What happens if the FAA fines you $500 per day until you comply with their orders?
I continue to not comply, and the fines rack up. What else can I do? It's either not fly (in which case the case ends and I have no further ability to challenge) or continue to disobey.
Yes, the FAA can fine you, and when you refuse to pay it, you end up in administrative court where you aren't innocent until proven guilty, and your refusal ultimately ends up with the sheriff showing up.
Fortunately, I could be dead of old age by the time "ultimately" happens.
I'm aware of the Pirker case. It never made it out of administrative courts. This is going to be decided in a judicial court ultimately; there already are pending challenges in the DC circuit. But if I obey the FCC's arbitrary rule until those challenges go through, it's me who is on the wrong side of time; I could be dead of old age before those cases are resolved, even if they're resolved in my favor.
