If I understand you correctly, you want to fly an aeroplane on a validation of your FAA ATP. Stand to be corrected, but if that is the case, you can only fly and aircraft on a validation of your FAA license if you have a type rating for that aircraft on your FAA ATP. In this case it is not certified in the US so it is not on your FAA certificate. This means you cannot fly it on your FAA license, or use your FAA license validation to fly it.
