International cybersecurity coordination for aviation covers: (a) EASA Part-IS (EU Commission Implementing Regulation 2023/203) - the EU equivalent of FAA aviation cybersecurity framework, mandatory for EU-registered aircraft + operators + service providers + maintenance organisations + design organisations + production organisations; (b) FAA-EASA Bilateral Aviation Safety Agreement (BASA) + Implementation Procedures for Airworthiness covering mutual cybersecurity acceptance for type certificate cross-validation; (c) ICAO Annex 17 (Aviation Security / AVSEC) which historically addresses physical aviation security + has expanded into cybersecurity (since 2018 amendments); (d) ICAO Aviation Cybersecurity Strategy (2019); (e) ICAO Cybersecurity Action Plan (2022 update + ongoing); (f) coordination with allied nations on aviation cybersecurity standards including Five Eyes + EU Member States + Japan + South Korea + Australia + New Zealand. International coordination is critical because aircraft + operators routinely operate across multiple jurisdictions + a fragmented cybersecurity regime would create competitive + safety + supply-chain inefficiencies.
