Introduction
Digital technology has become deeply integrated into modern aviation. Maintenance planning, continuing airworthiness management, technical records, operational communications and aircraft data increasingly depend on connected digital systems.
This transformation has brought significant improvements in efficiency and accessibility. However, it has also introduced new risks. In aviation, a cybersecurity incident can affect considerably more than confidential information. Depending on the systems involved, it can disrupt operations, compromise the integrity or availability of critical data and potentially have implications for aviation safety.
For operators and aviation organisations, cybersecurity is therefore becoming part of a much broader responsibility: protecting the reliability and continuity of the systems on which modern aviation depends.
Aviation Is Becoming Increasingly Connected
Digitalization now extends throughout the aircraft lifecycle. Electronic technical logs, digital maintenance records, aircraft health monitoring, predictive analytics and digital parts tracking are among the technologies being adopted across technical operations. IATA’s Digital Aircraft Operations programme specifically identifies these areas as part of the industry’s transition toward increasingly connected aircraft and airline operations.
The benefits are substantial. Information can be accessed and exchanged faster, maintenance decisions can be supported by larger quantities of operational data, and technical teams can coordinate activities more efficiently.
Greater connectivity, however, also creates greater dependence on the availability and integrity of digital information.
Cybersecurity Is an Operational Issue
Aviation cybersecurity should consequently not be considered solely an IT responsibility.
ICAO identifies aviation’s extensive interconnectivity and complexity as important factors in its exposure to cyber threats. A successful cyberattack may affect finances and reputation, but ICAO also identifies potential consequences for continuity of services, safety and security.
Consider a continuing airworthiness environment. Maintenance status, Airworthiness Directive compliance, component information and technical records all contribute to decisions about whether an aircraft can safely and legally operate.
Protecting this information therefore means considering three fundamental questions: Is the information confidential where necessary? Is it accurate and protected against unauthorized modification? And will it remain available when personnel need it?
The answers can have direct operational consequences.
Regulation Is Evolving With the Risk
European aviation regulation increasingly reflects this relationship between information security and aviation safety.
EASA’s Part-IS framework establishes requirements for identifying and managing information-security risks that could affect aviation safety. It also introduces requirements concerning the detection of information-security events and the response to and recovery from relevant incidents.
Importantly for the continuing airworthiness sector, the framework applies to organisations including relevant Part-CAMO and Part-145 organisations, as well as air operators and other aviation entities within its scope. The regulatory framework therefore reinforces an important principle: cybersecurity and aviation safety can no longer always be managed as completely separate disciplines.
Resilience Requires More Than Technology
Effective cybersecurity does not begin and end with software.
People, processes, suppliers and organisational procedures all influence how effectively an aviation organisation can manage information-security risk. IATA describes aviation cybersecurity in terms of maintaining safe, secure and resilient operations, and its current guidance encompasses governance, responsibilities, security culture, awareness, training and risk management.
ICAO takes a similarly broad approach. Its Aviation Cybersecurity Strategy is structured around seven pillars, including governance, legislation and regulation, information sharing, incident management, emergency planning, training and cybersecurity culture.
This makes resilience particularly important. No organisation can reasonably assume that every cybersecurity incident can be prevented. Organisations must also be capable of identifying incidents, limiting their consequences, maintaining essential functions where possible and recovering effectively.
Protecting the Wider Aviation Ecosystem
Another challenge is that aviation organisations rarely operate independently.
Operators interact with CAMOs, maintenance organisations, airports, OEMs, suppliers, software providers, authorities and numerous other partners. Information and systems regularly cross organisational boundaries.
Cybersecurity therefore also requires cooperation. ICAO explicitly emphasizes international and industry collaboration because aviation systems and data flows extend across individual organisations and national borders.
A weakness affecting one organisation or supplier can consequently create challenges elsewhere in the operational chain.
Cybersecurity as Part of Modern Aviation Management
Digitalization will continue to transform aviation. The objective should not be to resist that transformation, but to ensure that technological progress is accompanied by appropriate protection, oversight and organisational awareness.
For operators and technical organisations, this means treating cybersecurity as part of operational resilience rather than simply as protection against data theft.
At Arpiem, continuing airworthiness and technical management increasingly operate within this connected environment. Maintaining reliable processes, accurate technical information and effective compliance requires recognising the importance of the digital systems that support them.
As aviation becomes more connected, protecting those systems ultimately means protecting something much larger than data: the continuity, reliability and safety of aviation operations.
