European Aviation Safety Agency
Organisations and personnel involved in the continuing airworthiness of aircraft and components, including maintenance, shall comply with the provisions of Part-M and where appropriate those specified in Part-145 and
Part-66.
As a consequence, Part-M applies also to Part-145 organisations, in particular the following paragraphs:
Subpart D: Maintenance standards (maintenance data, performance of maintenance, aircraft defects)
Subpart E: Components (installation, maintenance, life limited components, control of unserviceable components)
Slide 2

European Aviation Safety Agency
Organisations involved in the maintenance of large aircraft or of aircraft used in commercial air transport, and components intended for fitment thereto, shall be approved in accordance with the provisions of Annex II (Part-145).
Slide 3

European Aviation Safety Agency
Requirements for approval of an organisation for maintenance of aircraft and components
Including facilities outside Member State if
Identified in exposition
Control procedures in place
Authority satisfied that they are integral part of the organisation
Slide 4

European Aviation Safety Agency
A rating: maintenance of aircraft and components (according to aircraft maintenance data) while installed on the aircraft (or temporarily removed to facilitate access)
B rating: maintenance on engines/APU and components
(according to engine/APU maintenance data) while installed on the engine/APU (or temporarily removed to facilitate access)
C rating: maintenance on components other than engine/APU.
D1 rating: NDT. Only required when the Part-145 performs NDT for other organisations (issuance of Form 1). This is a rating not related to particular aircraft, engines or components.
NOTE: Refer to M.A.502 for more details.
Slide 5

European Aviation Safety Agency
Component certifying staff is only required for B and C rated organisations. When these organisations need to carry out NDT as part of component maintenance, the
NDT should be carried out by personnel qualified in accordance with 145.A.30 (f).
These NDT personnel do not need to be certifying staff.
The component maintenance, including the NDT, should be released by appropriate component certifying staff.
The need for NDT certifying staff qualified in accordance with 145.A.30 (f) and 145.A.35 is only required for D1 rated organisations.
