Drilled the 6 holes in the R/H taxi/recognition light bracket and slat skin to a #18. Dimpled the 6 holes in the slat skin for #8 screws. Used a #8 nut plate jig to drill the nut plate holes in the mounting bracket. Dimpled the 6 mounting bracket holes for the #8 screws. Dimpled the #40 rivet holes for MS20426-3-3 rivets. Also dimpled the nut plate mounting holes. Rivet the 6 nut plates to the mounting bracket. I'm as far as I can go on the slats for now. I'm going to wait for the wings to get done so I can see how they fit and attach them together. I want to paint the slats before I install the taxi/recognition lights.
