Brief Description: Drilled #40 Holes along Side of Fwd Top Skin
I measured and drilled #40 holes, then #30 holes, in each side of the fuselage aft of the instrument subpanel along the longerons for the forward top skin. The holes were located between the existing rivets in place on the QB fuselage. I clecoed the top skin in place and used the strap duplicator to drill the matching holes in the skin on each side. The holes were deburred and dimpled with the pneumatic squeezer. The holes in the fuselage were countersunk.
