Life-Limiting High Voltage Parts

Michael Traskos
Life-Limited EWIS parts can be useful where high voltage conditions make component degradation rates uncertain. Though accelerated aging can offer insight to the component’s condition, further observations of high-voltage systems will be needed for accurate degradation predictions. Read more

ICA Guidance for HIRF and Lightning Protection

Laura Wishart
The advisory circular 33.4-3, issued by the FAA offers guidance for developing adequate ICA for an aircraft’s HIRF and lighting protection functions. Read more

The Longevity of High Voltage Components

Michael Traskos
What does a wire need to do in the high voltage system, and how does it need to perform? This article reviews some of the fundamental concepts involved and what needs to be done to show a wire is compliant with the vehicle’s requirements. Read more

S&T 2021 Meeting Report

Laura Wishart
A discussion covering the topics of interest presented at the FAA’s annual S&T meeting in 2021. Read more

Top 5 Articles of 2021

Laura Wishart

It was a busy year for Lectromec’s publishing team; in 2021 we published 22 articles, one brand new whitepaper, and several of our articles were picked up for redistribution. We took some time at the start of this new year to review these articles and we present here our annual round-up of Lectromec’s most popular articles from 2021.

AS23053 Dimensional Life of Heat Shrink Tubing

Laura Wishart

We are told that low humidity and cool temperatures are the best way to extend component life, but even in such conditions not all components can sit on a warehouse shelf indefinitely awaiting the day of installation. One of the more susceptible EWIS components to aging on the warehouse shelf are heat shrink tubing. Here, we examine concept of dimensional life of heat shrink tubing.

Low Temperature Bend Testing for Lunar Applications

Laura Wishart
NASA sought to evaluate wire and cable flexibility for lunar applications; specifically looking to evaluate the ease of reeling/unreeling wire and cable in lunar environments. Bend testing was performed on 35 different insulated wire and cable constructions at liquid nitrogen temperature to evaluate flexibility in extreme cold conditions. It was the intent of this effort that, “testing at the extreme cold temperature of liquid nitrogen will begin to build a database of what off-the-shelf types of wires and eventually cabling may be applicable to the lunar environment.” Read more

Risk Assessment and Small Aircraft Certification

Michael Traskos
The basic idea behind the F3230 is to limit the total number of assessments to those that are of particular concern for aircraft safety. This aligns with the change of part 23 aircraft the FAA has implemented for a more performance-based certification approach versus the detailed and prescriptive approach that the FAA used prior to 2016.

Verification and Validation

Devon Gonteski

Amidst the manufacturing process, a structured system of quality assurance is of utmost importance; implementation of a standardized evaluation system is key to ensuring that whatever is being made is up par for its certain usage. In the world of technology and manufacturing, the evaluative journey of a product from start to finish is broken up into multiple segments.
