Brief Description: HS Front Spar Service Bulletin (SB 18-02-02) log
I attached all the hinge brackets and clecoed the gussets into place. I drilled each of the holes as directed with high speed and light pressure. I saw where some had kept all the inboard side rivets on the gusset with #40 for use with AN470 rivets, but I decided to stick with the SB as defined. I then removed all the hinge brackets and cleaned everything up, including the inside of the spar (as best I could). The gussets are prepped and I’m now ready to rivet them into place and put everything back together. I expect that will be the real challenge.
