The second step in the application process is to apply to the FAA Manufacturing Inspection Divisional Office (MIDO) to obtain approval of the manufacturing quality assurance system (known as production approval). Production approval will be granted when the FAA is satisfied that the system will not permit parts to leave the system until the parts have been verified to meet the requirements of the approved design, and the system otherwise meets the requirements of the FAA quality system regulations. A Production Approval Holder (PAH) will typically already have satisfied this requirement before PMA application is made.
