ED Decision 2023/002/R Regular update of the Certification Specifications for Normal-Category Aeroplanes

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.

FAA FAA TSO-C220 Inertial GNSS-Aided Inertial System

This technical standard order (TSO) is for manufacturers applying for a TSO
authorization (TSOA) or letter of TSO design approval (LODA). In it, we (the Federal Aviation
Administration, (FAA)) tell you what minimum performance standards (MPS) your global
navigation satellite system (GNSS)-aided inertial system must meet for approval and
identification with the applicable TSO marking.

ED Decision 2023/001/R Enhancement of the safety assessment processes for rotorcraft designs’ | Regular update of the Certification Specifications for Small Rotorcraft (CS-27), and Large Rotorcraft (CS-29)

CS-27 Amendment 10 and CS-29 Amendment 11

The objectives of this Decision are to:

  • provide proportionate and cost-efficient rules in the field of the safety assessment provisions for equipment, systems and installations for rotorcraft that also maintain an overall high level of safety;
  • reflect the state of the art of small and large rotorcraft certification based on experience gathered from in-service occurrences and certification projects.

To achieve these objectives, this Decision amends the Certification Specifications and Acceptable Means of Compliance for Small Rotorcraft (CS-27) and the Certification Specifications and Acceptable Means of Compliance for Large Rotorcraft (CS-29) to introduce:

  • amendments to the CSs related to the safety assessment of equipment, systems, and installations along with AMC that introduces proportionality into the safety objectives for small CS-27 rotorcraft;
  • certification provisions and guidance material for which sufficient experience has been gained through certification (e.g. they were included in Certification Memoranda, equivalent safety findings, special conditions) or that were necessary to address Safety Recommendations.

The amendments are expected to:

  • provide greater proportionality for the safety objectives for small CS-27 rotorcraft, thereby also promoting the installation of equipment and technology that could improve safety;
  • increase the harmonisation of the EASA safety assessment provisions for rotorcraft contained in CS 27.1309 and CS 29.1309 with other EASA CSs (and SCs) and with their FAA equivalents;
  • address safety concerns that have been identified, and increase the utility and relevance CS-27 and CS-29.
