Confidence in Every Flight
Your Expert Resource for in flight Magneto Checks
Magneto's don’t fail on the ground — they failed on your last flight, you just didn’t know it.
MagCheck continuously monitors the high-voltage output of each Magneto and delivers instant visual and audio alerts the moment a failure occurs.
Unlike traditional pre-flight checks that capture only a single moment in time, MagCheck watches your Magneto's every second of every flight.
About Us
Who We Are
MagCheck 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.
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 designed to enhance pilot awareness, improve safety, and modernize the way Magneto health is monitored
.MagCheck is FAA NORSEE (Non-Required Safety Enhancing Equipment) approved for all piston Aircraft and Helicopters.
Inflight Magneto check goes wrong when key break off in ignition
By NTSB August 16, 2024
The pilot, seated in the left seat, said that the instructor pilot, seated in the right seat, asked her to perform a magneto check inflight.
During the magneto check, she inadvertently turned the ignition key to the off position, resulting in a total loss of engine power to the Cessna 172.
As she turned the key to restart the engine, the head of the ignition key broke off.
The instructor pilot attempted to move the ignition key but was also unsuccessful.
The instructor pilot took the controls and performed an emergency landing onto a school football field near Gates Mills, Ohio.
The airplane landed hard and sustained substantial damage to the firewall, both wings, engine mount and fuselage. Both pilots sustained injuries in the crash.
Probable Cause: The instructor pilot’s decision to perform an inflight magneto check with no suitable area to land. Contributing to the accident was the pilot’s failure to correctly perform a magneto check that resulted in a total loss of engine power.
