After the last session fitting the gear leg mounts I started today by deburring the gear leg mounts, the F-7101 gear attach webs and F-770 forward side skins where the holes for the gear leg mounts were drilled. I then began the countersinking of the longerons. I countersunk the F-713, F-719 and F-772B longerons. I also countersunk the F-796C spacers that are part of the fuel tank forward inboard attach bracket installation.
