FT - coincidentally I was browsing a back issue of Pilot mag last evening and there was a write up on an Ozzy Velocity.
In a sidebar there was a comment stating it was unlikely that the PFA would approve it as the designers were unable to supply the Association with stress calcs.
If I were really, realy, really super-serious about building one and no other aeroplane would EVER do, I'd:
a) contact the PFA to determine the veracity of para 2 above. If it was pukka
b) I'd arrange to have the stress calcs done by a suitably qualified person and I would submit those to the PFA. This is an expensive and tortuous path.
This may enable you to build a Velocity over here. But do be aware the PFA is VERY slow to turn these things around and I'd heed Ghengis' wise words in his earlier post:
"If it's not on the PFA list, or about to be (and take nobody's word on that except PFA Engineering), I'd not touch it - it will end in tears."
Stik - off to the workshop now for the next 8hrs!
