A guide to Intrinsically Safe tools for MROs

intrinsically safe tools

This article explains intrinsically safe tools within an MRO environment.  It also highlights the obligations of MROs to use approved tools, and explains the potential consequences if incorrect equipment is used. What is meant by Intrinsically Safe? The aviation industry is rightly consumed with safety and accident prevention; this includes when the planes are grounded. …

What is a loop resistance test?

What is a loop resistance test?

A loop resistance test is carried out during aircraft manufacture or maintenance to check that it will be safe in the event of being struck by lightning. Why are loop resistance tests needed? Planes are struck by lightning about once a year*, based on data from the US Federal Aviation Authority (FAA). That’s surprisingly often…
