The study of the vulnerabilities of a system is often organized in a hazard analysis. Methods based on systems thinking are relevant tools to analyze the operation of modern products. The purpose of this research is to develop, implement, and validate a systems-based model for aviation Safety Management Systems (SMS) incorporating the treatment of collected data to foster the effectiveness of mitigating measures over time. The model uses data monitoring systems, management of change reports, flight inspections, voluntary reports, and other sources as input messages to an Active Hazard Analysis. The new requirements, constraints, and the preventing and mitigating measures are organized and delivered timely to the operators. The analysis on unstable approaches found contributions to documentation and procedures in practice. In accordance with SMS standards, the new framework provides organized safety information for management, fostering better planning on the use of workforce and resources.
