"Did anyone else know about the EASA thing here?"
No! Which makes the CAA case even more absurd.
Good Vibs - As to the situation in Germany, are you flying Commercial Air Transport (Public Transport with passengers) after age 60 or Aerial Work? Do you have that same distinction there?
Sorry, I don't want any thread drift about CAT/Aerial work here, but it may explain why the CAA thought they had a case?
