This page provides information to UK Part 66 Aircraft Maintenance Licence holders wishing to add a category or sub-category to their existing licence.
Pre-Requisites
You must hold an existing UK Part 66 Aircraft Maintenance Licence and have met the relevant knowledge and experience requirements to extend to include another Category/Sub-Category.
The UK Civil Aviation Authority (CAA) reserves the right to ask any applicant to provide the original documents to support any application for the initial issue, renewal or change to a UK Part 66 licence.
When extending a UK Part 66 Aircraft Maintenance Licence you are required to complete the relevant modules applicable to the Category/Sub-Category you are applying for (for information on the modules/part modules you will need to email eldweb@caa.co.uk).
Please note the EU/EASA Certificates of Recognition (CofR) may continue to be acceptable for inclusion on an UK Part-66 licence dependant on the date of issue:
- Any EASA Certificate of Recognition issued by an EU Part 147 MTOA (with a Form 11 dated during the two-year saving legislation period) - will be acceptable in support of UK Part 66 Licence. The course start date cannot exceed more than three years at the time of applying for the type rating.
- Any EASA Certificate of recognition issued by an EU Part 147 MTOA dated after 01 January 2023 will not be acceptable in support of a UK Part 66 Licence.
The EU/EASA Organisation approval certificate valid at the time the course was completed along with the CofRs must be submitted to support applications.
You will be required to provide the necessary amount of practical aircraft maintenance experience on operating aircraft in compliance with UK AMC 66.A.30(e) in a form and manner acceptable to the UK CAA, appropriate to the additional Category/Sub-Category of licence applied for, signed off by the appropriate signatory.
An acceptable format for demonstration of experience can be any of the following:
- Aircraft Maintenance Engineers Logbook (CAP741)
- Type Rating Record of Experience (SRG1007)
- or any other format agreed with the UK CAA
The experience requirement will be reduced by 50% if you have completed an approved Part 147 basic training course relevant to the Category/Sub-Category applied for.
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.
Please note if you are applying for a change of name and/or nationality you will be required to supply evidence in support of your request, for example, change of name deed poll/marriage certificate/valid passport.

Applications and documents posted from outside the UK
When submitting applications or documentation via post/courier to the UK please ensure that you complete the import declaration on any package in the correct manner.
Please ensure that you enter the “Value” of the package content as zero/nil. Otherwise, this will generate import duties in the UK which will be re-charged to you.
While there is a fee for the Civil Aviation Authority (CAA) application process, this does not represent an importation value of the package content. Therefore, the application fee should not be stated on the import declaration form that a candidate completes when posting supporting documents to CAA UK.
Same day services
Same day, special and customised delivery charges are available at an additional cost. This service is on request, which should be made at the time of initial application. Documents are worked to a same day turnaround from receipt of customer request by 11:00 to completion of the processing of the application by 16:30 on the same working day. The customer will be able to collect the documents by 16:30 on the same day or the documents shall be sent by Royal Mail special delivery, where this is included in the service.
Refunds – rejected or withdrawn applications
There have been a number of applications received from Aircraft Maintenance Licence (AML) applicants applying for issue of an AML or for additional privileges to be added to an existing AML which have been rejected by the Civil Aviation Authority (CAA) due to, for example, lack of experience criteria. This has resulted in the CAA refunding 100% of the application charge paid even though CAA time has been incurred to review the application in order to reach the rejection decision.
The CAA is required to recover its costs from those that have caused those costs to be incurred. Therefore, for applications received from 15 September 2016, the CAA will deduct £218 to recover the average costs of its application review, in respect of those applications that the CAA has rejected or where the applicant has withdrawn his/her application before the CAA has completed its review.
This deduction is associated with applications in respect of AML activities under the UK Official Record Series 5 , Personnel Licensing Scheme of Charges. This action is in line with the CAA Charges Waiver and Refund Policy.
What happens next?
- The assessment of your application is completed by a Licensing Officer and technical standards surveyor.
- Following an acceptable assessment the Licence is then processed, signed and dispatched to the individual.
- We will contact you if we have any queries regarding your application and may keep your application pending for 30 working days awaiting any additional documentation to be submitted.
- A refund fee may be charged if the assessment results in the rejection of your application. This will also be applied if you choose to cancel your application.
