The impulse coupling is arguably one of the most stressed components in your magneto, and it is important to have regular inspections done in order to avoid a situation like this.
Complete or even partial failures impact engine starting, magneto operation, and can introduce foreign fragments that cause internal engine damage.
Complying with the 500hr interval inspections required on both Champion and Bendix magnetos will help catch any impulse coupling issues before they become catastrophic failures.
