ExLRT vs LRT: Weight Matters

weight

Part one in our Loop Resistance Tester comparison series looks at the difference in the size & weight of the only two tools approved by The Boeing Company – the legacy ‘yellow box’ LRT and its newer counterpart, the ExLRT. Lightening the load Size matters, especially when you’re working at height or in small spaces.…

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…

ExLRT vs LRT: A full comparison

ExLRT vs LRT loop resistance tester: A full comparison

Can your business afford to not upgrade from the LRT? If you’re an MRO working on Boeing aircraft, then it’s likely that you have a legacy ‘yellow-box’ LRT in your facility. You might use this regularly and are used to working around well-known flaws, or you may have heard colleagues talk about them whenever loop…

Cargolux have just become the first dedicated cargo airline to select the ExLRT from MK Test Systems as their loop resistance tool. Europe’s largest all-cargo airline, Cargolux operate a fleet of Boeing 747-8 and 747-400 freighters. Their MRO hangar in Luxembourg can now carry out specified loop resistance measurements in line with Boeing’s prescribed maintenance tests…

ExLRT vs LRT: Intrinsic safety

Intrinsic safety

This article continues our series of blog posts highlighting the benefits of the ExLRT (model XLR-9703-01) compared to the LRT (model 906-10246-3).  So far, we’ve looked at the physical differences and how suitable each tool is for use in [MRO facilities].   We’ve now arrived at the critical feature – Intrinsic Safety credentials. What does Intrinsic…
