Mandatory Permit Directives are issued by the CAA if a serious issue arrises with the aircraft. They may be a simple instruction, such as not to fly the aircraft, but may cover the solution to the problem. In the cases where they do not offer a solution then this must be found in the appropriate factory SB or modifications.
