Pilot behaviors, i.e. unsafe acts, are the direct causes of aviation accidents. Accident investigation analyses have revealed that several different factors from individual to organizational level contributed to the aviation accident occurrence. Airline companies have implemented Crew resource management (CRM) to prevent unsafe acts to improve flight safety, and CRM has been widely used since its first initiation. To enhance flight safety, it is crucial to measure both unsafe acts and Crew Resource Management (CRM), as this helps analyze their relationship and identify other factors contributing to unsafe behaviors. Existing tools to measure CRM and unsafe acts were dependent on the expert ratings requiring comprehensive training. Therefore, the need for easy-to-use measurement tools has emerged. To fill this gap, Study 1 aimed to develop self-report CRM Competency Scale by conducting interviews with 12 commercial airline pilots. The previously developed Airline Pilot Behavior Inventory was revised to capture wider aspects of unsafe acts. In the main study with 176 commercial airline pilots, factor structures of both tools were explored. Hierarchical regression analysis was conducted to examine the predictors of unsafe acts stressing the predictor roles of CRM competencies, fatigue, safety climate, and personality traits. Results showed importance of CRM competencies, personality traits, and fatigue as the predictors of the pilots’ unsafe acts. Results revealed the mediating role of safety climate and fatigue in the relationship between CRM and unsafe acts. Neuroticism, as a personality trait, played a moderating role in the relationship between CRM and unsafe acts.
