Actually I think you'll find EASA are going the other way as IO says - Aircraft registration not a problem, but EU resident must hold an EU licence to operate it.
Nope, still not right. My understanding is that if the OPERATOR is EU resident or established in the EU then the CREW must hold an EU licence or a foreign licence that has been rendered valid. The proposal is that this "rendering valid" will have a max duration of one year. No-one gives a monkey's what the nationality or residence of the pilot is and of course there is no requirement for the operator to hold any sort of licence (except perhaps an AOC).
Quite how you define "operator", "resident" and "established" is still a mystery and I suspect the lawyers are utterly clueless. Having been welcomed on board "This AAA Airways flight to ABC operated by BBB Airways on behalf of CCC Airways" it's clear to me that the whole thing resembles the entance to an old coaching inn, designed to allow the passage of a coach and horses.
Any N Reg is by definition US owned (typically by a trust). Quite how they propose to prevent that trust being the operator is something I don't quite follow.
Of course for an AOC flight they have no problem, the "operator" will be the holder of the AOC under which the flight is being operated.
