3rd country aircraft, e.g. C172 and PA28, are still 'EASA aircraft', no matter which their state of registry.....
Interesting. How about a Globe Swift, Stinson 108, Commonwealth Skyranger, Luscombe 8A etc, with no EASA type certificate, but all operating on ICAO compliant standard category airworthiness certificates and as such legally usable (and used for) paid flight training and anything else the C172 or PA28 are used for?
