SPAR -OUTBOARD

Picture
The right and left outboard spars.Just beginning to rivet the left

Reverse sides,still oriented right and left i.e.
your standing in front of the plane

ONX-W09
Outboard Wing Panel Substructure

Pretty straight forward assembly here.Make sure to eliminate all stress risers on the small parts.Check the revisions for this page.
Note orientation of the bolts.
Picture
I would recommend putting the second set of ribs in first.You have to bend the rib back a bit to get the bolts in past the rivet stems and you won't be able to do that with the first rib in as that channel will not allow you to bend the rib back.Trust me on this.Been there did that.
