Don't get me started on the NY port authority! They sent a several hundred dollar bill for a plane I previously owned. In their own letterhead the tail number of the aircraft being bulled was not the aircraft I previously owned. Was close though. After a dozen or so back and forth emails trying to explain to them my plane has never been to New York, that I did not own the plane at the time of the bill, and that I never owned the aircraft with the tail number in question. They finally stopped. But this was over an 18 month span. Unbelievable the amount of incompetence at a government agency...wait... nevermind. I'd expect nothing less.it would be Port Authority of NY. . . good luck getting anything from them. Apparently they track the tail numbers and use the FAA aircraft database to send the bill to. . . I imagine the previous owner will forward the invoice, but was trying to get ahead of this so they didnt have to.
