Vans Aircraft RV-12 Build, Section 22: FWD Lower Fuselage (part 4)

Reference: page 22-04, 22-05; 2 hours

I have passed the 1,000 picture mark during the construction of this RV-12. This has created a challenge as I am currently storing the pictures on Picasa. Not a real problem as I just needed to set up a new file folder, however the day is coming when I will run out of room on Picasa. But that day is ot today so let's get to it!

Note: The fuel flow meter provided will be one of two types. Page 28-05 of the RV-12 plans depict both types. Determine the fuel flow meter provided with the kit and use the applicable hardware.

Builder's note: My kit came with the FT-60 Fuel Flow Meter so that is what the mount below is built to match. Some of the steps out of sequence as can be seen by the primer shown in the pictures.

Step 1: Install nutplates to the VA-188 FLO_SCAN Mount Bracket per the call-outs in Figure 1 if using a Flo-Scan Fuel Meter or Figure 2 is using a FT-60 Fuel Flow Meter. These figures are on page 22-04 of the RV-12 plan by Van's Aircraft.

Step 2: Cleco the FLO-SCAN Mount Bracket to the Fwd Fuse Floor Skin. Final-Drill #30 the four attach holes. Remove the bracket and deburr both parts.

Step 3: Rivet the FLO_SCAN Mount Bracket to the Fwd Fuse Floor Skin per the call-outs in Figure 2 on page 22-04 of the RV-12 plans. Manufactured Head on the Bottom of Fuselage

This completes page 22-04.

Reference page 22-05.

Caution: Do not rivet the upper row of holes in the F-1271-L & -R Fwd Fuse Corner Skins that will later attach to the F-1270-L & -R Fuselage Side Skins

Step 1: Cleco then rivet the Forward Lower Fuse Assembly to the Mid Fuse and Bottom Skin Assembly as shown in Figure 1 & 2 of the RV-12 plans on page 22-05. The skins from the Fwd Lower Fuse lie over outside of the skins on the Mid Fuse and Bottom Assembly.

In the picture below I'm not saying "the RV-12 is number one", which of course is a given. But rather I found by starting with the bottom rivet and working upwards made the riveting job much easier.

This completes both page 22-05 and section 22 of the RV-12 airplane.
