Apply to Remove Limitations from the Basic Category of an EASA Part 66 Licence

How to make an application


An amended EASA Part 66 Aircraft Maintenance Licence is issued following the removal of all exclusions (National or EASA) to the relevant basic Category/Sub-Category that affects the certification privileges of the Licence holder.

Who can apply

You must hold an existing Part 66 aircraft maintenance Licence and have met the full requirements of the UK conversion basic examination standards, and the appropriate experience requirement.

You must have met the requirements in accordance with 66.A.45 (g) 2.  


If your experience has been gained in an EASA 145 Maintenance Organisation but an overseas company, original logbooks/worksheets and examination certificates will be required.

If your experience has been gained outside an EASA 145 Maintenance Organisation then you will be unable to proceed with your application at this present time. If you require more information or guidance on what to do next please email

The Part 66 Licence is not a progressive Licence and therefore applications received for the removal of limitations from a Category/Sub- Category must have met the requirements to remove all the limitations endorsed on their Licence as you are unable to lift limitations singularly. 
  • You must complete the relevant modules applicable to the limitations on the Basic Category/Sub-Category,  
    for information on the modules required you will need to email

  • Part modules can be completed within an organisation appropriately approved to conduct the UK CAA conversion exams.
    If the examinations are being conducted within a Part 147 organisation not approved by the UK CAA you will be required to sit full modules.  We cannot consider part modules.

  • You will be required to demonstrate a minimum of 6 months relevant practical maintenance experience appropriate to the limitations you are removing from the Category/Sub-Category, this can be demonstrated in the form of a logbook and / or worksheets ensuring the tasks have been signed off by the appropriate signatory.

  • The recommendation document will need to be completed by a Quality Manager or the immediate senior person within the Quality Department of your current employer, or the organisation where the experience is gained.

    NB: If you are applying for a change of name and or nationality you will be required to supply evidence in support of your request, e.g change of name deed poll/marriage certificate/valid passport.
