It sounds like you are talking about maintenance checks. Usually here in the states they are referred to as inspections. As far as the FAA is concerned, a holder of a Airframe & Powerplant (A&P) certificate can perform any and all maintenance and inspections, except for the annual inspection. The person that signs off an annual inspection must not only hold an A&P certificate but also have an Inspection Authorization (IA). That is all that is required. The FAA does not put type authorizations on A&P or IA certificates. It however would be a good move to ensure that the person doing the inspections is knowledgeable of the type aircraft.
