If that pawnee like ours was still flying under a restricted catagory you can tell the feds to take-a-hike. As a duster, and under restricted airworthiness we still have alot of latitude. We operate under much of the old CAA regs, meaning we can modify a hell of a lot as we see fit. I remember years ago getting a ramp check from some little Barney Fife type. Guy never recognized that the left door on the taylorcraft was completely different than the right one. Only thing he was worried about is my not having a compass card!
