Scott & Tanya Card RV9A build log (N4822C)

Whew, it was a full weekend of building. I continued working on the fifth point harness brackets. It turns out that the extra snap bushing holes that I punched a long time ago in the seat ribs were quite in the way of the forward brackets. I notched the brackets and left out two rivets per side to allow for the bushings. Done.

I mounted the fire extinguisher bracket on the aft member behind the flap housing. Then I worked out making a little bracket and actuator assembly for the AOA flap sensor switch. I’m very pleased with my variation on the solution. It was super easy and very effective. Luckily I had run some conduit laterally through the baggage floor ribs which made wiring the switch very simple. I also finished up wiring the flap motor and FPS system. I even temporarily installed the switch in the instrument panel and operated it from there. Woo hoo, very fun to see something operate after the first wiring work.

I don’t have any of my Grand Rapids stuff so I had to make a little paper mock up of the foot print of the air data computer for positioning of a bunch of other stuff in the upper fuselage. I next worked on a battery box for the EFIS aux battery. It is a small 5A battery. Fun with angle aluminum. I’m going to use a couple of long AN3 bolts into nutplates for hold down.

 

  

  

  

  

  

  

  

  

  

 

I got word today from Mattituck that my engine is ready to ship. Time to raid the bank account.

I got a recent order from Vans with some random stuff in it including the fire extinguisher (so I can setup the mount) and the fifth point harness (crotch strap) attach brackets. I dove into the attach brackets and got them deburred and positioned. This would really be easier done way earlier when building the center section. Oh well, it isn’t rocket science either.

I ran my first few wires. Pulled the power and signal wires for the rear nav light, strobe and elevator trim through the conduit to the rear. Hopefully this is leading up to being able to close up the rear of the fuselage with the top skins.

I contacted Mattituck to check on the status of my engine. It has been built and is waiting on the Pmags from emagair for the test run. This was expected. I’m expecting a few more weeks. That will work out well (hopefully).
