That there's multiple other airplane manufacturers, not targeting the "large passenger jet" market, but more towards the "general aviation" market?

Textron (Cessna, Beechcraft, hawker), Piper, Carlson, Viking, ... There's dozens of aircraft manufacturers (I have intentionally not listed those who make hit planes, but I think they too fall under FAA checks).

I would not actually be surprised if the small airplane manufacturers puts substantially higher load on FAA than Airbus and Boeing do.
