I have made a couple of sketches below to aid in the understanding of
|OK. So the problem occured about three rivets inboard of the end of the doubler on the rear spar. The pneumatic squeezer pushed so hard on the flange that it punched a hole the size of the dimple die (about 1/2") in the flange. I cut this area out, polished the edges, and made a doubler strip shown in the next drawing.|
|This drawing shows the shape of the notch I cut out (it does not extend
into the web at all). The red part shows the doubler strip I want
to rivet underneath the flange. I expect .040 or .063. I will then
make a small piece to perfectly fill the notch. That will be riveted
to the doubler strip.
The question is, will this fix be strong enough, or do I need a whole new rear spar (which means removing the current rear spar).
