Aviation industry in accordance with its development and use of sophisticated techniques and technology has faced many repeated air accidents. Any event that happened in the past can be used as a historical experience in order to prevent similar disasters in the future. In other word, evaluating and analyzing the past events can be used to identify the potential factors which cause the air accidents. In addition, exact investigation of these factors could be a solution for reducing these accidents. In order to be much closer to this goal, comprehensive database should be designed and also be accessible for administrators, technical managers and the strategic and operational levels to maintain the readiness and minimize damage to the aviation industry. This study is a theoretical research in the field of air accidents to present a comprehensive model of flight database and operation in order to prevent the occurrence of similar accidents. The population of the research consists of aviation accident experts in aviation industry. Non probability sampling method is used to determine the sample of this research. Data collection is done by in-person questionnaire and archival data. The research method is field- descriptive. The results show the importance of database design to increase the flights’ safety factors of aviation industry.
