Decided to work the control surfaces instead of the tail cone.
Dug out the left flap & aileron along with associated ribs and flap actuator.
Positioned, drilled, deburred, and riveted rib SNX-W06-02 and SNX-W06-04 drive plate to make SNX-W06-05L subassembly.
Superbowl Sunday, didn't feel well, so got a late start, and was called in to work for an urgent correction. Oh well; they say that as long as you make progress every day, it will be OK.....
