Our PMA Testing Services
ATS performs PMA testing services for aviation products to support various manufacturers’ PMA applications submitted to the Federal Aviation Administration (FAA). Such test results act as supporting documentation for PMA or are needed by clients in the aerospace industry requiring to verify their parts meet the latest Aerospace Material Specifications (AMS).
Industry Regulations
The Code of Federal Regulations requires any company manufacturing replacement parts for the aviation industry to go through a rigorous process and obtain a Parts Manufacturer Approval (PMA) from the FAA. This usually involves reverse engineering, where various techniques that are appropriate to the part’s complexity are utilized. Dimensional inspection and material testing are typically performed to characterize and compare the proposed replacement to the original part.
Testing frequently involves determining each component’s chemical composition, properties (ultimate, yield and fatigue strength, heat treat condition, hardness, grain structure), method of manufacture (casting, forging, wrought material, etc.), and presence of special surface treatments (coatings, platings, nitriding, carburizing, shot peening, etc.). Additional substantiating information may also be needed to show equivalency between the original and PMA parts.
