2025, EASA Part IS in U-Space Operations: Is System-Theoretic Process Analysis for Security Sufficient to Meet Information Security Risk Assessment Requirements?, Linz, Elsevier BV), p. 2448-2457), ISSN 1877-0509

The U-space implementation within airspace management has led to the emergence of research activities focused on information exchange between U-space stakeholders. U-space requires information exchange among various entities, including the Air Navigation Service Provider, U-space Service Provider, Common Information Service Provider, Unmanned Aircraft Systems, and remote pilots. This information must be secured. European Part-IS addresses information security risks by establishing processes to safeguard information used, transmitted, or received during U-Space operations. This paper investigates whether the System-Theoretic Process Analysis for Security (STPA-Sec) can ensure compliance with EASA Part-IS information security risk assessment requirements. By applying the analysis to the CISp operation concept and comparing the outcomes with Part-IS requirements, the results indicate that while STPA-Sec effectively identifies potential security vulnerabilities and hazards, it does not provide specific mitigation recommendations. Therefore, while STPA-Sec can inform the development of security strategies, additional steps are needed to fully comply with EASA Part-IS requirements.

Authorities in civil aviation and other high-risk industries are currently making a progressive shift from compliance-based to performance-based oversight. This entails many challenges where among the foundational ones lies the issue of establishing effective performance-based checklists to be used when auditing organizations. This paper addresses the issue with a systemic approach to safety, namely the System-Theoretic Accident Model and Processes, which treats safety differently from its predecessors. The model is used to infer performance-based audit questions for selected type of aviation organization based on regulatory requirements, thus extending the compliance-based approach by broader reasoning about safety issues. The questions were tested with the Civil Aviation Authority during real-scale audit and the conclusions show that this is a promising approach to reduce the currently used subjective approach to evaluation of the actual performance, with many practical benefits for the Authority.

Abstract: Advanced Air Mobility (AAM) vehicles can serve a wide range of operations, supporting passenger and cargo movements within and between urban and rural environments. Novel risks emerge from AAM systems with respect to both airborne and ground segments, calling for the adoption of systems theory and a systemic perspective for safety risk management. In this domain, Systems Theoretic Accident Modelling and Processes (STAMP) is an accident causality model that considers safety as a continuous control task. The scientific literature already offers some applications of STAMP and its nested techniques, i.e., System-Theoretic Process Analysis (STPA) and Causal Analysis based on System Theory (CAST), for investigating the safety management in the AAM domain. However, to the best of our knowledge, no contributions use as a unit of analysis the management of safe operations for an AAM system by adopting an integrated perspective to account for the interactions among different kinds of vehicles within vertiports and airports. For this reason, the manuscript proposes a systemic analysis for the safety management of electric Vertical Take-Off and Landing (eVTOL) vehicles operating at a vertiport located inside an airport. We employed the STPA technique, whose usage has been enhanced thanks to a standardized and neutralized taxonomy describing human factors involved in the operations. This allowed for embracing a no-blame and non-judgemental human perspective, which benefits from the systemic view offered by STPA.

Maintenance-related problems are one of the causal factors in microlight aircraft serious incidents and accidents. Maintenance of microlight aircraft in the Czech Republic is primarily the responsibility of the owner of the microlight aircraft and in the supervision of national regulator for microlight aircraft (a maximum weight of 600 kg) - the Light Aircraft Association (LAA) of the Czech Republic. The aim of this paper is to develop a set of systemic safety recommendations for the maintenance of microlight aircraft in the Czech Republic that could contribute to increase the level of aviation safety throughout the making of tailored safety constraints to deal with new microlight aircraft types or the transition of new users from general aviation to microlight aviation. For the definition of the safety recommendations, the STAMP model and the STPA methodology have been chosen as the most suitable for the complexity of the maintenance of the microlight aircraft. The STPA analysis was applied to the microlight

Maintenance, Repair, and Overhaul (MRO) organizations are one of the pillars of aviation safety. They ensure the airworthiness of aircraft in accordance with regulatory requirements. In Europe, until the recent changes in legislation, safety was part of quality and compliance management. Today, MROs are required to implement a Safety Management System (SMS). The paper focuses on MRO hazard and risk register, proposing a sample register with a procedure how to develop it. The proposed solution integrates with other parts of the integrated management system, such as quality control or occupational health and safety. The hazard and risk register was proposed using the recent approach of the System-Theoretic Accident Model and Processes (STAMP) accident causality model, suitable for complex sociotechnical systems, which are typical in the aviation today. The proposed solution allows the assessment of the system as a whole, which leads to the identification of new types of hazards and structuring of the existing ones. The presented study was performed with two European MROs to evaluate and validate its outputs.

