The eight rear horizontal stabilizer hinge brackets (HS-912) were riveted onto the rear horizontal stabilizer (HS-00903-1) with AN470AD4-5 rivets using the pneumatic squeezer. I set all of these rivets with our pneumatic squeezer. There are 12 holes that do not receive rivets at this time and they were taped over (see photo above) so that I didn't accidentally rivet them today. The horizontal stabilizer rear spar doubler (HS-00906) was attached to the rear horizontal stabilizer spar (HS-00903-1) and riveted together using AN470AD4-6 rivets and two center AN426AD4-6 rivets. There are eight hinge brackets (HS-912) that were clecoed and final drilled/reamed to #30 (1/8") size and were numbered in sequence (1-8 left to right) so that they could be placed in the same position during the riveting process.Įach bracket center hole (on the tab) was final drilled to #12 (3/16") size.Įverything was then diassembled and primed with Tempo A702 green zinc phosphate primer. The two center holes are machine countersunk to receive AN426AD4-6 rivets and, in addition, the top two and bottom two holes were final drilled to #12 (3/16") to receive AN3-5A bolts and hardware to attach the center hinge bracket assembly. (They are covered with the two inner pieces of tape and will eventually have a rib attached.) ![]() There are four holes in the center of the rear horizontal stabilizer spar (HS-00903-1) and doubler (HS-00906) that aren't pre-punched so they needed to be match drilled to #30 (1/8") size. ![]() *Van's does such a great job of pre-punching the holes that usually a #30 reamer works just fine. The rear spar doubler (HS-906) is then clecoed in place onto the rear spar (HS-00903-1) and all holes common to both the doubler and rear spar are final drilled/reamed to size #30 (1/8") using the pneumatic drill. Here is the same part completely deburred around the edges. The rear horizontal spar doubler (HS-906) is next.Īs you can see the machined edges of the parts can be fairly rough. I know, Van's airplane build, Piper hat, (we used to own a Piper Cherokee). The plans start out with the construction of the rear horizontal stabilizer spar (HS-903-1) first. ![]() We are using a combination of flat and round files, scotch-brite (gray- "ultrafine" pads), and sandpaper to polish the edges and lightening holes before proceeding to the next step. These are all of the parts except for the two skins that are needed.Īs always, the process begins with the task to deburr any rough or machined edges before clecoing (using small clamps to temporarily hold pieces together) and match-drilling pre-punched holes for the final riveting process. I pulled the individual parts from the inventory that are needed to assemble the horizontal stabilizer section. The third item to work on according to the builder's plans is the Horizontal Stabilizer. Van's Aircraft does not provide a "QuickBuild" option for the empennage.īasically, the empennage kit includes everything aft of the canopy and is about half of the total fuselage. ![]() I ordered the Empennage/Tailcone Kit to build first in the RV14A project.
