With the few restrictions we have here in the US on homebuilt aircraft, PVC pipe can be found in many flying aircraft. for the most part (I'm sure SOMEONE will post something to the contrary) local regulations don't exist that govern what materials we build from. (Last I checked the Resin used in composite craft was pretty nasty stuff too).
If you're out to save the world (not a bad thing for any of us to do I suppose), you could look into Polyethylene pipe instead of PVC. Then again, you could also weave one from hemp grown in your own back yard if that blows your skirt up. It's all in what extreme you want to take it to. Just my two pennies worth...

Graham/Michael,
With respect, and wishing to make sure you don't tred on the toes of
officialdom, it may be prudent to check that any applicable fire
ratings for PVC usage are observed. I recall PVC burns with toxic gas
emissions. Other listers may be better aware of any local constraints.
cheers

One more comment on this "Off the wall" topic: Perhaps the most
dangerous material used in any airplane or house is polyurethane
foam. In airplanes (virtually all planes including airliners) this
foam is used in the seats. In residential buildings (and commercial
ones too) it is used in nearly all pieces of furniture that is not
just bare metal or wood or plastic. It is also used to prop up most
floor carpeting. When this material is burned it generates huge
quantities of HCN - you guessed it folks, Hydrogen Cyanide - one of
the deadliest gasses known to man. It is the cyanide that kills most
folks in fires.

PVC pipe long enough o go form the wing tip to the root and wide enough to slide wire through would be heavier than a few clamps. Pre wire the wing with clamps. Doing it that way will also allow for a bit more heat dissipation... hope you won't need that.

I used the clear safety tubing that goes over fluoresent light bulbs. It's supposed to contain the glass in the event of breakage. It's transparent, much lighter than PVC and it's cheaper, too. I found it at Home Depot.

Its really too heavy, A better choice is nylon conduit. Vans aircraft sells the stuff and its not split either...Perfect for wing wiring.

Frank,
I'm using the thin-wall PVC pipe. It weighs just under a pound for the length of each wing. I will certainly take a look at the Vans material. I dont think it's too late to change it if it will save me some weight.
Thanks

Oh yeah, the flex conduit will only be a couple of ounces.
I used conduit for the HDS but I went with snap bushings for the RV..In retrospect I really should have used conduit again.

Hello Listers:
In my '48 Bonanza, the wires in the wing to the position lights are strung through the rib lightning holes and held by small clamps, haven't jumped out of place in 58 years. Of course, being a Bonanza, the highest quality wire was used. Remember, pounds add up and I personally have never attended a "happy" weighing, I've heard legends of them, but I've never attended one.
Regards,
Randy L. Thwing, Las Vegas

All true, Randy. However, in my '49 Bonanza , Beech used the highest
quality wire AVAILABLE AT THAT TIME.
The problem is when you want to change/add to the wiring. I have
seriously considered adding wingtip strobes to my plane, but the labor and
pain of getting new wire out to the wing tips holds me back. A added
pound or two added in order to facilitate future upgrades seems to me to
be worth it.
