EASA Part-145 Approved Maintenance Organisations

In order to be able to carry out maintenance on aircraft, which are operated under the influence and control of EASA, organizations within that area of influence must apply to the relevant competent authority for approval to maintain aircraft, their components and to issue certificates of release to service in accordance with Part-145.

If the organization or organizations have their principal place or places of business within the borders of a Member State then that state will designate the authority.

If the organization or organizations have their principal place or places of business outside the borders of the Member States then the European Aviation Safety Agency (EASA) will be the relevant competent authority.

Organizations Approval Class and Rating System

•       An organization must be granted an approval ranging from a single class and rating with limitations to all classes and ratings with limitations.

•   the Part-145 approved maintenance organization is required to indicate scope of work in the maintenance organization exposition.

•  Within the approval class (as) and rating(s) granted by the Member State, the scope of work specified in the maintenance organization exposition defines the exact limits of approval. It is therefore essential that the approval class (as) and rating(s) and the organization’s scope of work are compatible.
