My A&P friend noticed surface corrosion on the wing and tail mounting hardware on his first quick walkaround when I first bought my Mod IV. So I've got hardware to change! As I'm not the original builder I have none of the original plans or parts list. I'm assuming the wing strut bolts, top and bottom, are close tolerance. And at a casual glance, the upper strut bolt and nut look impossible to change as they are half hidden in the wing covering. And then I start wondering about the proper torque. And then that leads me to wonder about the mounting hardware at the leading edge. It came with castle nuts and safety pins. Is that normal?
Thanks,
Jay
