ABSTRACT	The worldwide aircraft accident database,which covers most of the fatal or hull-loss accidents of aircraft heavier than 5,700kg since 1954 has been developed to study the most critical factors causing accidents and to improve air transport sefety.As examples of accident data analyses,major accident causes,secondary factors inducing pilot errors which are responsible for most accidents,and the chronological changes in accident patterns have been discussed.Moreover,interest was primarily focused on the accidents which were induced by inadequate design or manufaco four groups.They are three Ms and one E,namely Man,Mschine,Management and Envinment.It was pointed out that carelessness of the maintenance staff,defects during manufacturing and improper management on the part of the operator or the authority are also major affecting elements for the accidents induced by structural failures.
