Regarding the posts lately on cracking of the empenage on the 235-360's.We install a bulkhead/rib horizontally under the dorsal fin forward of the h-stab to make the tail a cone again .Greatly increases tortional stiffness and doesn't weigh much . Real hard to do though after the v-stab is closed .
We also strengthen the fuselage between the engine mount area back to the wing spar attach area . Another weak area of the small Lancairs .
While I'm at it , we are also developing a reinforcement of the cabin door on the IVP. Basically a carbon strap on the outside of the window vertically ,bisecting the window , similar to the Cessna 210 .
