The first tasks this morning were mostly deburring of various components including the F-819-1 aft deck, F-810D-1 and F-811D-1 spacers, the F-888 left and right mid-longerons, and the F-889 left and right lower longerons.
The seat belt bracket assemblies (completed earlier) were clecoed and then match drilled (#12) to the F-857C angles and the left and right lower longerons.
