Analysis of Causes and Countermeasures of Helicopter Accident from the Engineering Viewpoint

The helicopter crashes result in pilot death, considerable economic loss, and potentially bad damage to nearby residents. Thus, there needs to be a thorough investigation on causes of helicopter accidents and establishment of the prevention measures before another crash repeats. In the present research, the accident data of the last 30 years from US Army, EU Helicopter, and Korea government agencies (Forest Service, Police Agency, National Emergency Management Agency, and etc.) were studied. The causes of the accidents were classified into three fundamental models: human error, mechanical error, environment error. Additionally, the technical countermeasure was proposed to reduce the accident caused by each error.
