Since December 31, 1999 all US aircraft are Stage 3 compliant or on the ground. There are waivers for maintenance and non revenue, but highly restricted.
But then you have to go and be a ****** and get antagonistic. All I said was that I THOUGHT all aircraft entering the USA had to follow FAA guidlines just like N registered have to follow the laws of other countries.
At least admit your ignorance, because you obvioulsy know little of either catagory.
