How MROs can stay electrically sharp during autumn (or fall, if you insist)
The days are shorter, hangars are busier, and every aircraft that’s been basking in the summer sun now needs a thorough once-over before the cold sets in. During this critical autumn period, MROs require reliable, efficient, and precise testing systems to ensure that aircraft are inspected, repaired, and certified to the highest standards.
Whether you call it autumn (as we do) or fall (we’ll allow it), it’s the season when aircraft electrical systems deserve extra attention. This article explains how MK Test Systems keeps maintenance teams ahead of the curve.
1. Rock-Solid Bond Testing
Corrosion, vibration and sudden temperature swings can all loosen airframe bonds. That’s bad news for lightning protection and EMI shielding. Our ExLRT and BLTU4 portable bond testers let you check every critical joint with micro-ohm accuracy—quickly, safely and without fuss. Your aircraft stays electrically bonded from nose to tail.
2. Loop Resistance That Leaves Nothing to Chance
Low-resistance connections can mask potential voltage drops or overheating. MK’s loop resistance testers pinpoint issues down to the tiniest micro-ohm. A quick sweep now means fewer “mystery faults” later—saving troubleshooting time when the winter schedule is tight.
3. Automeg: Automated High-Volume Wiring Integrity
When you’ve got a queue of aircraft waiting for electrical checks, Automeg should be your go-to. It automates continuity and insulation testing across complex harnesses, rapidly switching between circuits and producing clear pass/fail reports. Think of it as the extra pair of hands every MRO wishes they had when the hangar is full.
4. Engine Test Systems for Post-Summer Overhauls
Engines work hardest in hot weather, so autumn is prime time for inspections and test runs. Our engine test solutions combine bespoke interfaces with proven MK hardware to validate sensors, actuators and control wiring—before a small summer fault becomes a big winter headache.
5. Integrated Data, Effortless Compliance
With MKAT software, every bond, loop and engine test result is logged automatically. Need to demonstrate EWIS compliance or prep for an audit? One click, full traceability. Your QA team will thank you, but there’s no need to thank us (although a quick testimonial won’t hurt!)
6. Fast Turnarounds with Portable, User-Friendly Tools
Seasonal checks are all about speed and reliability. Our lightweight, rugged testers and intuitive software mean less time setting up and more time getting aircraft back in service. Because no one wants a “deferred due to tooling” note in the logbook.
7. Support That Travels Well
From calibration reminders to on-site training, MK’s support engineers are ready to jump in—whether you’re in Manchester, Mumbai or Miami. A quick call can have you up and running, even when the weather (and the schedule) isn’t on your side.
8. Smarter Preventive Maintenance
During autumn, damp air and rapid temperature swings can accelerate insulation breakdown. By collating and reviewing data over time, MK’s systems, tools, and software help you spot trends—highlighting connectors or harness sections that may fail before your next heavy check. Think of it as predictive maintenance without the guesswork: a data-driven way to prioritise inspections and keep your fleet flight-ready all winter.
Be Ready for Whatever the Season Brings
Whether you call it autumn or fall, the goal remains the same for all MROs: aircraft with rock-solid electrical integrity and teams who can tick every compliance box without breaking a sweat.
