With all of the discussion about the wall thickness on the landing gearhinge points, I went down and measured . Mine are made to thePietenpol prints.The remaining wall thickness on my fittings andmatching gear is .090" , final drilled for 5/16" bolts. That seems likeits plenty of meat to me. Just remember, that narrowest wall is never being pulled on,( intension) , when on the ground ,or for normal landings. Both thick sidesare in compression. There won't be very many times that piece will bepulled on. If it's true that a Piet has never had an accident , in 70 years, dueto a problem with design, then that means that one of these has neverbroken.Walt EvansWith all of the discussion about thewallthickness on the landing gear hinge points, I went down andmeasured.
