If it is a phone call it won't come on a weekend or holiday. It will probably take at least 2-4 weeks for the feds to get their notes together. First comes a phone call basically making sure you are the right person, and then explaining what happens next. You may be asked to write a quick paragraph giving your side of the story. Don't do it. That is just a quick confession from you to make their job easier. Don't refuse, at the very least say you will see what you can come up with.
Then about 4 to 6 weeks later you will get a registered letter from the FAA, a Notice of Proposed Certificate Action from regional, in the letter they will throw the book at you with probably careless and reckless (91.13[a]), flying into a TFR, failing to do pre flight planning and a 120 to 180 day suspension. Some folks will tell you that hiring a lawyer will only pizz off the FAA. Well, the FAA has thousands of lawyers working for them so why shouldn't you have just one, if just only to advise you. I mean the violation is pretty cut and dry. You won't get a verbal spanking over the phone.
After the Proposed Certificate Action letter, you will have a choice. You can accept their terms or ask for an informal conference, usually done over the phone. Then this is where a lawyer helps you to negotiate the punishment. The informal conference will be with a FAA lawyer, so remember that this is a civil, not criminal matter. They do not have to advise you of your rights. They know all the tricks to get you to confess. At this point negotiation is the game being played. Be professional. Don't argue. Ask questions if you do not understand something. You want the punishment to be as less as possible, the FAA lawyer wants to show something was done. Understand it was the Secret Service, not the TSA, that requested that the FAA impose a suspension for even first-time TFR violators. In most cases the FAA assumes you are a pilot who has unintentionally made a mistake, and that you will benefit from counseling or training to mend your ways. The Secret Service assumes you are a potential threat. Understandable but it could learn from the FAA's experience that a softer glove is more effective.
I am guessing you just hold a PPL so then this may turn into an educational moment instead of punishment. Hopefully all you will have to do some remedial training with an instructor.
Filing a NASA form is good. It won't stop the violation from going on your record but for most offenses this will waive a suspension.
Good luck to ya bud. This won't be fun and painless. And keep us informed.
What a bunch of malarkey
