Brief Description: Drilling firewall to fuse brackets
Drilled the lower firewall to fuselage brackets, the ones that hold the four AN-3 bolts, to the F-717 longerons. Good edge distance and clearance for the nuts all around.
Tweaked the bends and fit for the F-684 gussets and match drilled them to the skin and the F-713s.
Not too many parts, but a lot of tuning to get everything right..
