I want to put in an NAT intercomm in an airplane - however, they come with an EASA Form 1 instead of an 8130. I don't believe I can install this item... Does anybody know? I looked into this with Trig Transponders a few months ago, and found some FAA posting about a "Dual Release Form One" - where in Block 13 it mentions something about FAA data. I can no longer find that posting or regulation or whatever it was. I find a lot of stuff on the web about Europeans using 8130's with a dual release, but can't find about the Form 1 here in the USA.
I simply want to know for certain yes or no can I use Form 1?
