Brief Description: 0Reassemble and Rivet L & R Spars to Wing Ribs
15-4: Step 4: Reassembled parts riveted per the rivet callout. Riveted the L-Spar first and found that the callout for the W-1007D-L holes common to the rib flange, AN470AD4-5, were a bit long so after a few on the L-Spar and all of the R-Spar subsitituted AN470AD4-4.5 length. Also found the same on the AN470AD4-6 rivet callout on the holes common to the inner aileron bracket. Substituted AN470AD4-5.5 legnth rivets instead after trying a few. All rivets were set with pneumatic squeezer except holes common to most of the aileron bracket and some of the corner rivets on the inner ribs of flap brackets. Set all rivets with manufactured head to the rib flange side except of course for the W-1007C counter sunk rivets.
