Ok guys maybe this has been covered before. I just did some repair work on an old early 80s RV-4 engine mount, the right tube that comes up from the top of the gear leg socket to the bottom of the engine was broken thru and had all the paint polished off, it had absolutely no deformation, not flexing or bent, the same tube on the other side was cracked also, about 2" above the weld, well out of the heat affected zone, right where a zip tie had worn thru the paint and you could see it had abraded the tube right where the crack had formed, the surface of the tube looked like it had been work hardened promoting the crack.
My old -4 has a bunch of zip ties on the engine mount too, I will be inspecting and eliminating these before further flight!
