EAA Tech Counsel on Fuselage Work

TLDR

• Workshop organization and clean up
• Had an EAA tech counsel on fuselage work

Detail

Clean up

Since I moved the fuselage into the hangar last week, I haven’t really got a chance to organize my tools etc to their proper location. So I spent most of the day doing that and moping up the floor to keep the workspace clean.

EAA Tech Counsel

My EAA tech counselor Jason visited my hangar in the afternoon to check out my work. And I took the opportunity to ask a bunch of questions related to AN fittings, avionics and wiring, and some other misc issues.

Inspection on WIP fuselage and avionics

A few points:

• Tail harness - I have a wire loop near the elevator tube. That’s probably fine but would be better to secure it even more so it’s not possible to touch the tube.
• Electrical tape - don’t use it. It gets gummy over time. Cable tie and/or silicone tape are better choices.
• Wire harness - no need to wrap anti-chaffing stuff between wire and cable tie. Cable bie won’t chaff through Tefzel wires.
• AN Fitting torque - Use the “flat” method, it’s easier than finding exact torque values.
  • Hand tighten, then use wrench to add a quarter turn.
• Testing wire harness: Avionics shop should have tested it. But just in case, I can test again (continuity test) wire by wire following the wire diagram.
• Wire routing: we found a few bundles of wire not fully secured so they can have movements during flight. Suggestion is to use cable tie to fix them to something rigid.
• Rudder cable clearance to surroundings: there is a very tight clearance between rudder cable to the center channel routing. I need more clearance for rudder cable. Once I can get more tension on the cable, I will be able to see where the cable goes, and then I can either put anti-chaff material, or cut away some material from the center channel routing.

Overall, I am relieved that no major issue was detected, and I think I can fix all the things pointed out!

On to the next fight!
