In this study, we attempted to examine how the management commitment and safety communication affect the safety behavior of flight crew members while performing their duties. In addition, we attempted to examine how the individual cultural values ​​of each flight crew are involved and influenced in such influence relationships. As a result of the study, among the sub-variables of safety behavior, the relationship between commitment to safety compliance and communication was found to have no statistically significant effect (∆R2 = .049, p = .5), and the relationship between commitment to safety participation and communication was found to had a statistically significant effect (∆R2 = .088, p < .001). As a result of examining the moderating effect of individual culture values ​​in the relationship between commitment to safety participation and communication, the moderating effect of uncertainty avoidance (β = .256, p < .05) showed statistically significant results, and management's commitment/communication The interaction effect between and uncertainty avoidance had a statistically significant effect when uncertainty avoidance was low, but was not statistically significant when uncertainty avoidance was high.
