Engine compartment pictures of a Van's built RV-12iS

What are the plastic tabs? I haven't seen those before. Are they a homemade thing or a stock item of some sort?

I have some concern about the throttle cable rubbing on the top of the engine mount support but I don't see a way around it.

Also, are they using an Adel clamp combo as a standoff where the throttle cable first snakes under the engine mount tube?

I also notice the pitot tube takes a different route than the plans. I actually like this one better.

I think the clamps are Airbus ABS1339.

That's obviously not true. The question is whether Stein has that much variation in wire lengths, or maybe the factory has a special request for them them to be longer?

It absolutely is true!
A different result from one airplane to another is likely related to how and where the wires are routed in other portions of the fuselage.

There are some subtle variations. For example, the placement of the blue tie wrap which shows where the harness is level with the subpanel cutout may or may not exist (not all the blue tie wraps in the instructions actually exist). When I made my comment, I was mostly looking at the GPS antenna.

Also in the images linked, some of the wiring is tied off in the firewall forward area where the instructions have it bunched and tied off in the subpanel. So, yeah, routing make a difference. So does doing things slightly different than the instructions portray.

But settle down, fellas, it's not that big of a deal.

BTW, the images helped a lot. They made me go back and doublecheck instructions and I found I didn't put the double Adel clamp on the throttle cable.

Two hours of work for that baby.

Now if I can just figure out where those plastic sleeves are from.

Interesting things I noticed:

1. Pitot tube routing - The pitot tube routing is slightly different from the instructions. I like this routing a little better. If anyone copies, be sure to note the RTV to prevent chaffing.
2. Overflow hose (FF-01220-1) routing - The instructions call to run this hose "around the right side of the Airbox". I initially tried to follow these instructions and ran this hose over the cooling hose and ignition wires, before dropping down under the engine mount. I thought there was no way this was right and immediately changed it. I believe the proper routing is under the right side of the airbox. As shown in these pictures.
3. The overflow tube for the overflow bottle (FF-00094) routing - The instructions show running this from the cap to the left of the bottle, and then under and around. The pictures show a more direct routing to the right. Mine currently matches the instructions, but I will take a closer look at this.
4. Tubing on throttle cable - The way the throttle cable has to be routed, it comes into contact with the engine mount. Placing tubing around the cable in this area seems like a good idea. I took an extra piece of the pitot tube, slit it, slipped it over the cable and secured it with zip ties on the ends of the tubing. I'll probably apply some RTV as well.
5. Safety wire through two of the exhaust springs - I'm guessing this is to contain things if one of the springs break?
6. No RTV on exhaust spring hooks - The instructions say to "Place a small amount of RTV over the spring ends". That doesn't appear to be in place in these pictures.
7. Plastic replacement for adel clamps - These look like they would be much easier to work with than adel clamps. If I make changes in the future, I'll look into switching to these clamps.
8. General wire routing - I've got the wiring ran, but not cleaned up and zip tied yet. These pictures give me a good idea of what it should look like.
9. Color preference - This one is completely personal, but I do like the red engine coloring of the limited edition better than the green.

There is when the airplanes are delivered new. The photos were taken during maintenance. Maybe the springs had just been replaced ( they look new).

Kudos to Vans AAD division on a fine example of attention to detail!

No idea of where to buy them retail, but I see batches for sale on ebay.

Google "NMC CA2030" or "NMC CA1001" or "M23190/1"
