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.

Parts Manufacturer Approval (PMA) List of PMA Parts

Parts Manufacturer Approval (PMA) article listings are maintained in the FAA Dynamic Regulatory System (DRS). In DRS you may search PMAs by PMA holder, PMA article name, number, approval basis, as well as make and model on which the PMA part can be installed.

If you cannot locate the PMA data you desire, or have other questions about a Parts Manufacturer Approval, contact the Certificate Management Branch in the geographical area of the PMA article holder.
