Part 42 Exposition - MAAT information

The CASR Part 42 template in MAAT offers an exposition which contains guidance material and sample text to assist Organisations applying for a continuing airworthiness management organisation (CAMO) approval.

The sample text provided is suitable for a potential small or medium size CAMO with a simple organisational structure that would be responsible for managing continuing airworthiness for aircraft authorised to operate under its own Air Operator’s certificate (AOC). The content of the sample text relates directly to the requirements of Part 42 and the Part 42 Manual of Standards (MOS) as applicable to a CAMO. It will also serve as a useful starting point for those who have more complex operations.

It is important for the users of this template to appreciate that the sample text provided will not cater for the needs of all organisations of varying size and complexity or reflect the organisational structures, processes and procedures of a number of different organisations. It is for guidance only and the structure and content of a CAMOs exposition should reflect the unique structures, process and procedures of the CAMO. The content of each section and sub section should be expanded according to the complexity of the processes and procedures of the CAMO.

The sample text provided includes mandatory regulatory requirements and may also include text to illustrate an example of how a requirement may be described. The text can be amended with details of your specific process or, the provided process can be adopted.

Where the content of the exposition requires processes and procedures to be provided, these may be included in other documents provided they are referred to in the exposition. However, in that case, the other documents form part of the exposition and are subject to the same requirements and controls as the exposition. Processes and procedures included or referred to in the exposition should be of adequate depth and include enough details to demonstrate they establish compliance with the applicable requirements of Part 42 and the Part 42 MOS.

Duties and responsibilities of individuals as mentioned in the exposition should relate to the obligation of the organisation or the individual under Part 42 and Part 42 MOS, and are not meant to cover employment conditions, performance criteria or administrative functions. Where content of the exposition requires identifying the individual responsible for an action or a decision that is part of a process, it is intended that the individual will be identified by their position title (such as ‘continuing airworthiness manager’) or if applicable, by means that describes their function (such as ‘airworthiness review employees’ or ‘data entry clerks’).

Where content of the exposition deals with records to be created or kept by the organisation, the relevant procedures in the exposition should take into account the requirements of Subpart 42.N in relation to the following:

  • legibility of the record
  • retrieval of records
  • protection of the records from loss, damage or accidental alteration.

CASA recommends worksheets, checklists, forms, lists of items and personnel etc. required under the exposition or associated with the processes or procedures required by the exposition should be included as appendices at the end of the exposition. However, as mentioned above, they may be included in other documents that contain the processes and procedures or in any other document if it is convenient for the organisation to do so.