Accidents and incidents bring to the Civil Aviation Authority (CAA) necessary data to understand the current level of safety in the state. Their investigation is carried out by the safety investigation authority capable to perform independent investigation activities in the state or authorized organizations. The final reports often include safety recommendations that the organization or CAA should apply in the form of corrective actions. Since most accidents are the result of several causal factors, there is an opportunity to investigate occurrences using a systemic approach to safety. One of the methods that can be used to identify system safety issues is STAMP-based Casual Analysis based on Systems Theory (CAST). The full application of the CAST at the state level requires some changes in the processing of safety data today. The goal of this paper was to create a concept of using data for the investigation of air accidents with the CAST analysis. Then to study the usability of the CAST to process safety data at the state level, primarily under the state oversight of the Czech Republic. The proposed concept presented with marked components of the CAST and the necessary data and information for the investigation according to this methodology. The concept shows where changes would need to be made to the current system setting to use the CAST at the state level without limitations.

Maintenance, Repair, and Overhaul (MRO) is one of the basic pillars of aviation. Continuing airworthiness involves a lot of maintenance staff that works on-site and MRO management has to take care of their workplace safety. The number of hazards in the maintenance workplace is high; mechanics can find a list of warnings and precautions in manuals and other documents to maintain the aircraft. Using maintenance manuals and investigation data, workplace safety specialists prepare tailored workplace safety requirements for each maintenance task. Workplace safety in MRO is a complex problem, yet the current requirements are based on linear causality. Their output is thus limited and cannot fully ensure workplace safety in MRO. Some studies describe workplace safety using a systemic approach to safety, however, none was focused on the MRO field. In our research, we applied a systemic approach to workplace safety in MRO. We used the System-Theoretic Process Analysis (STPA) and prepared a list of systemic requirements for MRO organization. The list was validated in real aviation organizations with the conclusion that it can help cover more safety issues and ensure a higher level of workplace safety in the MRO than the current approach.

The Safety Data Collection and Processing System (SDCPS) at aviation authorities is an important component for maintaining flight safety. Aviation safety occurrences are often the result of several deficiencies in the system, which brings the need to examine the system as a socio-technical whole. The System-Theoretic Accident Model and Processes (STAMP) is one of the systemic safety prediction models that deals with socio-technical systems and offers a possible solution for new approach to the safety data collection and processing. This paper focuses on the use of STAMP for SDCPS at aviation authorities. The methodology in this paper is based on the use of Business Process Modeling Notation (BPMN) tool for graphical algorithmic representation of processes according to the theory. This approach provides a systemic platform for proposal of safety data collection and processing. The resulting proposal to be used with SDCPS shows how to use the systemic approach of STAMP within current SDCPS systems and compares it with the current practices and standards in the aviation.

The following paper is focused on safety data collection and processing in the Maintenance, Repair and Overhaul (MRO) organizations. The goal was to propose a way how to collect and process details of safety data using a total systems safety approach. The problem of details of safety data processing worries most of the companies, because there are unique information in it. For the safety analysis processes, one of the key steps was to choose a safety model. The Systems-Theoretic Accident Model and Process (STAMP) systemic safety model was chosen for the purpose. According to the results from the previous research, MRO processes were modeled using Business Process Model and Notation (BPMN). The resulting process model was extended by information needed for STAMP-based analyses. The result is a workflow proposal with several technical details that show how safety data collection and processing can be changed using STAMP. The proposed solution was successfully validated with Czech Airlines Technics a.s. and considered useful base for further development of MRO safety management systems.
