I've seen and heard of "clipped wing" this and that - Cubs, Taylorcraft, etc. Do these remain certified, as in some sort of FAA field approval for the mods, or do they have to get into some sort of Experimental category? Or is there an STC for the shorter wings?
How is the "wing clip" done? Delete an inner-wing rib-bay and move the ailerons inboard? Or shorten the outer end of the wing, including the ailerons?
Just curiosity - I'm not working on trying to make my own or anything.
