Hi CMN
Used aircraft into Europe / EASA
Just be reminded, that no EASA country accepts an aircraft with a Form 337, respectively a STC which is not validated by them, except this STC has been installed before Sep 28, 03 on the same type of aircraft, which was registered in an EU country before this date.
Source: EASA Regulation 1702/2003
Holders of STC (or equivalent), approvals of major changes, major repair design approvals or approvals of parts and appliances issued under national regulations by Member States prior to 28 September 2003 and grand-fathered in accordance with Regulation 1702/2003, article 2.13 and 2.14 do not need to demonstrate their capability, until the time they apply for a new STC, major repair design approval or ETSOA * under Part 21.
P.S What about this new jet, called Grob SPn, something around 7 M US$.
