Corrosion Prevention and AC 43-206 Part 2

In this article, we look at procedures identified in AC 43-206 for the cleaning of avionics equipment to remove and prevent corrosive deposits. After initial inspection and identification of corrosion in avionics systems, the next logical step is to perform cleaning procedures to reduce/eliminate the risks from corrosion. Inspection and cleaning procedures should be performed on a regularly scheduled basis, as well as immediately following any situation(s) in which the avionics components are exposed to probable sources of contamination (weather, salt spray, spilled fluid(s), cleaners used for nearby systems, and any remnants from repair).

Corrosion Prevention and AC 43-206

This article will discuss inspection methods for evidence of corrosion on aircraft and aircraft systems; a future article will address some of the maintenance and cleaning guidance offered by AC 43-206. Read more

IEC 60851-5 Winding Wires – Electrical Property Test Methods

Winding wires, or magnet wires, are the wires used to construct coils in electronic components (transformers, relays, etc.) that generate the component’s magnetic field. These wires are primarily composed of a copper or aluminum conductor with a very thin layer of insulation. The insulation layer is as thin as possible to keep the wire cross-section small making it possible to squeeze the highest number of windings in the motor. Whereas most electrical wires are cylindrical, winding wires often have a rectangular cross-section profile; this allows for maximum cross-section during winding, thus reducing potential losses.

Heat Shrink Tubing Tests

Heat shrink tubing is a very commonly used component in Electrical Wiring Integration Systems (EWIS). Just as with any other component of an aircraft wiring system, heat shrink tubing must withstand extensive severe testing before being approved for use. This article reviews select standards and methods for heat shrink tubing testing. Read more

Heat Shrink Tubing Flammability Tests

As is the case with many components in electrical wiring, one of the most important properties of heat shrink tubing is its resistance to fire. Take a look at several methods used to determine and categorize the flame-resistant properties of heat shrink insulation tubing. Read more

AIR7502 and Future Implications for Aviation

The AIR7502 defines voltage levels for HV aircraft and components. The extent to which AIR7502 is incorporated into the aerospace industry remains unsure, but the implications of the document are worth considering even before the document’s use is determined. Read more

ICA Guidance for HIRF and Lightning Protection

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

Top 5 Articles of 2021

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

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.
