But, as was said much earlier, the FCL regulations Annex III are about validation and conversion of foreign to EASA licences, none of which applies to third country licence being used to fly a third country registered aircraft, i.e. without any need for either validation or conversion.
Part-FCL says absolutely nothing about any requirement to obtain an EASA licence to fly non EASA registered aircraft inside the EU if you happen to be a resident of the EU, as many have feared. That does not mean to say there are not more regulations in the wings.
