Continued Airworthiness and overhaul information is contained in thenmanufacturer's maintenance (overhaul) manual.

In the case of magnetos it is specific to the magneto manufacturer, and in some cases, to the aircraft. For example, some Slick Magnetos on some Lycoming IO-540 engines have 200 hour impulse coupling inspection requirements mandated by the manufacturer and an airworthiness directive

Generically, there is a 500 hour inspection requirement for both Bendix and Slick magnetos and a overhaul at engine TBO.
