Brief Description: Redrilled Inboard Ribs for F-648 Plate
Double-checked position of holes drilled on inboard ribs. Found that the F-648 center cover plate cannot be drilled to those ribs in those positions. The ribs need to pulled inward and centered on-line. Laid out proper position of ribs to floor skins and F-648 center cover plate. Drilled pilot holes in floor skins and then drilled them to the ribs. Used hole finder and #30 drill bit to drill holes in cover plate. Deburred all holes. Measured and cut six hinges for floor attach points for seat backs.
