Your correct, I looked at every wing I have that use a tube (8 or9) and this is the only one with the tube not built into the spar structure. I don't think the tube is to short for the intended service. Question now is what is the best way to correct this defect. Looks like I will have to strip the bottom covering off and move the tube forward with supporting structure to transfer the load to the spar. Not a huge project but....
