Brief Description: Fuselage - Seat Rib skin F826 & F827 prep for rive
In preparation for riveting skins F826 & F827 on seat rib frame sub-assy, I lay out strips of making tape on both skins around each frame flange. Purpose of tape was first to prevent bucking bar tool marks, but also mask for faying surface sealant squeeze out. I did that because I decided to but sealant between frame flanges and skins in order to prevent condensation to sip in between and cause corrosion later.
