The FAA oversees every flying object in the US. Not just new models, but also config changes to existing models, continued airworthiness, all the design org and production org certification of manufacturers (per site) and suppliers (again, per site). Which is quite a workload, especially in a world as complex as aerospace.

The point remains.

What point? That the FAA screwed up? That Boeing intentionally lied? Those were nver in question.

If it is the point that the FAAs job should be easy because the only oversee Boeing and Airbus, well that point is just ignorant.

If you're unable to understand LattleLazy's point it's probably best to refrain from responding to them until you do.

Attacking the poster is not moving the discussion forward!

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.

The FAA oversees all portions of pilot licensing, airplane manufacture, airplane service, operations, traffic control, idiots with drones, etc, for general and commercial aviation in the entire country.

Certifying new commercial models is but a small portion of what they do. By number of employees and budget I would bet that ATC is actually their biggest responsibility. That's not to say that they should just rubber stamp all that...
