Completed chapter 22 except for page 22-03 step 2 to 4; attaching the firewall shellf to the firewall bottom. I will wait with that till I have some more sealant jobs to do. Also page 22-05 is not done; joining the FWD Lower Fuselage to the Mid Fuse.
This chapter is quite straight forward. The only thing I will do different next time is about enlarging the hole in the firewall with the unibit. It is easier to do this without the tunnel rib behind the firewall. First enlarge the hole, thereafter make the cutout in the tunnel rib.
