DO-326A Airworthiness Cybersecurity
by Nick Clark | Published April 25, 2026
DO-326A establishes airworthiness cybersecurity certification requirements for aviation. Health-monitoring fleet substrate provides architectural foundation.
DO-326A Frame
DO-326A (Airworthiness Security Process Specification) establishes aviation cybersecurity certification framework, integrated with DO-356A (Airworthiness Security Methods) and emerging DO-355A guidance.
Architecture Implications
Aviation cybersecurity certification requires structural support for threat assessment, vulnerability management, and emerging post-deployment monitoring.
Architectural Mapping
Health-monitoring fleet substrate provides continuous airworthiness monitoring. Governance-chain integrity supports cybersecurity vulnerability tracking. Composite admissibility supports multi-authority aviation cybersecurity operations.
Standard Evolution
DO-326A enforcement maturation and emerging EASA equivalent guidance push toward structurally-supported architecture.
