The current process for dealing with an incomplete application for the issue of a licence or rating allows up to 30 days for a customer to comply before an application is cancelled.
From 4 February 2013 they will simply return it without discussion. The notice doesn't say whether the "assessment fee" which currently stands at £108 will be still be payable.
The benefit of this change is to streamline our processes, reduce costs and turnaround times
In the event of a mistake by the CAA I'd be interested to know whether they would refund the additional costs they incurred by sending the documentation back to the applicant rather than simply asking for additional information.
