Aircraft Service Life Extension Program (SLEP)

Understanding Life Prediction Technology

Michael Traskos
To understand the basis for wire life prediction, there are parts of the process that must be understood from a fundamental perspective and how these fundamentals are applied to the long-term reliability and life prediction of the components. This article will cover some of these basics, the research that has gone into this field, and how it is used as part of EWIS sustainment and service life extension projects. Read more

Aging Aircraft Wire

Michael Traskos
Aging aircraft wiring is a problem affecting the entire aviation industry. Lectromec’s evaluation of the 2016 service difficulty reports found that aircraft over 25 years old were more than two times likely to suffer problems with their wiring system. There are tools and analyses to get ahead of these issues. Read more

When to Pull the Component – End of EWIS Component Service Life

Michael Traskos
What is the end of life for a wire, cable, connector, or any Electrical Wiring Interconnect System (EWIS) component? This is a straightforward question that should have a straightforward answer, but often, this is an unanswered question. Regulatory guidance such as Fuel Tank Ignition Source Prevention Guidelines from the FAA think of wiring as something […] Read more

Getting the Most Value from Wire System Degradation Assessments

Michael Traskos
Task four of military handbook MIL-HDBK-525 (also incorporated into the mechanical subsystems integrity program standard MIL-STD-1798) outlines a set of considerations and procedures for the assessment of an aircraft electrical system specifically for the service life extension program (SLEP). The important factor is to ensure that resources are not wasted on this effort and that […] Read more

EWIS SLEP Reassessment

Michael Traskos
In past articles, we have talked about a comprehensive assessment of Electrical Wire Interconnected System (EWIS) Service Life Extension Program (SLEP) that is possible with following the guidance laid out in MIL-HDBK-525. One of the areas that Lectromec did not cover thoroughly in these articles is what to do five or ten years after the […] Read more

What is an aircraft wire Service Life Extension Program (SLEP)?

Lectromec Team
Over the years, the Lectromec website has received hundreds of thousands of visits. Often the topic of interest deals with Aircraft Wire Service Life Extension Programs. Because of this popularity, the Lectromec Podcast sat down with the president of Lectromec, Michael Traskos, to talk about Service Life Extension, or SLEP. During the interview Michael starts […] Read more
