ED Decision 2023/002/R

Regular update of the Certification Specifications for Normal-Category Aeroplanes

CS-23 Amendment 6 and AMC & GM to CS-23 Issue 4

The objective of this Decision is to provide for state-of-the-art means of compliance with the Certification Specifications for Normal-Category Aeroplanes (CS-23).

This Decision amends 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 with 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 Decision also introduces some additional changes to CS-23, as well as to the AMC & GM to CS 23.

This Decision is expected to improve efficiency whilst also maintaining a high level of safety.
