"Just Tell me what do do next!"
During my Patrol build, I often wondered about the EAB Industry Best Standard (IBS) of the build. I appreciated Jared's flow chart with many options, but I wanted one set of directions. This morning I ran across a post on Supercub.org. Its written by a top notch electrical guy named Web. (I contracted with Web a few years ago to build my avionics harness. That was an EAB IBS decision.) Web gives his opinionated view of the Industry Best Practice for an Electrical System Installation for recovering a certificated Supercub airframe. I welcome opinonated viewpoints from a professionals. It fits "Just tell me what to do" I thought our group might appreciate Web spin on the Boot Cowl/electrical system/instrument panel assembly sequence.
EAB IBS definition: It applies only to EAB builders. An IBS is declared. The declared method is living. Builders are encouraged to question the method and improve it. So this means we debate and are not always in agreement. New insights, tools, materials will change and so will the EAB IBS method.
______________________
From my niche: Complete new airframe wire harness. Change all lights to LEDs and wire accordingly. Strip all items from instrument panel and divide them into those you will keep and those that will be donated. Decide on new instruments and then decide which new avionics you will install. Fabricate a new, blank, instrument panel and cut it to fit ONLY the instruments and avionics to be installed. Flat black on the panel. Prewire the instrument panel, as an assembly, and hang it on the airframe. Install all airframe wiring. After boot cowl is installed install/route wiring that goes forward of the firewall. Don't forget any required coax cables. All wiring needs to be installed BEFORE fabric goes on.
If anyone tries to use old wires, beat them soundly about the head and shoulders.
