Vans Aircraft RV-12 Airplane Build, Section 35: Landing Gear & Engine Mount (part 4) & misc jobs

Reference: Page 52-02, 35-02, 21-18, OP-50; 8.0 hours

Another snow day! We are up to 18 inches here at the house, so when it snows you can make snowmen or work on the RV-12 airplane. The RV wins. I built the towbar kit this morning while letting the garage heat up. Also, today is a catch-up day of odd jobs.

One reason for building the tow bar kit at this time is there is a modification required to the nose fork if wheel pants are not bing added to the RV-12 airplane. I'm not going to do a step by step assemble of Van's Aircraft's towbar, unless it ties directly to the landing gear.

Step 5: Final-drill 5/16" the 1/4 holes in the nose fork. Installed the bolts washer and hardware as is supplied with the towbar kit.

That's all for the towbar and nose fork at this time.

Steps 3-5: Assembled the nose wheel for the RV-12 per plans.

This completes everything but greasing the main wheel bears on page 35-02

Step 10: Installed the fuselage steps using the hardware called out by Van's Aircraft.

Builder's note: I ended up opening the step holes in the fuselage just slightly so the steps would slide into place without deforming the sheet aluminum.

Another odd job I need to do is to mount the optional Fuel Pump Noise Filter to the floor of the RV-12 in the baggage tunnel of the airplane. The plans call for using RTV sealant , but this does not stick well to zinc chromated aluminum, so I used fuel tank sealant which sticks great.

Steps 5 & 6: Wire tied the Noise filter to the static tube and wires using the supplied tie wraps as outlined by Van's Aircraft. Then secured the noise filter using fuel tank sealant.

This completes the installation of the Optional Fuel Pump Noise Filter. That's it for today's work session on the RV-12 airplane.
