Regular update of the Certification Specifications for Normal-Category Aeroplanes — CS-23 Amendment 6 & AMC & GM to CS-23 Issue 4

The objective of this Notice of Proposed Amendment (NPA) is to provide for state-of-the-art means of compliance to the Certification Specifications for Normal-Category Aeroplanes (CS-23).
This NPA proposes to amend CS-23 and the Acceptable Means of Compliance and Guidance Material to CS-23 (AMC & GM to CS-23) to incorporate 6 new and 23 revised consensus standards that are issued by the American Society for Testing and Materials (ASTM) International as an acceptable means of compliance to CS 23. EASA reviewed those amendments to the referenced standards that introduce state-of-the-art means of compliance, supporting global standardisation and harmonisation. In some cases, EASA complemented the incorporated ASTM consensus standards by remarks, to identify differences or limitations due to EASA’s interpretation of these standards.
This NPA also proposes to introduce some additional changes to CS-23, as well as to the AMC & GM to CS 23.
