This Thesis presents an overview of a research effort to improve aviation safety by managing and analyzing human factors in aviation maintenance by exploring reasons and regulations which have been involved all aircraft personnel who are maintaining commercial aircraft to have a deep understanding of the role that human factors play in the safety of the airlines maintenance and overhaul industry in general and in Saudi Arabian Airlines in particular then it will provides advanced future solutions to satisfy the aviation expansion and its future needs while importance of this research on chapter 1 lies in the fact that a huge percentage of maintenance mistakes involve human factors where the majority of all aviation maintenance incidents and accidents are the result of human error Furthermore the maintenance world has unique Human Factors issues that are more severe and longer lasting than elsewhere in other aviation fields moreover according to the research issues, research questions, research objectives, methodology, results, and implications of the results to theory and practices will provides a unique perspective on aviation safety by focusing on everyday’s challenges that airplane’s technician face and its effects on general aviation safety rather than other safety discipline. this research collected and employs mixed research methodology quantitative and qualitative while evaluating variables through hypothesis testing, analyzed using the frequency distribution on chapter 3 and 4, the findings of the study suggest that the most common cause of aviation accidents related to maintenance is unsafely system operation, and the most likely reasons for the human errors in aviation maintenance is stress, it aims to provide improvement solutions and to introduce new and modern ways of applications that can bridge certain aviation maintenance gaps of the associated subjects on chapter 2 by effective ways of doing that such like implementing and designing a Step by step assembly instructions interactive electronic version of technical manual (Smart Z-tech. manual) and (digital scale tool box) where aviation technicians need such instructions photos and diagrams that could quickly help them to assemble components or to locate component’s parts to its precise location by using such a technique without flipping any single sheet of manual papers and with a minor chance to commit a human error or mistake which leads in the end to improve aviation safety. Key words Aviation Safety Human Factors Human Errors Aircraft maintenance.
