Two cessations and one new factual report (aviation) of the STSB available
Payerne, 24.12.2025 — Two cessations and one new factual report (aviation) are available on the website of the Swiss Transportation Safety Investigation Board (STSB):
- HB-SGU (cessation)
- D-6378 / HB-OQB (factual report)
- HB-TDA (cessation)
For several years, numerous safety investigations have not been completed in a timely manner, which has reduced their preventive effect. For this reason, the STSB will in future give greater priority to the level of detail of individual safety investigations, in compliance with the national and international legal framework. The primary factor determining the scope of a safety investigation and the associated report will be the preventive potential that can be expected from an investigation. All accidents and serious incidents will, as required by law, be subject to a safety investigation consisting of at least a preliminary investigation and a timely publication of the facts in the Prevention Bulletin. If an investigation is opened because an incident has sufficient preventive potential, the usual procedure will be followed in accordance with Art. 47 OSITI. Investigations that have already been opened are periodically reviewed for their prevention potential and, if necessary, concluded with a presentation of facts if this is expected to have a sufficient preventive effect. This prioritisation and scaling of all safety investigations and reports with a focus on prevention should enable the majority of safety investigations to be completed in a timely manner in future.
