This is the third article in this series that is looking at the individual components of Federal Aviation Administration (FAA)’s EWIS regulation 25.1707 and EWIS regulatory compliance. This is part of a series on Regulatory Compliance. If you missed the others in this series, they are listed below: Jan 20, 2014 Part I: Damage assessment […] Read more

EWIS regulatory compliance with 25.1707, Part II

January 28, 2014 Michael Traskos

This is the second article in a series on EWIS Regulatory Compliance. The series is looking at the individual components of the Federal Aviation Administration (FAA) EWIS regulations 25.1707. The first article covered section ‘a’ of the regulations. Continuing the examination of the FAA EWIS separation requirements detailed in 25.1707, this article examines the next […] Read more

Building an electrical wire testing program: Selecting tests, Part II

March 18, 2013 Michael Traskos

This article is a continuation in a series devoted to providing guidance to engineers on what should be considered when comparing different wire insulation types for a given application. It can be the basis of an electrical wire testing. Here are the previous articles: Determining the Right Wire for your Application Building a Wire Program […] Read more

Building an aircraft electrical wire testing program: Selecting tests, Part I

February 7, 2013 Michael Traskos

This article, which focuses on test selection, is a continuation of a discussion on wire selection that was started in the Determining the Right Wire for your Application article. The series could be used as a basis for understanding electrical wire testing. A quick scan of the wire tests on WireFacts.com demonstrates that there are […] Read more

Correct aircraft wire selection for your application

January 17, 2013 Michael Traskos

Wire selection for a particular application can be a time consuming process. Selection of the right wire for the particular application to maintain device reliability and prevent a potential catastrophic failure (in the case of signal quality degradation or electrical arcing for power wires) can be difficult.In the aerospace industry, this is rather simple: there […] Read more

Guidelines for aircraft wiring: Which tests?

January 13, 2012 Michael Traskos

Aircraft wiring details are rarely found in common wire specifications. In fact, there is not a consistent set of specification tests for aerospace wiring. One wire type requires testing of the wicking properties, whereas the other does not. As an engineer, this can be unnerving at times, because it prevents a simple comparison between the […] Read more

Aircraft wire failure and incident investigation, Part II

November 23, 2011 Michael Traskos

A couple of weeks back, we wrote the Wire Failure and Incident Investigation article that reviewed some of the characteristics of wire failure and the means to detect them in a post aviation incident investigation. That article focused mostly on the conductor failure mechanisms. The three failure mechanisms that will be covered in this article […] Read more

Aircraft wire degradation and new research on red plague

November 20, 2011 Michael Traskos

We have addressed the red plague concept behind the aircraft wire degradation process in the For wire systems, there is no perfect conductor, not even a silver plated one article. However, since this issue has been spurring a new level of interest every five years, we are updating you on the new developments. To briefly […] Read more

What to look for with composite aircraft wire aging

August 13, 2011 Michael Traskos

This article continues the theme of identifying different kinds of wire aging, by describing the signs indicating when a composite wire is starting to age. Read more
