Vans Aircraft RV-12 Airplane Build, Section 31: Fuselage wiring (part 12)

Reference: Pages 31-13, 31-15, 42D-19; 2.5 hours

There seems to be light at the end of the tunnel and it is not a train! The Van RV 12 is going well.

Step 6: Make two Wireway Foam Strips from FOAM 1/6X1/4 V1110. Adhere the wireway foam strips to the top edges of the Over Rudder Wireway.



Step 7: Install the Over Rudder Wireway just left of the Inbd Rudder Pedal Block. Do not over tighten the screw!



Builder's note: I found using a small screw driver to align the Wireway to be very helpful as pictured above.

Step 8: Remove the two bolts and washers holding the Inbd Rudder Pedal Block halves together. Slide the bolts through the holes in the Wireway Bracket flange then reinstall them. Tie-wrap the main wire bundle to the wireway bracket.

Step 1: Rivet the F-12122 Artex Elt Bracket to the F-1204F-R Aft Side Bulkhead.



Reference: page 42D-19

Step 1: Attach the WH-00036 Tunnel Conversion Harness to the WH-RV12-TUNNEL harness using ES-00164 D-Sub Backshell Interconnects. Place a drop of blue Loctite on the threads of each thumb screw then fully tighten them into the d-sub backshell interconnects.



Step 2: Attach the WH-00026 Option Conversion Harness to the WH-RV12-OPTIONAL harness using ES-00164 D-Sub Backshell Interconnects. Place a drop of blue Loctite on the threads of each thumb screw then fully tighten them into the d-sub backshell interconnects.

The step above was completed back on October 1st.

Step 3: Tie-Wrap the WH-00036 Tunnel Conversion Harness to the WH-00026 Option Conversion Harness where the wires exit each backshell.



Step 4: Tie a note to the cushioned clamp to tie-wrap the WH-RV12-TUNNEL harness to the wires going through the cushioned clamp near the left ES CPU FAN on either side of the clamp when all wiring has been completed in Section 42C. This will allow the update harnesses to be moved during installation of the SkyView avionics system.

This completes page 42D-19. The last step confused me for sometime. So now that I get it, I going to add a note to the Tunnel harness that says " Tie-wrap the Tunnel harness to each side of the wires going through this cushion clamp." That's it for now.

Vans Aircraft RV-12 Airplane Build, Sections 42D: SkyView Update (part 3)

Reference: pages 42D-19; 1.5 hours

I'm starting back into the wiring update for the SkyView EFIS on the RV-12 aircraft.

Step 1: Attach the WH-00036 Tunnel Conversion Harness to the WH-RV12-Tunnel harness using the ES-00164 D-Cub Backshell Interconnects. Place a drop of blue Loctite on the threads of each thumb screw then fully tighten then into the d-sub backshell interconnects.

I actually did this while attaching the tailcone, because I needed some of the wiring for the tailcone before attaching it.

Step 2: Attach the WH-00026 Option Conversion Harness to the WH-RV12-Optional Harness using D-Sub Backshell Interconnects. Place a drop of blue Loctite on the threads of each thumb screw the fully tighten them into the d-sub backshell interconnects.



Step 3 & 4: Deal with adding the cushion clamp and Tie-wrapping the harnesses. I will complete these after all the wires are ran.

Step 5 (lighting kit installed): Find the WH-L435 (YEL/PRP) and WH-L436(YEL/GRN) wires coming from the WH-0026 RV-12 Option Conversion Harness. Dut both wires three inches from the d-sub connector they are attached to. Cover the end of each wire in heat shrink.

Builder's note: I just removed them from the harness.



Step 6: There are several long wires left coming from the WH-00026 Option COnversion Harness and WH-00036 Tunnel Conversion Harness. Route these wires down through a snap bushing in the Panel Base then follow the path of the WH-RV12-TUNNEL harness theough the to the F-1202F Bulkhead. Use the new wire run holes made in this section to route the harness to the aft side of the F-1203A Bulkhead.



That catches the RV-12 up to date. With the weather turning colder I may jump over to the canopy and finish it up before it's too hard to heat the grage up to 70 degrees. So long until next time!
