MIL-HDBK-525 EWIS overview: Task 2 — Task analysis for EWIS

Carina Cannon
In order to get a better understanding of wire degradation,  this is a good view of task analysis for EWIS.  This article discusses the second task “Data Analysis” in the series on EWIS Service Life Extension Program (SLEP). This is based on the new guidance developed by the USAF for the sustainment of aging aircraft […] Read more

MIL-HDBK-525 EWIS overview: Task 1 — EWIS documentation

Michael Traskos
This series on EWIS Service Life Extension Program (SLEP) risk assessment techniques discusses the implications and ideas contained in the EWIS handbook MIL-HDBK-525; an overview of the handbook objectives was covered in the MIL-HDBK-525 Overview for Service Life Extension article. Each article in this series will review a task or a subtask within the EWIS […] Read more

MIL-HDBK-525 overview for service life extension

Michael Traskos
The newly published Electrical Wiring Interconnect System (EWIS) Integrity Program Handbook (MIL-HDBK-525) provides a comprehensive method for assessing an aircraft’s EWIS condition for service life extension and ensuring continued airworthiness. There has not been a consistent method by which maintainers have determined the EWIS system health of their platforms, leaving each group to develop their […] Read more

Aircraft databases that impact aircraft engineers

Lectromec Team
There are a number of aircraft databases that exist on the web that can be used to survey aircraft incidents and service problems. One of these databases may have the answer to an important question from an aircraft engineer. This Lectrogram shall provide a brief summary of several of the more robust databases relevant to aircraft […] Read more
