In order to study the current status of airline employees’ safety integrity and existing problems, safety integrity scale of airline employees was designed firstly. Structural dimensions of the airline employees' safety integrity scale are determined under the guidance of safety integrity psychological mechanism and measurement theory. Initial measurement problems were determined by using typical cases analysis and semistructured interviews etc. Formal scale was formed after measurement problems had been analyzed by project analysis, exploratory factor analysis, validity test and consistency reliability test. Preliminary investigation was done with this scale, and the investigation covered 7 local civil aviation administrations and 25 airlines. Data was analyzed by using independent samplet test, variance analysis, multiple analysis, and nonparametric test. Analysis results show that the final safety integrity scores of airline employees whose seniority arebless than 1 years are significantly lower than that of those with a seniority of 5-10; the final safety integrity scores of middle grade professional employees are significantly higher than those of junior and senior grade professional employees, and the scores of 5 measurement dimensions of junior grade professional employees are significantly lower than those of middle or senior grade professional employees, and the scores of safety integrity will of senior grade professional employees are significantly lower than those of middle or senior grade professional employees; the final safety integrity scores of the aircraft group dimensions “51-100” are significantly higher than the other 3 groups; the safety integrity level of different genders, marriages, ages, incomes, regions are not significant.
