This comes mostly under the "this is too easy, better check" file. I fitted the firewall to the fuse today. Piece of cake, just as mating the center and aft fuselage was a piece of cake and just as fitting the side skins was a piece of cake and jsut as rolling the curve in the side skin was.....ahhh...well..not so much.
Anyway, the instructions advise to check that three conditions exist, not the least of which is "The forward face of the firewall is 5/8" aft of the forward edge of the F-770 skin."
OK, fine, but normally the instructions would say something like "be sure the flange of the firewall is flush with the forward edge of the F-770 side skin" because, well, the flange is 5/8". Right?
Now a harder question.
The next step in the instructions say "When all these things come to pass, drill the F-770 skin to the flanges of the firewall, starting at the top longeron and working toward the bottom. Since only one longeron, the top one, is installed at this time, and the thing is flipped over, I assume this instruction is the same as "start at the bottom where the longeron is and work toward the top" (as presently positioned).
Right?
I'd be flying this damned thing by now if I didn't double-check every little thing.
