RV-12 Tailcone (Part 8)

Reference: page 10-8; 1 hour

Another short day of working on the RV-12 aircraft. One thing on the static system is to make sure the tee on the left side is not below the static port on that side. Otherwise water can get in the system. Had this happen on our Mooney and it was an expensive fix!

Step 6: Follow the 'Installing the Static Air System instructions to install the left and right side static sources into the F-1280-L & -R Left and Right Side Skins in the locations called out.

Step 7: Install the end of the 1/8 ID clear Plastic Tube over the right static source. Route the 1/8 ID Clear Plastic Tube along the inside flange of the F-1208 frame. Follow the inside flange of the F-1208 Frame to the left side. Secure the tube with plastic tie wraps through the holes along the flange. Install the loose end of the 1/8 ID Clear Plastic tube to the plastic tee. Position the plastic tee at the same height as the J-stiffener located directly above the static source. Install the end of a separate piece of 1/8/ ID Clear Plastic Tube to the left static source and the other end of that tube to the plastic tee.



Step 8: Install a 1/4 inch long piece of 1/8 ID Clear Plastic Tube to the remaining leg of the plastic tee. Builder's note: I found it easier to install this before installing the other section of 1/8 tube. Connect one end of the PT 1/4 OD Polypropylene tube to that same leg of the plastic tee. Route the polypropylene tube down the inboard flange of the frame, then to the J-stiffener of the F-1281-L Lower Left Skin as shown in plans. Route the tube inside the J-stiffener 'hook' of the lower skin with the WH-P30 shown on page 10-08. Coil the remainder of the tube and secure the coil to the inside of the lower left skin with tape or string.


This completes page 10-08.
