No, it’s the other way around: if the law is adopted, the fuel manufacturers/distributors would have no choice but to start ramping up unleaded fuel production. Manufacturers of GA airplanes and engines would have to make sure unleaded fuel is properly STC’ed instead of pretending it doesn’t exist and it’s not their problem. Once this happens – these communities will lose their convenient excuse (and I agree – they do use it a lot).
Let’s solve the problem; we have the tools. This is a good law; as an operator of a GA airplane, I support it.
