Dear Group, the problem was:
a.) is it possible to get an experimental airplane certified outside U.S. territory under FAA Regulations? (in this case we are talking about germany or austria ) The answer is NO. The FAA Filed office in germany explained to me, that it is their policy not to certify ANY experimental aircraft outside U.S. territory. Quote. b.) is it possible to fly an N-registered, experimental aircraft legally in germany ( after it gets certified on U.S. territory ) The answer is YES. The LBA ( german avaiation administration ) explained to me, they would give general permission to my K2 to enter their airspace and stay in germany. They just reminded me, that I have to take care about customs for the plane. And they restrict all experimental aircraft to Day-VFR . b.) is it possible to fly an N-registered, experimental aircraft legally in austria ( after it gets certified on U.S. territory ) The answer is YES. Austrocontrol explained to me, they will issue a "validation" of my N-Number for 1 year. Means: every year, I have to proove my annual, insurance etc. No big deal. I forgot to ask about restrictions for operation ( VFR, Day + Nite, etc ). Sorry. There is also a good chance after flying some hours in Austria, to get the plane certified under OE-Registration - because it has prooven to fly safely. Summary: The only way to certify an experimental aircraft under FAA regulations is to get it certified in the U.S.A. Thereafter, it can be flown with some restrictions in germany and austria, and probably be converted to a OE-Registration but most likely not to a german D-registration. But you can fly in germany with a OE-Registration anyway. So austria is choice #1 . Anyone with contrary informations: your advice is very welcome. Best regards Ralf Simon
