New aeronautical aerospace component designs strives the manufacturers to use new shaping processes which permit to add specific features such as stiffeners, often leading to weight or lead time saving. Additive Manufacturing (AM) processes are identified to as a very strong potential candidate, such as Electron Beam Melting (EBM) or Sintering Laser Melting (SLM). They provide many advantages in comparison with conventional processes to the aerospace market for using them in component manufacturing (OEM or Tier 1) or in component repairing (MRO). But airworthiness and air transport safety must be guaranteed. In this market, issues as design, manufacturing and maintenance are quite regulated. New certification procedures and approaches must be considered and developed for including AM in the aerospace market. The AM certification process in aircraft market becomes a huge effort in terms of human resources, cost and time. In the certification process a close relationship between the applicant and the corresponding aviation regulatory authority (ARA) be established in order to optimise the certification process. The ARA and Industry are committed to improving the effectiveness and efficiency of the product certification process by establishing up-front a clear understanding of the needs and expectations of both parties in the product certification process. Reducing the cycle time to certify products, while ensuring regulatory compliance will require earlier involvement of ARA and Applicants in project planning, open and constructive communication, and safety focused project management. Early involvement helps to identify and resolve the certification basis more efficiently, e.g. means of compliance, special conditions, etc. This process will result in a more effective use of ARA and Industry resources, particularly through the use of ARA Designees with oversight focused on critical safety areas. Also, by reducing the time and cost of product certification, safety enhancements through new technology and design innovation can be more rapidly integrated into aviation products.
