RV12 Page 17-02 steps 4-7 , reference Figure 1
This is for newer RV12's and can be a retrofit for older models. When riveting the W1201A Doubler and bottom inboard wing skin to the wing spar and rib underneath, the most inboard rivet calls for CR3213-4-3. The problem occurs when I pull the rivet, it doesn't grab the flange of the wing rib underneath, the shop end pulls right through. It's happened twice now. I'm wondering if I can drill #40 a small piece of scrap to use like a washer underneath since it pulls right through the #30 hole in the rib flange? Has anyone else experienced this problem? Also, I'm guessing I can't use a LP4-3 because it's not the right spec for strength? Help please!
