I'm working on the mid fuse bottom skins and while maneuvering around the shop I managed to put enough pressure on one arm of the fuselage bulkhead (page 25-8) to change the angle of the gusset holding the two pieces together. I gently bent it back to the proper angle and noticed what looks to me (an untrained eye) like the gusset is now forming a stress crack. It's not cracked yet but the aluminum is discolored and I don't like it.
Do I just put a doubler plate over this or should I reorder the gusset and replace it? Note that it's in a tight spot to drill and re-rivet so any additional advice is welcome.
Close up what I believe to be the start of a stress crack.
For context:
