Now be fair Javelin. In the not too distant past PFA has approved the Ban-Bi, Eurostar, Icarus C42, 4-seat Jabiru, Europa - all under the same Chief Engineer that our man would have to write to. I still think he's little chance, and have been known to criticise the PFA myself, but what you're saying simply isn't true.
That article in PF actually said that none of those designs have yet been approved. Knowing FD reasonably well he's not known for taking prisoners amongst substandard aeroplanes, and certainly no great sympathy for overseas "approvals" and safety data that I know is often fictional - but equally I've never seen him block a genuinely good safe design.
There is a CAA policy about "if it can hold a CofA it must", but I know that PFA has been trying to erode that position and it may be that such an excuse to try and erode it further would be welcomed - without knowing more detail it's hard to tell.
Just for the record, I don't work for the PFA but I am a member and I do know most of their engineering staff on a professional level.
