Today I deburred the bottom flanges in the centre section bulkheads, the seat ramp supports (F-814E-L-1 and -R-1) and the corresponding holes in the two inboard seat ribs.
I deburred the aft and forward ends of the mid bottom skins, and finally finished off deburring the open holes in the forward fuselage sub structure.
