Seat rib assemblies started

Started today separating the seat belt attach lugs and supports. I then prepped all the seat ribs by removing small piece of metal in the lighting hole as per plans and then deburring all edges.  The seat belt attach lugs and supports were then riveted to the ribs.  Nutplates were placed as per plans.

Time: 2.25 hrs
