Rainy Day at the Build Center

Thought that the forecast for rain might bring a sprinkle, but we are getting a heavy rain. There is something about rain in the desert that just causes all of us to pause for a moment.  Bob came in from California last night and is doing what all of us do when it rains in the desert.


Back to work for Bob, he has an airplane to wire.


The builds have been moving along with so much change that they just seems to leap forward - right before our eyes an airplane appears. Now the builds are in the final assembly, which includes the wiring.  This stage of the build just seems to take forever without any changes.

Below is a picture of the back of Al’s instrument panel…what a mess of wires.  In the middle are the wires from the panel coming through the firewall on Bob’s plane and the final picture is a look at Ron’s plane and how those unruly wires are tamed.

Taming Wires 101

Plastic ties, shrink tubing and conduit wraps are used to tame the wires into bundles and add another layer of protection.  Just need the right stuff to tame them into tidy bundles.

Wire management is a nice professional term and I think I’ll see if there are some information on this subject that I might have missed.

First, I came across this term:   "fly-by-wire" 


All "fly-by-wire" flight control systems eliminate the complexity, the fragility, and the weight of the mechanical circuit of the hydro mechanical or electromechanical flight control systems. Fly-by-wire replace those with electronic circuits. (Wikipedia)

There was a time in aviation that wires didn’t dominate! Just hadn’t thought about a time before wires.


  1. Electronic signaling of the control surfaces was first tested in the 1930s, on the Soviet Tupolev ANT-20. This replaced long runs of mechanical and hydraulic connections with electrical ones.
  2. The first non-experimental aircraft that was designed and flown (in 1958) with a fly-by-wire flight control system was the Avro Canada CF-105 Arrow.
  3. The first digital fly-by-wire fixed-wing aircraft without a mechanical backup to take to the air (in 1972) was an F-8 Crusader, which had been modified electronically by the National Aeronautics and Space Administration of the United States as a test aircraft.

All this innovation required a focus on wiring management and ongoing research and development of better materials. (Wikipedia)  


About 1980, aircraft wiring became classified as an aircraft systems. Safety issues were addressed as wire aging and failure was resulting in flight failures.   Routine checking of the wiring system or EWIS, (electrical wiring interconnection system) and wire management have become best practices for general maintenance of aircraft.


Al is busy with his “paperwork” in preparation for the inspection that will be coming soon.  He is in final assembly and paperwork is part of this stage.



It is still raining the builds are progressing and I am entertaining myself with a fall project.

Speaking of projects.  Here are some of Greg’s and Crystal’s.  Can you guess what they are doing with these:
