According to the Part 145.1 EASA is the competent authority for organisations located outside the EU territories. Within the EU Member States each National Aviation Authority (NAA) is the competent authority.
In accordance with above specified regulatory paragraph, EASA publishes the list of valid and non-valid Foreign EASA Part-145 approvals located outside of the EU Member States which are issued by EASA.
Following the same reference each EU NAA is tasked to issue a similar list of approvals granted on its own territory. Unfortunately not all EU NAA do have such a list of national approvals or even a website.
For the moment we can provide you with the list of EASA member states on our website.
