I built my rudder 23 years ago and has the original 0.016 skins. I had a few cracks develop years ago at the first stiffener rivet just aft of the front spar. During this Covid isolation I have decided to re-skin my rudder with the 0.020 skins.
Lots of advise I have seen over the years on stiffener attachment to keep from getting the cracks, everything from pro sealing the entire length of stiffener to just a dollop of RTV at the trailing edge.
Obviously my rudder plans/drawings are 23 years old. Question I have is what do the current plans say? Do they still just say to just rivet on the stiffeners or are they calling out some type of goo?
