A Comparative Analysis of Aircraft Accident Investigation Models for Enhancing Aviation Safety and Sustainable Infrastructure

Objective: The purpose of this research is to compare the accident causality models used in the literature on the worldwide air transport industry with the models utilized in Turkish aviation safety theses. By guaranteeing aviation safety using models that have been continuously improved from the past to the present, it seeks to assure a sustainable aviation industry. The study intends to support future research as well as the body of knowledge in this area. Theoretical Framework: The concept of safety has undergone continuous evolution in parallel with technological advancements. Various accident causation models, such as the SHELL Model, HFACS Model, Swiss Cheese Model, and 5M Model, have been developed in different sectors to understand the root causes of accidents and implement preventive measures. These models form the foundation for understanding the causes of aviation accidents and the preventive safety measures associated with them. Methodology: The study adopts a systematic literature review combined with bibliometric analysis. Theses related to aviation safety from the National Thesis Database have been systematically examined. The frequency and contexts in which accident causation models are utilized in these theses have been analyzed. Findings and Discussion: The analysis revealed that the most frequently cited models in theses related to aviation safety in Turkiye are the SHELL Model, HFACS Model, Swiss Cheese Model, and 5M Model. Additionally, it was found that a significant number of these theses were written at Anadolu University and Istanbul Gelisim University. The studies in which accident causation models were most prominently featured were conducted in 2019. These findings were discussed in the context of the theoretical framework, and their implications for safety research and sectoral practices were evaluated. Research Implications: This study highlights the importance of a systematic comparison between local and international practices. The findings provide insights into academic trends in Turkiye and point to areas where improvements can be made in future studies. Originality/Value: The systematic analysis of accident causation models used in aviation safety theses in Turkiye adds unique value to the study. By emphasizing widely used models, academic trends, and the importance of alignment with international standards, the study contributes to the literature.
