This page provides guidance to applicants for the renewal of a UK Part 66 Aircraft Maintenance Licence (AML)


You are only able to apply to renew your Part 66 Aircraft Maintenance Licence 60 days prior to the expiry date.

Currently there is no experience requirement to renew your UK Part 66 aircraft maintenance licence.

In circumstances where you may be renewing at the same time as your British Civil Airworthiness Requirements (BCAR) Section L licence, you will be required to apply separately using the Application for Initial Issue, Amendment or Renewal of an Engineer Licence.

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.

How do I apply?

Once all of the requirements have been met, please complete:

  • SRG 1014 (if applying using a paper form)
  • Online application

    The application, supporting documents and original licence should be posted to:

    Civil Aviation Authority
    Aviation House
    Licensing Assessment Team
    Beehive Ring Road
    West Sussex
    RH6 0YR

What do I need to include with my application?

  • Application for Initial Issue, Amendment or Renewal of an Engineer Licence.
  • For existing licence holders your original Part 66 Aircraft Maintenance licence will need to be submitted with any application for amendment or renewal of an engineer's licence.
  • If applying for change of name and or nationality a true copy of the supporting document certified by your Quality Manager, for example, your valid passport/change of name deed poll/marriage certificate.

Please note the Civil Aviation Authority (CAA) has the right to request the return of the original Part 66 Aircraft Maintenance Licence at any point of your application.

How long is it valid for?

The UK Part 66 Aircraft Maintenance Licence is valid for 5 years from the date of issue


The fee is £410.00 for the renewal of an Aircraft Maintenance Licence.

If you are applying for any other additional services, the appropriate fee will also apply.

An additional fee will be payable if you wish your documents to be returned by secure courier.

Full details are available in the current Scheme of Charges (Personnel licensing).

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

The 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.

Close Costs

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.
