Thanks for all your replies.
Only 2 problems....
1) I'm in Holland, I have no access to a UK examiner. Nor will I have for a long time.
2) The expiry date of my SEP was on Monday. I had a Dutch examiner sign it on Monday. So now it's no longer valid then :-(
I only called the CAA to ask a question about the EASA conversion, then got slammed with this bureaucratic nonsense.
What do I do now then, knowing that my SEP has expired and that I incorrectly had an incorrect examiner sign it off?
