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 £173 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review, in respect of those applications that the CAA has rejected or where the applicant has withdrawn his/her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. 310, Personnel Licensing Scheme of Charges, para. 13.1 table 58 refs. a,
c, i, d and/or e. This action is in line with the CAA Charges Waiver and Refund Policy from 1 September 2016.
