hi all,

  any recommendations for ways/ materials to attach the wiring in a wing to the wing structure that will last as long as the covering?wire ties seems like a natural but will they last 20 yrs?

  any comments would be appreciated.

The only wire I have in my wings are the shielded and insulated wires  

for strobes and position lights. I ran them through the rear spar  

tube where they just lay...hopefully content to live out their lives  

without chaffing....fingers crossed.

I ran mine down the rear spar.  If there is any problems I can just tie on a new piece and pull it through.  However  I have had no issues in over 200 hours

Coraseal won’t cut your hands if you have to reach inside the wing through an inspection port.  There are also padded Adel clamps. But for small planes that overkill and heavy.

I did the same thing with a length of heat shirnk where it enters and exits 

the spars.  900 hours in nine years.

i am building a wood wing and need a way to fasten the wire to the wood structure. noel, what is coraseal? where can i get it ? small plastic wire ties would work but i dont know about their life expectancy.

Adel clamps and lacing tapes.  Here's the tapes at aircraft spruce, includes Koroseal.

http://aircraftspruce.com/search/search.php?query=11-02012&searchsubmit=Search&search=1



AC 43.13-1b has good instructions and pictures of attaching the wire with "Offical" wrapping and knots along with the adel clamps.  Electrical is Chapter 11.  Wiring is in the "environmental section (section 9)  It starts on page 11-51 and the lacing techniques start on page 11-61.  Here's chapter 11.  http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgAdvisoryCircular.nsf/0/99c827db9baac81b86256b4500596c4e/$FILE/Chapter%2011.pdf

Bob,



I think we were unaware of your wing when we all gave our advice.  I 

recently strung the wires for trim and aft position lights up the fuselage. 

I used wire lacing tape spaced about every three inches along the stringer. 

It can also be used where there is no attachment to a structure to bind the 

bundle together for strength.  Do a google search on lacing tape.  There are 

numerous sources.  I used a "clove hitch" knot with a square knot to secure 

it.  The material is very light, wax coated so the knots don't tend to 

loosen while working on them and will last forever.



I drilled small holes in the stringer every nine inches or so.  This way, I 

could attach the wire without the wrap creating a lump under the fabric.  I 

don't think I would be drilling any holes in a wing structure, though.  If 

there aren't internal structures you can tie to, you might try what the 

Lancair guy did stringing his wiring.  he got those flat adhesive backed zip 

tie attachments available at Home Depot, etc.  He ground off the adhesive, 

drilled several holes through them for a mechanical lock and glued them to 

the fuselage or wing skin with structural adhesive, then used the lacing 

tape.  Not as light as lacing tape alone, but strong and long lasting

When I was designing / building boats and masts, we never fixed wires 

or hoses to structure in such a way that it would be difficult to 

replace later. There are several techniques available to minimize 

slop while still leaving the installations replaceable.



1. For straight runs you can run a tension wire to which the 

electrical wire or hoses are affixed at intervals. They are attached 

so they will not translate, but will slide. That way new wires can be 

slid on while the old is slid off. This would work well in either 

wing spar of a Kitfox wing.



2. For crooked runs we often used conduit, which restricts lateral 

movement while allowing replacement.



3. If you are careful you can use bulls-eyes at intervals, but you 

have to be really careful that things don't get hung up when pulling 

new hardware. The eyes have to be placed so the pulled hardware runs 

naturally from one to the next. You also have to be careful that the 

bulls-eyes won't chafe through the wire or hose over time.

i think the lacing tape  is just what i need. i have plenty of ''geodetics'' in the ribs to attach to. thanks to all who helped on this one. bob noffs

My bad, it’s called Koroseal Lacing… something like an elastic tie wrap. I think it’s available from Leavens In Canada or Aviall south of the 49th.  It can be used to protect parts to bind wires to structure.  It’s a bit on the expensive side for bundling wires…  For that I like wax cord.  Someone said dental floss would work as well for bundling and I think they’re right.  Properly used it looks a lot better then nylon and there is no chance of the stuff ever rubbing through insulation on a wire.

A  diameter just, large enough for your wiring, of plastic tubing from your  local hardware store will make a good conduit for your wiring.  Secure it  to the wood structure with a few wraps of rib lacing cord.  Doesn't add  much weight but does add a lot of protection for the wiring.
