Where can I get aircraft wire and cable tested?

August 20, 2015 Michael Traskos

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

What does aircraft wire testing cost for AS22759/87?

August 12, 2015 Michael Traskos

Aerospace wiring systems are often underappreciated by other aircraft system engineers for their complexity. Aerospace wires and cables, like all aerospace components, undergo a rigorous set of qualification tests before they can be placed on an aircraft. Many in the aerospace industry want to know what the cost of aerospace wire testing is. Wire tests […] Read more

Effects of high voltage on aircraft wire connectors

August 9, 2015 Michael Traskos

One of the challenges that exist in modern aircraft design is performing more with less. That means using less space, less power, and less weight. For the most part, the technologies integrated into aircraft systems have been able to achieve these goals. Along with this push is a drive to place higher voltages on electrical […] Read more

He has worked in complex engineering projects since he got his bachelors of science in electrical engineering from Rutgers University-New Brunswick. During the discussion Fred uses his decades of experience in electronics, systems engineering, and engineering management to talk about aerospace wire system technology. […] Read more

Taking a look at aircraft wire testing and evaluation

July 15, 2015 John Gilroy

For the past thirty years, Lectromec has been a leader in the area of aerospace wire testing and evaluation. In order to provide aerospace professionals with information to increase their knowledge of this complex topic, we began creating educational materials. Accordingly, Lectromec has published almost two-hundred articles, distributes a monthly newsletter, has a podcast, and […] Read more

Aircraft wiring, nanotubes, and much more with George Slenski

June 26, 2015 John Gilroy

Today’s interview is with George Slenski, a senior electrical and electronic materials consultant. The term “subject matter expert” is thrown about casually these days. However, every now and then one encounters a person who can make the claim of deep and thorough knowledge of an area of study. George certainly fits the bill of an […] Read more

MIL-HDBK-683: Techniques for effectively analyzing data

June 23, 2015 Carina Cannon

Failure analysis and system reliability are a fundamental part of the aerospace industry. With the extremely rare exception, modern aircraft are assessed and evaluated at the component, system, and aircraft level for all manner of failure impacts. This article will give methods for effectively analyzing data and discuss the commonly accepted Failure Mode and Effects […] Read more

EWIS regulatory compliance: 25.1703, Part II

June 16, 2015 Michael Traskos

Aerospace wiring requirements like the FAA regulation §25.1703 can be difficult to comprehend in one sitting. Lectromec has taken this complex document on EWIS regulatory compliance and divided it into some logical categories. In our last podcast titled An EWIS Perspective, we examined concepts in expected life and discussed how to select components designed for […] Read more

EWIS regulatory compliance: 25.1703, Part I

June 5, 2015 Michael Traskos

Proper aircraft wire installation begins with selecting the right components. There will never be a perfect component, because there will always be tradeoffs between performance, cost, weight, and reliability. Engineering is what allows us to weigh all these factors and determine which one is the most important. The decision matrix includes requirements of the electrical […] Read more
