No, I really mean that if it can be seen, it can be worked on. So according to Cessna if say a control cable pulley can just be spied through an access panel 2 feet away, then by golly there's no problem working on that pulley even though you can barely touch it after really stretching and contorting yourself.

Sometime I really have to fight the urge to call Cessna up and ask them what the hell they were thinking of when working on their planes.
