Thanks Nopax,
the aircraft has already the registration document of the CAA but I am not living in the UK. I am presently starting to organize the restoration in Germany. So it will be difficult keeping everything going via the UK CAA. I am thinking however to continue via the UK way but need to find out how far local JAR approved technicians and inspectors can overview the restoration.
The aircraft will not be EASA certified ( does it matter???).
I got another tip to proceed via the LAA (light aircraft association) in the UK. Same problem; they only have UK based approved technicians and inspectors.
Your tip to call the CAA will definitely be the next step. NO way I want to spend all the money and effort to start all over again.
Regards
