintenance program may incorporate provision for a one off extension to the task interval in accordance with instruction for continuing airworthiness.

(m) If the instruction for continuing airworthiness does not provide for a one off extension to the interval for a maintenance task included in the instruction for continuing airworthiness, the maintenance program may incorporate provision for a one off extension to the task interval in accordance with the following criteria: 1. for a task controlled by calendar time – maximum variation of 10% of the interval or 1

month whichever is lesser; and

2. for a task not controlled by calendar time – maximum variation of 5% of the interval;

3. for a task controlled by more than one parameter – the more restrictive limit applicable in accordance with sub paragraphs 1. and/or 2.

(n) A one off extension to the maintenance task interval for an aircraft and aeronautical product is not permitted under this Section for the following maintenance: 1. maintenance that has been specified mandatory in the design approval for the aircraft and

aeronautical product such as airworthiness limitation, or certification maintenance requirement;

2. maintenance required by an airworthiness directive; and

3. replacement of service life limited parts. (o) Any extension to the maintenance task interval made this section must not be cumulative. For

example if a maintenance task having an interval of 1000 hours was carried at 1050 hours; next time the maintenance must be carried no later than 950 hours from the previous maintenance.


CASR Part 42 MOS Chapter B Requirements for an approved Reliability Program CASR 42.025 (2) (b) (a) General

(i) The reliability program must be in documented in writing. (ii) The program must clearly define the significant terms used in the program. Common

terms used throughout the industry need not be defined as long as the same meaning is intended.

(iii) The type, model and registration marks of the aircraft controlled by the program must be included in the program.

(b) Program elements (i) A reliability program document must describe at least the following basic elements:

1. objective of the program; 2. program application; 3. administration of the program; 4. procedures for establishing and reviewing performance 5. standards 6. data collection system; 7. methods for analysis and interpretation of data; 8. display of information; 9. corrective action; 10. program evaluation and review 11. pooling arrangement.

(c) Objective of the program (i) The objective of the reliability program must be described in the program.

(ii) The applicable instruction for continuing airworthiness must be followed to establish the objective of the program.

(iii) As a minimum the reliability program must provide a means to ensuring maintenance program task are effective and their periodicity is adequate for continuing airworthiness of the aircraft.

(d) Program application (i) The aircraft parts, aircraft systems, aircraft structural elements and maintenance

program tasks controlled by the reliability program must be clearly defined. (i) Where some items such as aircraft structure, engines, and auxiliary power units are

controlled by a separate program, such as manufacturer structural sampling or life development program this must be referenced in the reliability program.

(e) Administration of the program (i) The chains of responsibility for the administration of the program must be defined

clearly. (ii) Authority delegated to individuals or organisational elements for the enforcement of

policy and to corrective actions must be adequately described. (f) Establishing and reviewing performance standards (alert level)

(i) Each program must include an initial performance standard that defines the acceptable reliability for each item controlled by the program.


(ii) Various methods may be used to evaluate and control performance such as premature removal rates, in-flight shutdown rates, confirmed failure rates, flight delays, cancellation rates or internal leakage rates.

(iii) In some cases upper and lower limits may be established. This represents a reliability band or range and provides the standard by which the operator intends to interpret the reliability. The corrective action or follow up requirements for each limit must be fully explained in the program.

(iv) In other cases, target numbers may be set to specify aircraft system or component reliability performance levels which the operator expects to achieve.

(v) Alert levels must, where possible, be based on the number of events, which have occurred during a representative period of safe operation of the aircraft fleet. They need to be up-dated periodically to reflect operating experience, product improvement and changes in procedures.

(vi) When establishing alert levels based on operating experience, the normal period of operation taken is between two and three years dependent on fleet size and utilisation. The alert levels should usually be so calculated as to be appropriate to events recorded in one monthly or three-monthly periods of operation. Large fleets will generate sufficient information much sooner than small fleets.

(vii) Where there is insufficient operating experience, or when a program for a new aircraft type is being established, the following approach may be used: 1. For a new aircraft type, during the first two years of operation, alert levels may be

established in conjunction with the aircraft type certificate holder’s and operator’s experience and must be closely monitored for effectiveness during the induction period. Program data should still be accumulated for future use.

2. For an established aircraft type with a new operator, the experience of other operators may be utilised until the new operator has accumulated a sufficient period of own experience. Alternatively, experience gained from operation of a similar aircraft model may be used.

3. While setting alert levels for the latest aircraft designs, computed values based on the degree of system and component in-service expected reliability assumed in the design of the aircraft may also be used. These initial predictions must be replaced when sufficient in-service experience has been accumulated.

