Summary of Windshear Accidents and Views About Prevention 861697
Although windshear has been an atmospheric phenomenon since the beginning of time, the extent to which windshear presents a hazard to air carrier aircraft has been acknowledged only during the past 15 years. Since 1970, the Safety Board has identified a low altitude encounter with windshear as a cause or contributing factor in 13 accidents involving transport category airplanes. Seven of these accidents were fatal and accounted for 575 deaths. The circumstances of those accidents which exemplify the hazards to aircraft during approach and departure through low altitude windshear are discussed as are recommendations of the Safety Board for preventing these accidents, and the Safety Board's continuing concerns about the hazard.
