Brief Description: Wing Center Section 7 – 18 plate nuts
This is a pretty basic task at this point in the build. Not a lot of pondering to do. Open up each screw hole with a #19 bit, open up the rivet holes with a #40 bit, countersink each rivet hole, debur, and finally rivet with the squeezer. I used a sacrificial screw and plate nut to help center the counter sink tool. No issues.
