F12-01R Right Hand Forward Side Assembly.
I first assembled the assembly with clecos. I then located, pilot drilled and clecoed F15-06 Doubler. I then up drilled those pilot holes to the #30 size.
Next I located, pilot drilled (#30 size) and clecoed F14-05 and -06 Firewall Attach Angles. I then up drilled those holes to 3/16th.
I also up drilled the hole through the Seat Belt Attach Gusset to the required 5/16th.
I clamped the clecoed assembly to the aft fuselage to see how it is going to look.
