ED-203A - Airworthiness Security Methods and Considerations

We are pleased to announce the publication of ED-203A|Airworthiness Security Methods and Considerations.
Airworthiness security is the protection of the airworthiness of an aircraft from intentional unauthorized electronic interaction. Existing safety processes have not had to consider intentional disruption. This document provides methods and considerations for showing compliance for airworthiness security during the aircraft life cycle. It was developed as a companion document to ED-202A / DO-326A "Airworthiness Security Process Specification" which addresses security aspects of aircraft certification and to ED-204 / DO-355, "Information Security Guidance for Continuing Airworthiness" which addresses airworthiness security for continued airworthiness. The methods and considerations of this document provide guidance for accomplishing the airworthiness security process activities identified in ED-202A / DO-326A.
