Brief Description: Created capture for rudder trim hinge
I had been pondering how to do this without adding nutplates, etc. into structure already closed and difficult to work in. Suddenly, the solution hit me. The hinge is captured at the top end by the rib above it. What I needed was a way to keep the hing from travelling down into the bottom fairing and yet be removable should I need to work on the tab. As you can see, I bent the excess hing wire into a box shape with a little forward-facing hook at the end. The box isn't square but can be squeezed together to allow the hook end to go into a hole in the bottom rib (Image 2). Now the hinge cannot move up or down and the sping action of the wire keeps the hook firmly in place, yet it can still be removed by hand if required.
