Brief Description: Right side Flap Brackets Fab and drilling 3
Once the brackets were all drilled #30, I opened the one hole up to 1/4 inch with the step drill bit. Finally, I dug out a K1000-4 nutplate and match drilled using a shop bolt to hold the nut plate snug. I then used the counter sink on one side and a dimple for both the rib and nutplate.
Finally, I adjusted the bend.
