So your asking all the aircraft manufactures to redesign all their aircraft, taking performance penaltys to make a safe spinning aircraft?? Dont think it will happen. Its possible to make an aircraft almost spin proof, such as the Schwiezer 2-33 sailplane, but then what would be the value of spin training with a plane that wont spin?

You are right of course, it won’t happen but basically what I am saying is that any new designs for basic training aircraft should be cleared for deliberate spinning as part of the certification process. It is certainly unreasonable to expect the manufacturers to redesign types thatare already in production due to the expense involved. The reason I say this is that people do not always stay with the same type of aircraft all through their flying life and if they learn on an unspinable machine they should undergo spin training before being let loose solo in a machine that is spinable
