PMA — Parts Manufacturer Approval

Also known as: PMA

FAA-approved alternate to OEM under a PMA letter for a specified application.

Parts Manufacturer Approval (PMA) is the FAA's mechanism for approving an alternate to an OEM part for a specified application. PMA candidates are surfaced explicitly so engineering and the operator review and approve. PartsPerk never claims PMA equivalence on its own.
