so which aircraft reg does
However, EASA has advised that such validations should give the same privileges as an EASA licence, so that the licence holder should be entitled to fly an aircraft registered anywhere
apply to?
It applies to all aircraft registered anywhere. But, the key point is that "validation" is a one-time process, valid for 12months and still requires some exam passes and a skills test. It is of little practical value except for someone who absolutely needs the extra time to get the EASA licences.
