The Federal Aviation Administration (FAA) has proposed new cybersecurity regulations for transport category airplanes, engines, and propellers.
This initiative aims to address the growing threats posed by unauthorized electronic interactions, ensuring the safety and integrity of modern aircraft systems.
The proposed rules, detailed in a recent Notice of Proposed Rulemaking, are open for public comment and represent a crucial step in harmonizing U.S. aviation standards with international regulations.
Understanding the Proposed Regulations
The FAA’s proposed regulations focus on enhancing the cybersecurity of aircraft systems by introducing new design standards.
These standards will require applicants seeking design approval for transport category airplanes, engines, and propellers to identify, assess, and mitigate cybersecurity threats.
The regulations will apply to both new and modified aircraft systems, ensuring that cybersecurity measures are integrated throughout the lifecycle of aviation products.
The proposed changes will be incorporated into Title 14 of the Code of Federal Regulations, specifically parts 25, 33, and 35. These parts cover airworthiness standards for airplanes, aircraft engines, and propellers.
The FAA aims to standardize cybersecurity criteria, reducing certification costs and time while maintaining safety levels.

Addressing Cybersecurity Vulnerabilities
The increasing connectivity of airplane systems to internal and external networks has introduced new cybersecurity vulnerabilities. These vulnerabilities can arise from various sources, including field-loadable software, maintenance laptops, public networks, and portable electronic devices.
The FAA’s proposed rules aim to protect against intentional unauthorized electronic interactions (IUEI) that could pose safety hazards. The FAA will require applicants to conduct a comprehensive security risk analysis to achieve this.
This analysis will identify potential threats and assess their severity and likelihood of exploitation. Based on this assessment, applicants must implement mitigation measures to protect against these threats, ensuring the continued airworthiness and safety of the aircraft.
Harmonizing with International Standards
The FAA’s proposed rules are designed to align with international cybersecurity standards, particularly those set by the European Union Aviation Safety Agency (EASA).
EASA has already implemented similar cybersecurity provisions, and the FAA’s initiative aims to harmonize U.S. regulations with these international standards.
This harmonization will benefit manufacturers by providing a consistent set of requirements, reducing the complexity and cost of certification.
The proposed regulations also incorporate the recommendations of the Aviation Rulemaking Advisory Committee (ARAC) Aircraft System Information Security/Protection (ASISP) Working Group.
This group, comprising industry and government experts, has provided guidance on best practices for aircraft system cybersecurity, which the FAA has integrated into its proposed rulemaking.
Public Participation and Next Steps
The FAA is inviting public comments on the proposed cybersecurity regulations. Stakeholders, including manufacturers, operators, and the general public, are encouraged to provide feedback on the potential impacts of these rules.
The FAA will consider all comments before finalizing the regulations, ensuring they address industry needs while maintaining high safety standards.
The proposed regulations represent a proactive approach to addressing cybersecurity threats in aviation. By standardizing cybersecurity criteria and aligning with international standards, the FAA aims to enhance the safety and security of modern aircraft systems.
As the aviation industry evolves, these regulations will play a crucial role in safeguarding against emerging threats.
