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 EWIS failure trends

April 1, 2015 Michael Traskos

The process for identifying an EWIS problem on an aircraft often follows these steps: At some point during aircraft operation a system malfunctions and the pilot reports the malfunction. Maintenance starts by replacing the system component. Depending on schedule and criticality, the maintenance action is scheduled. Often, the first action to be taken is the […] Read more

EWIS SLEP: 5 days in the desert

December 5, 2014 Michael Traskos

As part of a project with the US Navy, Lectromec staff was in Tucson for one week supporting a service life extension program (SLEP). We all know that aircraft are designed for a given number of flight hours. One question that an asset manager may ask is if the aircraft has reached this threshold, is it still able to accomplish its mission? In the terms of commercial aircraft, can the asset deliver passengers safely and reliably? It is only reasonable that an assessment should be performed to determine what changes might be necessary to accomplish this. Read more

EWIS Risk Assessment for Service Life Extension Programs (SLEP)

Summary of Lectromec’s EWIS SLEP services Decrease maintenance load, achieve compliance with requirements, and have a clear data-backed path for wiring system sustainment; these are achievable. As evidence of this, Lectromec has prepared a case study detailing a segment of our process and how it helped a fleet avoid millions of dollars of unnecessary wiring […] Read more

New Platform Services The creation of a new aircraft’s Electrical Wire Interconnection System (EWIS) is a big challenge: design, assessment, component selection, zonal impact on component reliability, risk mitigation, and finally installation. Lectromec has the capabilities both in the lab and from an engineering standpoint to ease your EWIS design process. Find out more Existing […] Read more

The “Big 3” aircraft wire system degradation assessment options

April 9, 2014 Michael Traskos

If you have concerns about aircraft wire system degradation and need to assess the condition of an aircraft’s wire system, there are several options. For those looking for opens and shorts type faults, HiPot and/or Time Domain Relectometer (TDR) equipment are great options. To determine the impact of wire problems with the fleet, maintenance logs […] Read more

Commonalities between EWIS and structured risk assessments for life extension programs

August 31, 2011 Michael Traskos

One of the criticisms of the EWIS risk assessment field is that it is an inexact science. Another is that no real value is achieved from performing an EWIS risk assessment. This article reviews these criticisms and shows how the EWIS risk assessment process follows accepted industry standards for aircraft assessment. The value of these […] Read more

Physical and functional EWIS issues included in Rule 25.1709

January 1, 2008 Lectromec Team

The recent set of FAA rules deal with physical and functional EWIS issues. The rules were released for the Enhanced Airworthiness Program for Airplane Systems/Fuel Tank Safety (EAPAS/FTS) places new requirements on system safety and certification of aircraft Electrical Wiring Interconnection Systems (EWIS). These new rules were effective as of December 2007. They are the culmination […] Read more
