I did a BFR for a student who subsequently busted a TFR. Let's just say the FSDO was not happy. Luckily for me I had printed out a list of topics to cover as part of the ground portion as per the current FAA requirements. The student and I went over all of these topics and BOTH signed off saying we had done so. The FSDO was all over my a$$ until I faxed them a copy. I know there are plenty of CFI's out there who think once a student has a ticket all responsibility is passed on. This is not the case and they WILL make you take a ride or pursue certificate action if they deem it necessary. KEEP YOUR RECORDS!!!!
