After deburring the left wing outboard leading edge ribs, I test fit one of the ribs into the skin. I noticed that the leading edge was still somewhat tight and wanted to avoid any dimples showing in the skin after clecoing.
To take care of this remaining faceting in the tabs, I went back and forth to the deburring wheel and removed additional material around the tab bends. After a couple of trips, the ribs fit nicely and I saw no issues with any skin deformation at the leading edges.

Placing and clecoing the leading edge ribs to the skin was fairly straightforward as I had taken a lot of care to ensure the rib flanges were fluted adequately. I made sure that the ribs were oriented correctly and decided to cleco every hole to ensure everything was held tightly for drilling the J-channel stiffener.

 |
| Splice strip clecoed between the skin and rib. This took longer to cleco as I had to make sure 3 holes were in line when placing the cleco |
 |
| Skin stiffener (right) passed through rib notches and match drilled to skin |
 |
| I noticed there was no rib hole that matched the top skin hole. After double checking the plans, I match drilled these holes as well |
After completing the match drilling on the left outboard leading edge assembly, I got to repeat all the steps on the right outboard leading edge assembly!

| Right W-1009 1R and 2R ribs marked for trimming |
As I had done on the left, I temporarily clecoed the 1R and 2R ribs to the main spar after trimming to check clearance from the step bars and rivet heads, this time taking some photos. Everything looked good!
 |
| W-1009-1R clecoed to main spar. Trimmed ends clear the rivet heads by about 1/32" |
 |
| W-1009-2R also clecoed to main spar, with same clearance from rivet heads |
The preparation, assembly and match drilling of the right outboard leading edge went smoothly. Now on to disassembly, final deburring and dimpling.
 |
| Left and right outboard leading edge assemblies fully drilled and ready for final prep before priming and riveting |
 |
| Both leading edge assemblies once again reduced to a pile of parts |
All remaining holes in the skins, stiffeners and ribs were deburred, and dimpled using the DRDT-2 and pneumatic squeezer.
