We are about to start recovering our C-47's rudder, we can't figure out how we should go about the area around the trim tab.
There are two bolts on each end of the trim tab that hold it on. However, the fabric goes over the area where these bolts are and there are no inspection panels in that area to allow access to the bolts for reattaching the trim tab.
One of the things we are thinking about doing is just putting in an inspection panel there, but looking at photos of other c-47's they don't have inspection panels either.
What was the process for this? Do you leave the area open where the flang is and then cover that after you have the trim tab in place?
