Too much association with EASA or perhaps pressure from the current administration to fall into line with other international regulators? It is hard to say
So the FAA said no because of their links with the EASA (and others dark powers) and the TCCA said yes because they don't have these links.
Again, interesting point of view.
So about the R66 for exemple, why the FAA said yes and the TCCA and EASA said no (until now) ?
