The Prevention Bulletin is an established tool of preventive safety policy in the Swiss aviation sector. It uses findings from preliminary investigations to systematically identify and disseminate safety risks—without the administrative burden of a full investigation. The publication contributes to the continuous improvement of flight safety.

Detailed Summary

Prevention Bulletins are published in accordance with Article 56 of the Ordinance on Safety Investigations of Incidents (OSII). They contain factual information obtained from preliminary investigations and are intended to contribute to the prevention of accidents and serious incidents.

The bulletins follow a chronological structure and record those incidents whose preliminary investigations have been completed by the end of a quarter. The published information is anonymized and makes no claim to completeness. It is directed at the affected aviation circles and is intended to sharpen their safety awareness.

Key Points

  • SSIB regularly publishes Prevention Bulletins based on completed preliminary investigations
  • Bulletins serve accident prevention and safety culture in aviation
  • Information is anonymized and updated quarterly

Critical Questions

  1. Data Quality: What criteria determine whether an incident is included in the preliminary investigation and does not directly lead to a formal investigation?

  2. Representativeness: Is the bulletin a complete overview of safety-relevant incidents, or can systematic gaps arise through filtering by efficiency criteria?

  3. Anonymization and Utility: How is it ensured that anonymization does not reduce the information value for aviation companies so much that concrete measures become difficult?

  4. Language Version: Why is the German version defined as the original? Can translations lead to misunderstandings in implementation?

  5. Feedback Mechanism: Is there a system to verify whether the information from the bulletins actually leads to improvements in practice?
