I just got the following in an email mailshot from the USA
The FSDO responsible for Europe is either the NY IFU, or the Frankfurt one.
Has anybody ever heard of anybody managing to get a ferry permit (as described above i.e. aircraft not airworthy) in Europe?
A ferry Permit is a sub-ICAO document, and so only automatically useable in US airspace.
So, to fly in Europe, you’d also need individual overflight permissions from the nation owning each FIR you intend to fly through.
I have some experience of this ferrying out of CofA G-reg aeroplanes on a permit issued for ferry purposes, and can see no reason why the regs should treat a US aircraft more leniently.
