Maintain attheplace of manufacturethetechnicaldata anddrawingsnecessaryfor the Administrator to determine whether the product and its parts conform to the type design;

(c)
Except as otherwise authorizedby the[AircraftCerti.cationDirectorateManager forthegeographic area]in whichthe manufacturerislocated,forproducts manufac-tured more than 6 months after the date of issue of the type certi.cate, establish and maintain an approved production inspection system that ensures that each product conforms to the type design and is in condition for safe operation; and

(8)
Rejected materials and parts must be segregated and identi.ed in a manner that precludes installation in the .nished product.

(9)
Materials and parts that are withheld because of departures from design data or speci.cations, and that are to be considered for installation in the .nished product, must be processed through the Materials Review Board. Those ma-terials andpartsdeterminedby theBoard tobe serviceablemustbeproperly identi.ed and reinspectedif rework orrepairisnecessary.Materialsandparts rejected by the Board must be marked and disposed of to ensure that they are not incorporated in the .nal product.
