The (now) A220 is a clean sheet airplane designed by neither Boeing nor Airbus. Introduced to the US market. Boeing did some non-FAA bullying which forced Bombardier to sell the program to Airbus.
It's not impossible, but it killed Bombardier. If anything, it proves their point! Airbus now has a nice plane, but Bombardier basically lost everything and has been sold for scraps. Airbus won by not doing anything and letting someone take the massive pain of going with a new design.
Now of course what Boeing did to block Bombardier didn't help* and more or less sealed Bombardier's faith. But that was only because Bombardier at that point was basically on the verge of death and had only a few months left of runway (ha), which is crazy for a formerly massive and diversified player.
* and our government here in Canada is so weak (nothing specific to Trudeau here, the same could be said about Nortel or tons of other high tech that have been squandered in Canadian history ) that it didn't want to support bombardier more than it did.
Your point, correct me if I'm wrong was: FAA regulations are about regulating safety to the max, but not taking into account business realities and not evolving, new ones are added but old are not reviewed. Therefore only established super-well capitalized companies can play.
What killed C-Series was Boeings shenanigans about 300% import duty. Abusing US laws for sure, but nothing to do with FAA killing it.
The plane was ready, so they had already done it. So whatever you say about not being impossible is directly contradicted.
Would Bombardier have made it with a more cooperative FAA? Maybe. Same question could also be asked about whether a different airline industry in the US would have helped. We don't know and never will.
In general tho, I am not arguing against the overarching point of your original comment, regulations tend to come in and it rarely happens that they are being refactored or cleaned up.
A lot of paper is being pushed around and rigidly enforced without looking at the big picture. The friction of complexity I guess.
But the specific claim, even though it sounds about right is not strictly correct.
Itβs not impossible.
