Brief Description: Installed rear spar and riveted ribs
Countersunk the flanges of the HS rear spar. Installed the spar in the HS (this time clecoing the skins as well aw the ribs, so that un-countersunk holes would not go unnoticed) and installed the pulled rivets in the rear spar. Riveted the tip and inboard ribs to the skins. Only the AN470-AD4 rivets and the flange/skin rivets remain.
