Some states require registration/insurance on the plane. I think it’s a one year in jail misdemeanor in Maryland or Virginia.
pretty sure I saw a few articles on people flying without pilot certificate and the fine was 250k plus a fun stay with the govt
Correction on Maryland and registration. Yes they passed a law in1977, effective in 1978, state registration required for all aircraft owned in the state.
Appealed, and found not valid.
I have in my logbook the registration document for N3891S, for 1978, which I removed and kept for a souvenir. From the number on it, 0474, at least 474 owners ponied up, just to stay legal. We did not file to recover the fee, the cost would have been more than we recovered.
