Fairings, Wing wiring, Flap hinges, AOA tubing, Seatbelts, Fuel lines, Door latches

 A couple of fiberglass fairings were trimmed to fit.  These fairings connect the butt rib to the windshield and clean up the area there.  Attachment holes were drilled in the fairing and the windshield using a drill bit for plastic.  After trimming, pinholes in the fiberglass pieces were filled with dry-micro.

The navigation and beacon lights were installed in the wing tips and wired up to the switches in the panel.  A minor mistake was made by wiring up the green light to the pilot side wing, but quickly found this during test and swapped the lights so they were correct.

Previously we mentioned that the flaps had too much friction, so we reamed out the bushing holes slightly, and also found some paint overspray in wing holes that we reamed out.  After this work, the flaps now function nicely.

Flap hinge works great now

The door latches were painted a flat black (using plasti-dip paint) and one of them (previously drilled) was attached to the door.  The strut-attach brackets were also painted.

We ran into an issue with the tubing for the AOA line (which is run adjacent to the pitot line).  While working on the routing of these tubes along with the fuel lines from the wings, the blue AOA line got pinched when attempting to fold the wings, which tore a nice hole in the tubing.  We will repair this and adjust the routing to prevent this from happening again.

Seatbelts were installed and and all seatbelts torqued down.

We opened up the rear slot in tje butt-rib (using a dremel tool with sanding bit) to allow for the fuel fittings to rotate into position when the wings are folded/unfolded.  Hours: 28
