Abstract: In order to reduce the influence of human factors in aircraft MRO, typical aircraft accidents of a domestic company are analyzed. The improved HFACS model for aircraft MRO is constructed, which can analyze the human factors more effectively with its 17 subcategories. SPSS is employed for chi-square test and odd ratio analysis. Results show that the organization influence is the main cause of accidents, meanwhile, there exists significant causal relation among organization influence, unsafe supervision, premise of unsafe behavior and unsafe behaviors. The correlation between sub-categories should be given more attention in order to fundamentally reduce the occurrence of human factor events.

Key words: aircraft maintenance, human factor, improved HFACS, chi-square test, odd ratio
