Purpose of This Order.

This order prescribes the responsibilities and procedures for approving replacement and modification parts for installation on type-certificated products. It applies to Federal Aviation Administration (FAA) aircraft certification personnel and organizational designees under Organization Designation Authorizations (ODA) who implement the approval process required by Title 14 of the Code of Federal Regulations (14 CFR). We define the procedures that FAA personnel follow when issuing a parts manufacturer approval (PMA) under 14 CFR § 21.303. We also explain how an applicant applies for a PMA and describe the role of a designated engineering representative (DER) in the PMA process. FAA Order 8120.2, Production Approval and Certificate Management Procedures, contains the guidance for evaluation, approval, and certificate management for the production activities of manufacturers and their suppliers who produce parts under PMA.
