There are two types of Aircraft Maintenance Licenses currently recognized by the Irish Aviation Authority.

  1. Aircraft Maintenance Licences (AML,s) , commonly referred to as a Part 66 Licence.
  2. Aircraft Maintenance Engineers' Licences (AMEL), commonly referred to as a National Licence.

Aircraft Maintenance Licenses (AML,s)

are issued in accordance with the requirements of Commission Regulation (EC) No 1321/2014 Annex III (Part-66) for aircraft that are subject to European regulation (EU) 2018/1139. This is the Part 66 licence that is normally issued.  

Holders of UK issued Part-66 licences seeking to transfer to an Irish Licence should expect extended processing times in advance of expected Brexit date.

Applicants should familiarise themselves with the submission deadlines published by the UK CAA here 

Applicants should note that applications that have not completed prior to Brexit may no longer be valid within the EU. Please refer to the guidance documentation issued by the EU Commission here

Applications received after 4 September 2020 may not be considered for processing.

Aircraft Maintenance Engineers' Licenses (AMEL)

are issued in accordance with the Irish Aviation Authority (Personnel Licensing Order) SI 333 of 2000. These licences are referred to as national licences. With effect from 28th September 2010 the privileges of a national licence may only be used for the certification of maintenance performed on aircraft which are not subject to (EU) 2018/1139. Irish registered aircraft which are not subject to European regulation (EU) 2018/1139 may have maintenance certified by persons holding the appropriate rating on their national Aircraft Maintenance Engineer's Licences (AMEL) in accordance with the privileges stated in Irish Aviation Authority (Personnel Licensing Order) SI 333 of 2000.
