At the risk of seeming churlish Ghengis, what exactly has changed?
A whole list of aircraft, including Concorde, Nimrods, Hunters, Pups, B 206's, Cubs, Luscombes, Austers, Moths, Venoms, Sea Vixens etc etc are remaining subject to National Airworthiness requirements rather than coming under EASA. Given the impossibility of moving something currently on a Permit (be it a CAA Permit or a PFA one) back on to a C of A this was the only real option.
Many on the list are not eligible for a C of A and so couldn't come under EASA in any case. (I don't believe anyone at any time has suggested an EASA Permit to Fly.)
Article 9A is not changing so not a single aircraft will be added to the PFA fleet as a result.
Which is not to suggest that PFA Engineering is twiddling its thumbs.
