Time: 8 Hours
I needed to run the pitot(airspeed) and AOA(angle of attack) lines inside the fuselage and the left wing. I decided where I wanted to run the lines and drilled for two snap bushings at each bulkhead as they went aft from the fuselage side where they will make a 90° and exit to go into the left wing. Once I had the bushings in I ran the lines and secure them with zip ties as needed to keep them out of the way of things like the flap push rod.
I also needed to reroute the two lines in the wing as I had originally followed the tooling holes in the ribs. The problem with this is it puts the lines exiting the wing too close to the wings spar. Glenn had already figured this out so I adjusted mine like his. I just change the location of the innermost rib snap bushings. In between the last two ribs I rerouted the lines to exit in a better location. I used a #6 adel clamp to secure the lines to the rib. These lines will be cut to a perfect length once we reinstall the wings for the final time and slide thru the snap bushings in the fuselage side. They will attach to the two elbows that will be inside the fuselage.
While I was working on the right wing and the pitot/AOA lines I decided to work on the wiring that I needed to run to the pitot and wing tip. On the right wing I will need a 3 wire harness to the tip for the land/taxi lights, a 3 wire(with shielding) harness to the tip for the NAV/Strobe and a 3 wire harness to the pitot tube for pitot heat. At the wing root I used plain Molex connectors as this area should be sealed up from moisture with the rubber seal that will tie the flashing to the fuselage side. Out in the wing tip I might get moisture thru the hinge that I have holding them on so I used Seal-All connectors form McMaster Carr to help prevent corrosion. With the NAV/Stobe I carried the shielding thru the wing root connector and left it un-terminated at the wingtip as per AeroLED’s recommendation. I started with all the Molex connectors at the wing root and secured them with a adel clamp.
When we go to attach the wings for the final time I left enough length on the fuselage side to be able to connect the wires with plenty of space as we slide the wings in place. Then as the wings slide into place the extra wire will be pulled into the fuselage and out of the way under the passengers foot wells.
Once I had the wing root wires secured I moved to the outboard end to work on the weather proof ends. They work just like a Molex except the have a rubber seal that you put on the wire before crimping. Once the wire is crimped you crimp the seal to hold it in place.
These seals fit nicely into the back of the connector and prevent moisture from getting in.
Then there is a back peice that snaps into place to hold the wire and seal in place.
I completed this process for both the land/taxi lights and the NAV/strobe lights and secured them with an adel clamps and zip tied the remaining parts in their bag to the harness so I don’t loose them for later. Then when I get my lights bought I will complete the mating end of the connector on the wires from the lights and make them long enough to connect them as I install the tips.
I also ordered the Dunon ARINC module, the device that talks between the Skyview system and a certified GPS, so that I could drill and mount the nutplates to the bracket I made a while ago. I really didn’t need this part but I wanted to rivet the bracket to the fuselage and I needed the nutplates to be drilled first.
