in build manual for 2007 Super Sport the figure b-12 I think for the aileron bell crank assembly shows the bolt coming from bottom and nut on top. I am new to this kind of work and I was lead to believe that any bolt and especially one on something this critical should be installed from above so if the nut did happen to come loose it would not drop out of the hole and make the control of the aileron or whatever impossible.
What am I missing here? Is there some reason this bolt should be installed from bottom up?
