Title: 10-22 - Static System
Initial Prep (Trim, Cut, Shape, and Drill) 8/1/2021 – 0.3 hours I decided to purchase an aftermarket static port system for my RV-14A. The static ports supplied by Van's with the empennage kit are SD-42-BLSF blind rivets that are set in the empennage side skins and then have the mandrels driven out to make them hollow. The rivet/static ports are connected to a piece of 1/8” ID tubing with RTV sealant, which is then upsized to 1/4" OD tubing to run forward to the avionics. The static system that I purchased from Steinair comes with two 6061-T6 aluminum and clear anodized static ports from showplanes.com (p/n SP-01) that are installed with nuts and lock washers. The ports connect directly to the 1/4" OD tubing supplied with the system, and do not require any intermediate sized tubing. The result is a much simpler and cleaner system (my opinion). The static kit I purchased also includes the pitot and AoA lines to connect the pitot tube and ADAHRS, several push-on connectors for the tubing, and a tubing cutter. The first step to install the static system was to upsize the static port hole in the empennage side skin to 1/4". I then inserted the static ports into the 1/4" holes and lightly attached the lock washer and nut to temporarily hold them in place. I plan to remove them when I prime and paint the airplane. I think I'll also use some silicon to seal the hole from the weather when I tighten down the static port nuts. [Step Drill] Assemble 8/1/2021 – 1.0 hours I used the 1/4" OD tubing supplied by Van's to fabricate the static system harness that routes from each static port and around the top of the F-01407 bulkhead. I installed 14 4-inch zip ties to hold the static line in place while I test-fit the harness to the static ports. Both the 40” line to the right port and the 4 1/2" line to the left port were a little long, so I trimmed and test-fit until I got the length I needed. I took roughly 1/4" off the right-side line and 1/2" off the left-side line. If the lines are too long, they will kink and potentially restrict airflow when they are curved to fit the static port and harness fittings. The final step was to route the 20' tube along the bulkhead and bellcrank ribs. The diagrams for this step do not show any zip ties for the 20' tube, but you have to remember that the instructions had the aft wire harness from step 10-24 installed early including its zip ties. The figures on 10-24 and 10-25 appear to have the static line bundled with the aft wire harness in the same zip ties. I left all of the zip ties associated with the aft wire harness loose since the plans say more things are coming. [Plastic Tubing Cutter, Ruler, Scissors]
