Refunds – rejected or withdrawn applications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 us due to, for example, lack of experience criteria. This has resulted in the us refunding 100% of the application charge paid even though our time has been incurred to review the application in order to reach the rejection decision.
We are required to recover its costs from those that have caused those costs to be incurred. Therefore, for applications received from 15 September 2016, we will deduct £218 to recover the average costs of its application review, in respect of those applications that we have rejected or where the applicant has withdrawn his/her application before we have completed its review.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.

How long will it take for my application to be processed?
Processing time
Our Service Level Agreement (SLA) for the initial assessment of all applications is 10 working days. Where the application requires assessment by a Surveyor, the SLA is 31 working days. This includes 20 working days for the technical assessment of the application, plus an additional day for issue and dispatch of the licence.
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 21 working days.
For this reason, please 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.
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.
Due to high application volumes, we are currently experiencing a backlog of applications to be processed, which is also impacting the response times for correspondence. Initial assessments of applications are currently taking 15 working days, with technical assessments completed within 50 working days
What happens next?
- 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.
