Measured, trimmed, and set rivet lines for the two forward seat panels. There were 3 rivet lines each: One attaching to the wing Center Spar, one line attaching to the Gear Channel, and one attached to the side skin. Once I drilled them out at pilot hole size, I updrilled all lines to final rivet size to regather the clecoes.
I also updrilled the rivet line where the rear fuselage bottom skin, gear channel, and seat back all share the same rivet line. You can see this rivet line in images 1 and 2 - the line just aft (to the left) of the forward seat panels.

Looking forward. The gap between the seats will contain the armrest.
From the outside - a new rivet line on each side skin next to the yellow line I added to the pic.
