Abstract: The aircraft communications addressing and reporting system (ACARS) is a key data lnk system affecting flightsafety and operational efficiency of civil aviation. Ensuring its airworthiness is a fundamental prerequisite for typecertification. To address cybersecurity risks posed by the networking of airborne systems, which traditional certi-fication methods cannot fully cover, this paper systematically analyzes civil aviation regulations and relevant in-dustry standards, and establishes an ainworthiness framework for the ACARS data link. This framework providesan integrated compliance matrix, which maps specific airworthiness clauses involving basic functions, redundan-cy design, system safety and continued ainworthiness to verification activities such as design review, analysis andtesting. In addition, it clarifies the certification path for introducing cybersecurity verification in the form of spe-cial conditions. The framework constructed in this paper provides a structured idea and standardized process forthe compliance verification of the ACARS data link, aiming to improve the systematicity and integrity of the cer-tification work.
