Have we Reached the End of Aging Aircraft Wiring Systems? – Part II

At the start of the last article, the question was posed, “Is it possible that aircraft wiring reached a point where aging/degradation is a thing of the past?” In that article, four elements were identified that must be satisfied for wires/cables to be considered as age-free. The insulation and conductor aging factors were examined in the last article, and here we consider the remaining two: Design limits and random shocks. Read more

What is an EWIS Qualified Wire?

This is a question that Lectromec regularly receives. The reason for this question is that a parts-supplier or system-integrator is looking to find wires in compliance with EWIS requirements. Since there are so many ways to evaluate any component, the important question to consider is if a defined requirements list for aerospace wire exists? Here, […] Read more

Where can I get aircraft wire and cable tested?

This is a common question for aerospace engineers who are working with the Electrical Wiring Interconnect System (EWIS) as well as aerospace Maintenance Repair and Operations (MRO) professionals. Basically, if you have an EWIS component that needs to be tested, you can either test it yourself or contract with an aerospace wire testing organization. However, […] Read more
