Key facts
The Swiss Transportation Safety Investigation Board (STSB) investigates accidents and serious incidents in public transport, civil aviation and oceangoing vessels. From among the roughly 2,100 reports it receives each year, it selects around 100 to investigate, based on the potential for improving safety. On the basis of the cause determined for the incidents, it makes safety recommendations to the supervisory authorities, including the Federal Office of Transport and the Federal Office of Civil Aviation, and sends safety advisories to the relevant industries. To ensure its independence, it is organised as an extra-parliamentary commission; administratively, it belongs to the Federal Department of the Environment, Transport, Energy and Communications.
