Swiss Transportation Safety Investigation Board STSB

Welcome to the homepage of the STSB

The Swiss Transportation Safety Investigation Board (STSB) is the State authority of the Swiss Confederation which has a mandate to investigate accidents and dangerous incidents involving trains, aircraft, inland navigation ships, and seagoing vessels. The aim of this activity is to determine not only the direct causes of such events but also the more deep-seated reasons and other risks associated with them. This sole objective of this form of investigation is to acquire insights by means of which future accidents and hazardous situations can be prevented and which result in improved safety. However, the results of such a safety investigation are not intended to clarify questions of blame and liability.
