What is MagCheck?

MagCheck LLC has developed a safety-critical aviation monitoring system that provides real-time notification of magneto failure in single-engine piston aircraft and select piston-powered rotorcraft. The product addresses a long-standing gap in general aviation safety by detecting ignition failures that are often intermittent, silent, or only recognized after power degradation.

The system is designed as a non-intrusive, retrofit-friendly solution that enhances pilot situational awareness without altering engine operation or increasing pilot workload.

​

Our product was developed after experiencing a Magneto failure during a routine run-up — a failure that most likely occurred on the previous flight without any indication. This raised an important question: why are we still verifying Magneto operation by turning them off? We don’t test a fuel valve by shutting it off, and in flight, troubleshooting a Magneto problem leaves a 50/50 chance of accidentally disabling the good one.

 

After finding no existing solution that allowed Magnetos to be tested without switching them off, MagCheck was created to provide a safer, more reliable method. MagCheck continuously monitors both Magnetos and immediately provides visual and audible alerts if either one fails, clearly identifying the affected unit.

MagCheck is designed to enhance pilot awareness, improve safety, and modernize the way Magneto health is monitored

 

The system requires no special training and operates automatically in the background. On power-up, MagCheck displays a red indicator and tone for each Magneto, turning green as each one comes online. During run-up, switching Magnetos triggers the corresponding indicator so pilots can instantly confirm proper operation. The system also performs a self-test during every run-up and integrates seamlessly into existing procedures — no checklist changes required.

 

MagCheck is FAA NORSEE (Non-Required Safety Enhancing Equipment) approved for all piston Aircraft and Helicopters.
