Brief Description: Dimpling fuselage frames and parts.
Today I dimple countersunk all the rear fuselage bulkheads F-807, 808, 810, 811A-1 and E-1, 812A-1 and C-1 bulkheads, where their rivet holes matched dimpled rivet holes in the rear fuselage bottom, side and upper skins. The various tabs that match with the longerons being left undimpled.
I dimpled the lower flanges on the baggage ribs that match rivet holes in the aft bottom skin.
