16. Abstract
Original aircraft manufacturers have designed and built aircraft with various wire types due to the improvement of technology,
materials, and processing of wire. New aircraft may have multiple wire types in the same aircraft to meet various environmental
zone requirements. Wiring sections may be modified or rewired with the same wire that was originally installed in the aircraft or
with a newer, more advanced wire, thus mixing wire types in bundles. Little data has been generated and published indicating
whether mixing wire types creates problems with the long-term integrity of the electrical wiring. The objective of this research
was to assess past and current guidelines, to review prior research and test data, and to perform additional testing to determine the
effects of mixed wire types in electrical wiring interconnection systems in aged aircraft. Where applicable, develop
recommendations regarding the mixing of wire types in aircraft applications.
