Relevant part of EASA 1178/2011 reg. substantially sets that an IR(H) Renewal / Revalidation Prof. Check has to be performed to an ATO... Well, but there would be the need of an approved Instrument Rating Examiner (also rated on type I suppose). Helicopters for that purpose have to be EASA registered and IFR certified. Operational manual has to detail pertinent procedures, etc... No problem here in Europe, of course, but outside? Sure at this point I'll write soon to Atlantic helic., but I'm afraid I'll have to come back in Europe for annual EASA IR check. Anyway thanks to all for the help, I let you know soon if news incoming...
