After a failed leak check on one fuel tank this weekend I decided to cut an access hole in the baffle, seal the leak, and fabricate a doubler and cover plate similar to the access plate on the root rib. However, in cutting and shaping the new hole in the baffle, lots of aluminum chips/dust were created and seemed to really like to stick to the still slightly tacky proseal fillets inside the tank. I cleaned up the area pretty well using wet cloths and a vacuum, but I'm concerned that debris may have made its way into the adjacent rib bays where I'm unable to see/clean it.
Interested in getting some expert opinions on how best to deal with this. Right now I'm thinking seal up the tank, pressure test again, and upon passing fill with water and drain several times. Perhaps standing the tank on end, full of water, will let any debris make its way down to the drain valve, whereupon I can remove the drain and flush out the debris. Wondering though if fuel might not be a better flushing medium/solvent.
Thoughts? Thanks in advance!
