The parts do the same job as that welded brace on your plane, so you should be good, assuming that both bellcranks have a similar brace as in the photo. Your brace is at least as strong as the the ones provided in the kit from Kolb. My plane has no braces attached to the end of the bellcrank pivot bolts. I can see how the bolt or the weld could be weakened over time due to the repeated bending loads from the bellcrank. The kit from Kolb includes two braces and the pop rivets needed to attach them to the root tube. The rivet holes are not drilled in the braces. One of the braces needed to be modified with a rotary file in order to fit on my 1985 Firestar. On my airframe, there's a little piece of tubing that secures the fuel tank welded about 3/4" away from the aileron bell crank. The new bracket needs to be filed down by at least 1/4" in order to clear the fuel tank brace tube. I think I can make the Kolb bracket work. If not, I guess I'll weld on a bracket like yours. I applaud Kolb for taking the initiative to identify and engineer a fix for this problem. -------- There is something fascinating about science. One gets such wholesale returns of conjecture out of such a trifling investment of fact.
