To ensure you complete your application correctly, refer to the following associated rules, regulations and forms to support you with your application:

·         UK Regulation (EU) No 1321/2014

·         Scheme of Charges (Personnel licensing)

·         CAA Refund Policy

The Service Level Agreement (SLA) for initial Part-66 licences is 51 working days. This includes initial assessment by a Licensing Officer (15 working days), technical assessment of your on-the-job experience by a Surveyor (30 working days), plus 6 days for issue and dispatch of the licence.

You will receive automated email updates as your application progresses through the process. You can also track the progress of your application at any time by logging into your CAA Customer Portal account, selecting "Your Services" and then selecting the Aircraft Maintenance Licence Service. You may then click on "All Applications" for further information.

Where an application is placed on hold, the working days to process the application will be counted from the date of receipt of the requested additional information. Should the application be placed on hold by a surveyor, the new SLA for the application will be 30 working days.

For this reason, be diligent in reviewing the guidance on this site, within the application and the requirements of UK Part 66, before application. Missing information or certification will delay your application and may result in the application being rejected. A fee will be charged if the assessment results in the rejection of your application. This will also be applied if you choose to cancel your application

For a small number of applications, a Licensing Officer may require additional guidance which requires a referral to be made to a Technical Officer. The Technical Officer will review the case within five working days, however if further advice is needed this will be reviewed at a bi-weekly complex case review session. In such cases the application will take longer to process than our standard turnaround times.

If you are dissatisfied by the service provided to you by us or wish to raise a complaint regarding a member of staff, our complaints process is detailed on our dedicated complaints webpage.

The assessment of your application is completed by a Licensing Officer and Airworthiness 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. Following this period, the CAA may reject the application if no satisfactory response is received.

Should an application be unsuccessful, a rejection fee will be deducted from the application fee to cover the cost of the assessment carried out. The remainder may be refunded to the applicant.

Should you choose to cancel your application, a fee will apply.

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

You will need to Renew a UK Part 66 Aircraft Maintenance Licence.
