In today world, people became more time conscious and luxury loving, which resulted in the diversion of people's attention from ancient means of transportation to the modern ways i.e. aviation. The transition not only facilitated people but increased the air traffic and the number of aviation accidents as well. The purpose of this study is to find out the major causes of the aviation accidents in different segments of aviation operation in United States We obtained the data for a period of 24 years from Jan 1992 to Dec 2015, from two different data bases; a NASA maintained database " Aviation safety reporting system " (ASRS) [1] and National transportation safety board (NTSB) maintained database " Aviation accident and incident data system " (AIDS) [2]. The data for each segment of the operation were separately organized to use the correlation among the accidents and further descriptive statistical tools were used to show and evaluate the relationship between the factors affecting the accidents. To see the accidents more closely, we grouped the accidents into three segments of aviation operations: General Aviation (GA), CFR 14 Part 135 and CFR 14 Part 121. We found that the size of the flight, terrain, and seasonal effects have significant influence on the number of aviation accidents in United States. The General Aviation, which is the smallest segment of aviation operation dominates over other segments' accident (CFR 14 Parts 121 and 135). It caused for 97.5 % of all aviation accidents. The data also shows the significance of seasonal trend that 44% of all aviation accidents took place between the months of May and August. At the end of the study we present recommendations for policy makers and a mathematical model that forecast the upcoming unfavorable events in the aviation and to give timely remedies to reduce the accidents in aviation industry to a certain level.
