In order to enhance the classification, analysis and utilization of safety information, China civil aviation develops a more suitable model named “Occurrence Human Factors Analysis Model(OHFAM)” ,which based on the “Human Factors Analysis and Classification System” (HFACS) and the actual operation conditions and characteristics of China civil aviation. This model consists of five layers and especially adds the layer of “Government Supervision” which reflects the deficiency of regulatory authorities in Safety Supervision. On the basis of safety information analysis and extensive research, OHFAM considers safety culture and operational characteristics of China civil aviation, and offers five layers in details from flight, maintenance and air traffic control. In this paper, the basic elements and functions of OHFAM are introduced. And then we use this model to analyze the incidents of the last five years (2006-2010) of China, and sum up the main contributing factors.
