I have been reading the PART FCL document. If we strictly hold on to this document, our exams should be fine (if we complete them before 30 march 2019).
(1) Applicants shall take the entire set of theoretical knowledge examinations for a specific licence or rating under the responsibility of one Member State.
- We would in fact have taken all the exams under the responsibility of one Member State.
(c) Validity period ... (too long to put it here)
But this validity period does not mention anything regarding a member state that was in EASA and now it's not (of course, as nobody could predict what is happening)
But, as usual, I expect that the NAAs will put more problems than solutions, and that they will make their own interpretation of the law.
