The objective of this Notice of Proposed Amendment (NPA) is to ensure that the Acceptable Means of Compliance (AMC) and Guidance Material (GM) to CS-23 reflect the latest technological developments and certification practices for normal-category aeroplanes.
Specifically, this NPA proposes to incorporate updated consensus standards developed by ASTM International. These standards, established through the ASTM F44 committee, provide state-of-the-art methods for demonstrating compliance with CS-23 requirements.
EASA has reviewed the revised standards and, where appropriate, included them in AMC1 to CS-23. The proposed regulatory material is expected to support global harmonisation, ensure consistency with performance-based regulations, and promote innovation by maintaining a regularly updated set of compliance means.
