As I mentioned earlier, I was so sure the three most aft Emp bulkheads (F-01410, F-01411A, F-01411B, F-01412A, F-01412B) were punched, but after looking at a picture from when I was prepping one of the bulkheads, I'm not 100%. I've been thinking of how best to make a more clear determination, before committing to removing them. I'd like to get others thoughts.
Looking at the LCP dimple cracking I have experienced, the cracks are easily seen with the naked eye, even after priming, that is, if you know what to look for.
However, once riveted in place, I can't see the cracks. Therefore, I am thinking of drilling out a number of rivets, and inspecting for any sign of cracks. If I find a crack, then I'm done inspecting, and need to start planning for removal. If I don't find a crack, how many rivets do I remove and inspect, before making a final determination?
These bulkheads are some important structures, which I think will be difficult (not impossible) to get out clean. I fear compromising the skins in the process.
Any thoughts would be appreciated.
