Please note that, in the event of the UK leaving the EU without a negotiated agreement, some CAA website content and application forms may continue to carry the EASA logo or reference the EU or EASA rather than the UK CAA in the short term. These will be updated in due course following the UK’s departure from the EU. In the meantime, the guidance provided and the application forms accessed via the CAA website portal will continue to be valid.

There have been a number of applications received from 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 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 £177 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costs of its application review, in respect of those applications that the CAA has rejected or where the applicant has withdrawn his/her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 No. 334,
Personnel Licensing Scheme of Charges, para. 13.1 table 61 refs. a, c i), d and/or e. This action is in line with the
CAA Charges Waiver and Refund Policy.