(i) The program must contain procedures for monitoring and reviewing alert level at regular interval based on the operating experience.

(ii) The alert level must be responsive and sensitive to the level of reliability experienced. It should not be so high that even abnormal variations would not cause an alert, or so low that it is constantly exceeded in spite of the corrective action measures.

(iii) If during the period between re-calculation of an alert level a significant change in the reliability of an item is experienced, which relates to the introduction of a known action such as modification, changes to maintenance or operating procedures, then the alert level applicable to the item should be re-assessed and revised on the data subsequent to the change.

(iv) Procedures for changes in alert levels should be outlined in the reliability program. (g) Data collection system

(i) A description of the data collection system relating to the items controlled by the program must be included in the program. The following must be adequately covered: 1. flow of information. 2. identification of sources of information. 3. description of steps of data development from source to analysis.


4. organizational responsibilities for each step of data development. (ii) The data collected:

1. must be accurate and factual to support a high degree of confidence in any derived conclusion;

2. must be obtained from units functioning under operational conditions;

3. must be directly related to the established levels of performance; (iii) Typical source of data are:

1. pilot reports;

2. unscheduled removals;

3. confirmed failures;

4. sampling inspections;

5. shop findings;

6. functional checks;

7. bench checks; (iv) All of the above sources may not necessarily be covered in each and every program.

The scope and objective of the program and items controlled by the program will dictate the nature and source of data.

(v) Samples of data to be collected must be included in the program document. This includes engine disassembly and inspection reports, part condition reports, mechanical delay and cancellation reports, flight log reports, engine shutdown reports etc.

(h) Analysis and interpretation of data (i) The method employed for examining, analysing and interpreting the data generated by

the program should be explained. (ii) Methods must be varied according to the content and quantity of information of

individual program. (iii) The methods must enable the performance of the items controlled by the program to be

measured. They must facilitate recognition, diagnosis and recording of significant problems. Such a process may involve: 1. comparisons of operational reliability with established standards;

2. analysis and interpretation of trends;

3. the evaluation of repetitive defects;

4. confidence testing of expected and achieved results;

5. studies of life-bands and survival characteristics;

6. reliability predictions;

7. other methods of assessment. (i) Display of information

(i) The format display must be such that allows easy identification of trends, events and any specific highlights.

(ii) Collected information may be displayed graphically or in a tabular format or a combination of both.

(iii) The rules governing any separation or discarding of information prior to incorporation into these formats must be stated.


(iv) The display of information should include provisions for ‘nil returns’ to aid the examination of the total information.

(v) Where ‘performance standards’ or ‘alert levels’ are included in the program, the display of information must be oriented accordingly.

(j) Corrective actions (i) The procedures for implementing corrective actions and for monitoring the

effectiveness of the corrective actions should be fully described. (ii) Corrective actions must correct any reduction in reliability revealed by the program and

could take the form of: 1. changes to maintenance, operational procedures or techniques; 2. changes to maintenance program tasks including escalation or de-escalation of

tasks, addition, modification or deletion of tasks; 3. one time special maintenance for the fleet; 4. initiation of modifications to aircraft and aeronautical products; 5. changes to provisioning of spare parts for maintenance; 6. changes to manpower and equipment planning for maintenance; 7. training of maintenance personnel.

(iii) The corrective action must include a planned completion date for each corrective action, where applicable.

(iv) The procedures must include notification to the individual or the organisational element responsible for taking the corrective action.

(v) The procedures must include provision of periodic feedback until such time as performance has reached an acceptable level.

(k) Program evaluation and review (i) The program should describe the procedures for continuous monitoring of the

effectiveness of the program and identify the individuals or organisational elements responsibilities regarding this.

(ii) The program must contain procedures for implementing changes to the program and identify the individuals or the organisational element responsible for the proposing and preparing of changes to the program.

(iii) Program must provide for a periodic review to determine that established performance standards is still realistic.

(iv) The time periods and the procedures for both routine and non-routine reviews of maintenance control should be detailed.

