With the increasing complexity of aviation system, the flight safety accident analysis becomes more difficult. Human factors in safety accidents are often the result of the interaction of multiple sub components in the system. The safety measures can’t be formulated on the basis of a single component. The traditional ATHEANA method is based on the identification of unsafety action and error forcing context to analyze the formation mechanism of human factors. Due to the lack of systematic analysis method, the identification of UA and EFC is often insufficient. Therefore, a hybrid method of ATHEANA-STPA is proposed to analyze aviation human factors. Through the definition of system risk factors and the construction of system control model, we can have a clearer understanding of the process of the accident. Based on the system control model and accident description, the UA is identified within the problem boundary. By comparing the human performance factors, the EFC of UA is discriminated. The formulation of UA control measures is based on the prevention and control of EFC. Through the control of each EFC in the accident chain, the prevention of human factors can be realized, and finally achieve the purpose of accident risk control.
