Why are MTCS certificates valid for three years? Because things change. Safety critical activities, legislation and maintenance procedures can all move on in that time, so revalidation makes sure your competence stays current. You'll be notified by automated email as your certificate nears its expiry date, and depending on how you were originally certified, you'll either redo your ICA or submit evidence like witness statements and appraisals for GA revalidation.
