Abstract: Abstract Following the principles of systemic accident models, in this paper we presented a new framework for modeling organizational aspect of hierarchical safety control structure in complex Socio-Technical Systems. In fact, we introduced a Specific Organizational Feedback Control Loop together with a Customized Process Model to narrow down System Theoretic Process Analysis (STPA) risk analysis method. Clearly, this modification can be able to adjust STPA for deficiency analysis of organizational safety control structure. As a case study, we used this framework in an aircraft maintenance industry, as a sample system. Indeed, we modeled and analyzed this system’s organizational safety control structure by our new framework. We demonstrated that, the new framework, as a modified version of STPA, can accurately model and analyze the organizational control mechanisms.
