7 tenets of aircraft wire systems installation

There are a number of considerations when designing the installation of EWIS on aircraft wire systems. They include part selection, system integration, routing, safety and separation, regulation considerations, operational environments, maintenance, and obsolesces planning. In other words, a lot to consider. Back in 2004, Lectromec released, Ten commandments of Wire Maintenance. Below, Lectromec lists, the 7 […] Read more

Lessons learned from NASA: Wire identification, harness clamping, and more

Learning from the mistakes of the past is critical for ensuring reliability of systems created today. These lessons may be contained in industry standards documents with little or no explanation as to why the requirements were created (such as AS50881). This lack of historical knowledge and the loss of the answer to ‘why’ can leave […] Read more

Heat shrink tubing application and aircraft EWIS components

Heat shrink tubing can be found in nearly every location on aircraft and can interact with aircraft EWIS components. These materials protect wire repairs, provide additional abrasion protection, and prevent the ingress of fluids (and in a pinch, may be used as a secondary harness support when other options are not viable). Although this product […] Read more

Considerations for electrical bonding

Electrical bonding is the practice of connecting equipment cases or structure to ground to prevent electric shock. This provides a return path for any stray voltage that the case may be exposed to via component failure (e.g. wire shorted against case). The reason why proper electrical bonding techniques are so important is that it protects […] Read more
