As you can imagine, it is dangerous to operate an aircraft without performing consistent inspections on your engine parts, and your engine magneto is no exception. It is typically recommended to get a full inspection of your magneto every 500 hours. This is not only necessary for the pilot and passengers' safety, but also for the longevity of your aircraft. Exceeding 500 hours without a magneto overhaul or replacement can lead to circumstances nobody wants, such as mid-flight complications or engine failure.
However, the 500-hour recommendation doesn't mean that every magneto must be replaced with an entirely new one. After all, a magneto overhaul can be a cost-effective way to keep your engine running smooth, safe, and proper. The internal mechanisms of the magneto can be replaced with new parts, therefore making your aircraft ready for another 500 hours of flying time!
