In spite of the numbers of aircraft mishaps, it is considered safer to travel by airplane than any other mode of transportation. Approximately 80% of aviation mishaps are attributed to human causes or errors. (Taylor, unknown) “Aviation accidents are the end result of a number of causes, only the last of which are the unsafe acts of the aircrew (Reason, 1990; Shappell & Wiegmann, 1997a; Heinrich, Peterson, & Roos, 1980; Bird, 1974).” (Shappell & Wiegmann) Because of the importance and critical nature of the effect of human factors, information regarding Human Factors, aircraft maintenance positions, training time and costs involved, and a look at the type of documentation used will be revealed. The intent is to educate of the need to enhance systems and safety measures already in place to achieve a lower human factor cause error.
