Appendix I
Organisations approval class and ratings system
1 Except for small AMOs referred to in clause 2, Table 1 outlines the full extent of approval possible under Part 145 in a standardised form. An AMO may be granted an approval ranging from a single class and rating with limitations to multiple classes and ratings with limitations. The approval class, rating and limitations sections of a Certificate of Approval issued by CASA specify the scope of maintenance approved for a Part 145 AMO to provide maintenance services for aircraft, aeronautical products or specialist maintenance.
2 A Part 145 AMO that employs only 1 person to both plan and carry out all maintenance can only hold a limited scope of approval ratings. The maximum permissible limits are as shown in Table 2.
3 In addition to the ratings and limitations listed on the certificate, the organisation is required by this MOS subparagraph 145.A.70 (a) 10 to set out the scope of the approval in its exposition, showing particularly the locations at which the AMO conducts maintenance as specified on the certificate of approval. This statement of capability must conform to, and not exceed the rating limitations specified on, the Certificate of Approval.
4 In addition to the statement of capability required under clause 3 above, an AMO may have a capability list and management procedure as part of its procedures under subparagraph 145.A.70 (a) 13 to manage a detailed capability list. The scope of work specified in the capability list further defines the exact limits of approval. The capability list must not specify work that falls outside of class and rating limitations specified on the Certificate of Approval. When a capability list is used, amendment will be in accordance with a procedure approved by CASA in the AMO’s 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 Part 145 for products or services added to the list.
5 The category A rating means that a Part 145 AMO may carry out aircraft maintenance as specified in accordance with maintenance data for the aircraft. An A rating also permits the AMO to provide maintenance services for specialist maintenance that is covered by the category A rating. Category A class ratings are subdivided into base or line maintenance and the AMO may be approved for either base or line maintenance or both.
6 The category B rating means that the Part 145 AMO may provide maintenance services that involve carrying out maintenance on an aeronautical product that is an engine or an Auxiliary Power Unit (APU), in accordance with maintenance data for the engine and the APU. A B rating also permits the AMO to provide maintenance services for specialist maintenance that is covered by the category B rating.
7 The category C rating means that the Part 145 AMO may provide maintenance services that involve carrying out maintenance on an aeronautical product other than an engine and an APU, in accordance with the maintenance data for the aeronautical product. A category C rating also permits the AMO to provide maintenance services for specialist maintenance that is covered by the category C rating.
8 The category D rating means that the Part 145 AMO may provide maintenance services for specialist maintenance on an aircraft or an aeronautical product without holding a category A rating for aircraft maintenance or a category B or C rating for aeronautical product maintenance.
9 Carrying out maintenance on an aircraft and carrying out maintenance on an aeronautical product have the meanings given by Part 3 of the CASR 1998 Dictionary.
10 The limitations section of the approval certificate is intended to give CASA maximum flexibility to customise the approval to a particular AMO. The limitations section of Table 1 describes the possible forms of limitations that CASA may apply to each rating to customise the approval for a particular AMO. In some cases, CASA may limit an organisation’s approval rating to particular types of maintenance. For example, a rating A may be limited to avionic systems maintenance only or a rating B1 may be limited to maintenance other than complete overhaul of the engine.
10 Where the limitations sections in Table 1 and Table 2 make reference to series, model and group for A and B ratings, they have the following meaning:
(a) series means a series of models with similar design covered by a single type certificate such as Boeing 737 series aircraft which include B737-300, 400, 500, 600, 700, 800 and 900 etc. or GE CF6-80 engines which include all CF6‑80A and CF6-80C2 models etc.
(b) model means a specific model of aircraft or engine as designated in the type certificate such as Airbus A320-231 aircraft or IAE V2500-A1 engine.
(c) group means group of aircraft or engines from the same manufacturer or having similar configuration and technology. Examples of groups are Cessna single piston engine aircraft or Lycoming non-supercharged piston engines etc.
For an A1 category rating, the limitation may specify an aircraft by series or model; or both the aircraft and engine by series or model, for example, A320 Series/IAE V2500 or B747-400 Series/RB211-524G2.
Note An AMO may be further limited by CASA in the scope of approval dependent upon the capability of the particular organisation.
