CS-7 mounting


I now have quickie on the brain, if i relax a little i start thinking about the project.
One thing i noticed as im pulling aileron linkages and ailerons is i wasnt happy with the CS-7 (ill call assembly) mounting. I could deflect it up and down without much force.
It looks like its mounted to the bulkhead fs94 which if im correct is only covered by 1 bid layer. Now as i look at online plans it looks like it should be mounted to the main wing shear web and notched into the bulkhead.
Am i correct on this?
