Today I spent an hour or so fixing some bad rivets I had in the left wing spars so far. After that I clecoed the left rear spar assembly with all it's pieces--doublers, aileron hinge brackets, etc...--to the main spar and ribs. Next I riveted the rear spar to the ribs as shown in step 4 on page 15-4.
Rear spar clecoed on and ready to rivet.
