Hi all,
I am having a confusing moment!!
I?m riveting the rear spar to the left bottom and right top skin on page 9-20.
Back on page 9-18 step 5 and 9-20 step 2 we leave 6 holes in the bottom skins / rear spar of each elevator free of rivets so we can get access to the tip end to do closeout on page 9-22.
I have read and re-read the pages from when we leave the holes open to when we finish closout on 9-22 and I can?t for the life of me see where we rivet these remaining 6 holes on each side?
I assume they have to be done before 9-23 Step 1, as this is where we add in the foam ribs and trailing edges.
Can anyone point me in the right direction? If not I?ll close them up once I?ve done with page 9-22.
Also, why do we use pull rivets for the bottom skin / counterbalance holes (and solids on the top)? (9-22 step 4 and step 8). Seems weird to use pulled rivets on the bottom but solids on the top? Is this just cosmetic?
Thanks for the help in advance!
