CAD Form 15a
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 MCAR-M. 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 MCAR-M. 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 CAD, the scope of work specified in the maintenance 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 maintenance organisation approved in accordance with MCAR-M Subpart F may carry out maintenance on the aircraft and any component (including engines and/or Auxiliary Power Units (APUs), in accordance with aircraft maintenance data or, if agreed by CAD, in accordance with component maintenance data, only whilst such components are fitted to the aircraft. Nevertheless, such A-rated approved maintenance organisation may temporarily remove a component for maintenance, in order to improve access to that component, except when such removal generates the need for additional maintenance not eligible for the provisions of this paragraph. This will be subject to a control procedure in the maintenance organisation exposition acceptable to CAD. The limitation section will specify the scope of such maintenance thereby indicating the extent of approval.
