5.7 Aircraft Wiring
We do not recommend or approve of anything other than wiring that is approved for certified
aircraft. If a previous installation used PVC or telephone wire it is
not acceptable to re-use
those harnesses for this installation.
Generally, no PVC wiring or off-the-shelf phone cords meet the requirements found in AC43.13-
1B/2A. Wiring must be strong enough and have the durability to withstand normal operations.
A minimum of 19 strands is required and must be made of a material that does not have
excessive line loss and must be on the Qualified Products List.
Emerging Lifesaving Technologies requires the wires meet the current FAA requirements. We
require that the wire be Mil Spec 22759/24 or MIL-W-16878, or M27500 or their commercial
equivalent. Either 24 or 22ga is acceptable. An eight (8)-conductor bundled wire of Mil Spec
22759/18-24 is also acceptable.
All aircraft wiring must adhere to the aircraft manufacturer’s instructions, current FAA rules and
regulations, and any advisory circulars that may be applicable, e.g. AC 43.13
It is important that anyone changing or altering an aircraft’s electrical system be appropriately
trained and certified to do those functions.
CAUTION:
MISTAKES IN INSTALLATION MIGHT KEEP
HELP FROM EVEN KNOWING YOU ARE IN TROUBLE
