Suspected Unapproved Parts (SUP) Program
The FAA is committed to discovering and removing Suspected Unapproved Parts (SUP). The agency has extensive guidance on how suppliers and maintenance facilities can prevent them from being installed. The FAA thoroughly investigates every SUP report. If we determine a part is unapproved, we notify aircraft owners, operators, manufacturers, maintenance organizations, parts suppliers, and distributors.
