I am asking this to help a friend.
This used to be possible if the US shop produced an Export CofA. This is a form signed by a US DAR (Designated Airworthiness Representative) and in the USA it used to cost about $300.
Otherwise, installing a used part (even if it is your own engine or any other part which has been overhauled or repaired) needs an EASA-1 form. I am looking for a reference for this… might be something called MA613.
The Export CofA system is what makes it possible to put a used N-reg plane onto an EASA reg. Obviously the whole plane is “used” so some way must be found to import it…
However I heard a few years ago that the Export CofA system was stopped by the FAA, and this resulted in (at least) the UK CAA accepting Class 1 parts (engines and props) with just an 8130-3 form. However I have just heard from a US engine shop that the information about the CofA discontinuation appears to be be incorrect as of today.
Does anyone know any more?
Please, no more of the usual thread derailing about using a European engine shop instead!

If this were true, you could not put a N-reg aircraft onto the EASA register which you definitely can.
M.A.613 looks like this and has lots of AMC:
My knowledge is not good enough to answer this particular case but is it not quite common to accept Form 8130 these days?
I wonder if the last para above (2.2) is what is referred to in the first post here… the rest is inconclusive.
t is it not quite common to accept Form 8130 these days?
For new parts, yes. About that, there is no doubt. There is a point of view that such an 8130-3 has to be issued by the manufacturer of the part.

Yes; very true. The Q is: what is the route (if any) for a component.
9 years later, back to this one 
UK CAA acceptance of 8130-3 from the US
This guidance suggests nothing has changed for years. Brexit also changed nothing.
Specifically it means if you are G-reg and want your engine overhauled (or exchanged) by a US shop, that shop needs to issue a dual release 8130-3. That is a PITA since most US shops can’t do that.
There used to be another route where a US DAR issued an Export CofA. Does anyone know what happened to that?
I know the CAA (and all of UK ATC) read EuroGA so it’s a pity they remain silent.
This shows one potentially huge advantage of N reg which not many know about.
This link from the UK CAA website identifies US based repair stations that can issue UK 145 releases, https://www.caa.co.uk/Documents/Download/3895/873ad580-27fa-45b0-a682-396e7a2a2775/4612 it might contain engine shops
There are a number of US shops with dual approval but not necessarily the ones who do the best job.
