Abstract
The use of additive manufacturing (AM) has a lot of potential for manufacturing geometrically challenging parts, components, and even assemblies. To ensure the effective adoption of additive manufacturing by the aviation industry and to expedite the standardization process, a certification roadmap is essential. This study offers a thorough analysis of the issues facing the qualification and certification of additively made parts, components, and assemblies that could be used on commercial passenger air vehicles. It also provides information regarding the general standards of AM process. After outlining the principles of technical application for the AM process, the current status of the regulations, and rules created by national/international airworthiness authorities and communities are then summarized and analyzed in terms of the manufacturing of aviation-grade parts, components, and assemblies.
