F11-01 Fuselage Box Assembly.
I located, pilot drilled and clecoed the Upper Firewall Assembly. I had to do some trimming to get it to fit.
I made the P13-08 Hinge Half that go on the lower firewall. I located, pilot drilled and clecoed the hinge half to the firewall.
I up drilled to #30 the Firewall.
I also up drilled the lower skin those holes required to be #30. I marked with blue tape those side holes that do not get up drilled at this time.
