L&S
Yes, the CAA stopped certified aircraft from obtaining a PFA permit to fly a few years ago now... much to the disapproval of the PFA.
Aircraft already on the scheme will remain though. I believe that only the smaller Austers were allowed on and then only for 2 seats.
Where are you based? as you are very welcome to have a go in the T-cart. Its a very efficient plane that glides like crazy and will float the lenth of a runway unless the approach speed is well nailed. Couple this with a surprisingly sharp stall and you have an aircraft that demands full attention in the curcuit - much more than a Cub.
Try to make the Auster-Cub fly-in (whenever it is!). I'll probably bring the L4, but we can talk about meeting up for the T-Cart-Auster comparison - It would be interesting!