(l) Pooling arrangement (i) For small fleet, in order that sufficient data may be analysed it is permitted to ‘pool’

data that is to collate data from a number of operators the same type of aircraft. (ii) For the purpose of this Section, a small fleet of aircraft is a fleet of less than 6 aircraft

of the same type. (iii) For the analysis to be valid, the aircraft configuration, the mode of operation, and

maintenance program as procedures must be substantially the same. Following list gives guidance on the primary factors which need to be taken into account. 1. certification factors such as:

1.1.1. compliance with TCDS; 1.1.2. modification status; 1.1.3. compliance with service bulletins (SB);

2. operational factors such as:


1.1.1. operational environment; 1.1.2. operational rules; 1.1.3. utilisation rate and type; 1.1.4. operational approval such as EDTO, RVSM; 1.1.5. use of MEL

3. maintenance factors such as: 1.1.1. aircraft age; 1.1.2. maintenance program; 1.1.3. maintenance procedures; 1.1.4. maintenance standards;

(iv) Although not all of the above factors to be completely common, it is necessary that a substantial amount of commonality exists.

(v) In case of a short term lease agreement more flexibility may be granted by the CASA, so as to allow the aircraft to operate under the same program during the term of the lease.

(vi) It is acceptable for a CAMO or a RO to participate in a reliability program managed by the aircraft manufacturer, if the CASA is satisfied that the manufacturer’s reliability program complies with the intent of this Chapter.

42.A.Appendix II Organisation Approval Class and Rating System

1. Table 1 details the extent of CASR Subpart F approvals available to be granted to a single employee AMO. Table 2 details the full extent of approval possible for a CASR Subpart 42.F organisation in a standardised form. An organisation will may 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 or 2, a CASR Subpart 42.F organisation must describe the scope of work in its Exposition using the classes and ratings of the tables. Paragraph 10 details amendment requirements for the capability list.

3. Within the approval class(es) and rating(s) granted by CASA, the scope of work specified in a capability list in the organisation’s Exposition may further define the exact limits of approval. The Capabilities List must not specify work that falls outside of class(es) and rating(s) limitations specified on the Certificate.

4. A category A class rating means that the CASR Subpart 42.F organisation may carry out maintenance on the aircraft and any aeronautical product (including engines/APUs) only whilst such aeronautical products are fitted to the aircraft. An exception to this requirement is provided when aeronautical products can be temporarily removed for maintenance when such removal is expressly permitted by the Aircraft Maintenance Manual (AMM) to improve access for maintenance and subject to any procedures or limitations included in the AMM.

5. A category B class rating means that the CASR Subpart 42.F organisation may carry out maintenance on the uninstalled engine/APU (‘Auxiliary Power Unit’) and engine/APU aeronautical products, only whilst such aeronautical products are fitted to the engine/APU. An exception to this requirement is provided when such products can be temporarily removed for maintenance when such removal is expressly permitted by the engine/APU manual to improve access for maintenance and subject to any procedures or limitations included in the engine/APU manual.

6. A category C class rating means that the CASR Subpart 42.F organisation may carry out maintenance on uninstalled aeronautical products (excluding engines and APUs) intended for fitment to the aircraft or engine/APU. The limitation section of the Approval Certificate will specify the scope of such maintenance thereby indicating the extent of approval. A CASR Subpart 42.F organisation with a category C class rating may also carry out maintenance on installed aeronautical products during aircraft maintenance or at an engine/APU maintenance facility subject to a control procedure in the maintenance organisation’s Exposition. The Exposition’s scope of work will have to reflect such activity where permitted by CASA.

7. The D1 — Non-Destructive Testing (NDT) rating is only necessary for a CASR Subpart 42.F organisation that carries out NDT as a particular task for another organisation. A CASR Subpart 42.F organisation with a class rating in A, B or C category may carry out NDT on products it is maintaining subject to the maintenance organisation’s Exposition containing NDT procedures, without the need for a D1 class rating. A category D class rating is a self contained class rating not necessarily related to a specific aircraft, engine or other aeronautical product.

8. Table 2 specifies the types of limitation possible for an Approval Certificate. It is possible to tailor the maintenance scope statement to the specific activity carried by the organisation e.g. 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. Where Table 2 makes reference to series, type and group in the limitation section of class A and B:

(a) Series means a specific type series such as Cessna 150 or Cessna 172 or Beech 55 series or continental O-200 series etc.


(b) Type means a specific type or model such as Cessna 172RG type. Any number of series or types may be quoted.

(c) Group means for example Cessna single piston engined aircraft or Lycoming non-supercharged piston engines etc.

10. Organisational amendments to a capability list are possible subject to any amendment being carried out in accordance with a CASA approved control procedure as detailed in the organisations exposition. The procedure will have to 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 CASR Subpart42.F for products or services added to the list.

11. A CASR Subpart 42.F organisation that employs only one person to both plan and carry out all maintenance (single-person) can only hold a limited scope of approval rating as per Table 1.
