The "Human" Error Factor that could be prior prevented or could be an avoidable mistake is widely involved in complicated operation process or just has been in the environment. Reasonable decision makers assume that we humans are reasonable and objective and will certainly make decision between the biggest benefit and the smallest loss. However, the school of behavior found out through empirical research (Kahneman & Tversky, 1979) that we humans just won't make decision base on a reasonable, objective or econometric way to search for their final goal but to make decision through person preferences. Risk means the uncertainty of life and with an outcome to influence human life; risk focuses on future possibility and future uncertainty. Therefore, main purpose of this research is to discuss how the different Risk Perception and Risk Propensity from maintenance crew can influence the factor of Human Error. In summary, this research discovers that: (1) Other than education element of population variable, there is also with great difference to Risk Propensity among different genders, organizations, departments, ages and numbers of years in employment. (2)There's no big difference between the degree of familiarity and Risk Perception, and an inverse correlation between organizational control and Risk Perception; Risk perception, Risk Propensity and Human Error are all in positive correlation. (3) There is obvious difference of Risk Perception between High/Low degree of familiarity or High/Low degree of organizational control from/to maintenance crew. (4) There is obvious difference of Human Error between High/Low degree of Risk perception or High/Low degree of Risk Propensity from maintenance crew. (5) Risk Perception will not influence Human Error by the interference of Risk Propensity. (6) The degree of familiarity and organizational control can predict and explain Risk Perception. (7) Risk Perception and Risk Propensity can predict and explain Human Error. Key Words: Familiarity, Organizational Control, Risk Perception, Risk Propensity, Human Error
