Riveted the F719 Angles to the F719B Stiffener. Did not rivet the assemblyto the vertical angle of the firewall because I forgot to drill the hole when everything was assembled. Will have to remember to drill the hole before putting the skins on.
Worked on the F904H plates which I had to reorder because I countersunk them wrong the first time around. Clecoed them on and drilled holes. Removed and deburred and countersunk the holes correctly this time.
Discovered that I had a lot of holes that I had not drilled yet because the plans were unclear when to do so. So I re-clecoed on the F970 skins and other pieces and drilled all remaining holes. Also drilled the F920 armrests although I couldn't find when it should have been done. It just made sense to do it now before I dimpled the skins and riveted them on permanently. Hopefully I now have all holes drilled that need to be drilled.
Disassembled the center section and the aft section. Removed the big longerons. Cleaned things up and called it a good day.
