As far as the value of our planes go, I don't think it will make much of a difference. There are a lot of planes available under 180 HP that can hold one passenger.
I am optimistic, too, but then every year I thinkI am going to win an airplane.
Because there are so many four seat, fixed gear < 180 hp planes, the spike in value will be a general one, but I think it will be significant. I also think it will be the death knell for the LSA. It is possible, though, that Cessna and Piper will be the ones who oppose the change, as the market will again be soft for building small planes and they will still be on the hook to maintain the old ones.
