Riveted the HS-609PP bars to the HS-603PP spar channels being careful not to set rivets where the HS-706, HS-708, and HS-405 ribs will be. I covered these holes with tape as well as the holes where the HS-412 hinge brackets attach. After those rivets were set I then went ahead and riveted the HS-412PP and HS-413PP hinge brackets using the correct size rivets for those.
