Not entirely right jtelling, before you start panicking the light aircraft pilots. Released by the CAA in their EASA workings update today:
"The Agency (EASA) also explained that there is likely to be a further extension to the opt out period for pilots holding third country licences used in non- commercial operation, to allow additional time to agree changes to the bilateral agreement with the USA."
Remaining rules are entirely to do with where the "operator" is based, and provided it (aircraft) is not in EASA-land for half the year or greater, then fantastic, a validation is not required.
Beaver 100 sums it up quite succinctly.
