CS-ETSO, European Technical Standard Order
Section 01: Organizations & Authorities
Definition
The EASA Certification Specifications containing the European Technical Standard Orders (ETSOs), which define minimum performance standards for specified articles (components, equipment, parts). An ETSO authorization issued under Part 21 Subpart O certifies that an article meets the applicable ETSO standard. CS-ETSO indexes are largely harmonized with FAA TSOs, with the ETSO number typically corresponding to the equivalent TSO number (e.g., ETSO-C151 corresponds to TSO-C151).
