4 seat Jodels on a permit - ah the holy grail.
There are several being built from scratch or wrecks, that are on permits. This is ONE 4 seater on a permit - rebuilt from a wrecked Germany machine. This was the first 4 seat permit Jodel - the great PFA 'break through'.
There are I think 2 other 1050's on permits - but they are retricted to 2 seats........ (restored under the 'old' rules??).
As for importing any production machine with a C of A, in its home country (apart from homebuilts and they are a real problem directly with the PFA!!!), it cannot be put on a permit. The CAA stopped this process (which is what resulted in so many Jodels, Cubs etc coming into Britain in the first place) in the mid 90s.
So unless you build it yourself forget 4 seats on a permit - you cannot import.
If you really need 4 seats then its C of A, (or better still N reg) or I suppose possibly leave it on the F, G or whatever.
To say the rules are frustrating is something of an understatement!
