Just be cooperative with them, give them the information they request, be proactive, be enthusiastic about learning from the experience and you will be just fine. If you do all of that the worst you get is some retraining. The FAA doesn’t really suspend or revoke anymore. Only if you are avoiding them and denying what you did or did it intentionally will they do that. Trust me the FAA are not monsters. They have a new compliance culture that they are trying to grow. Do what I said and you’ll be just fine, no worries.
I may be wrong about this part I’m not 100% sure about this but if you are offered retraining and you successfully complete it I believe that doesn’t even show up on your records as enforcement, or if it does that it is taken off after two years. It’s really not a career ender at all. All pilots are humans and humans do stupid ******, learn from it. It’s ok.
