Which of the following is NOT produced by the SIB?

• A. Formal Report (AFSAS)
• B. Briefing to the CA
• C. The final message
• D. Corrective action plan

Answer: (D)

When a Safety Investigation Board wraps up an investigation, its outputs are focused on documenting what happened and communicating how to improve safety. The formal report, often the official record (AFSAS), is the detailed, comprehensive document that lays out the facts, analysis, conclusions, and recommended safety actions. It serves as the authoritative account of the investigation.

A briefing to the CA is the formal presentation of those findings to the appropriate authority, ensuring they understand the conclusions, candor of the analysis, and the recommended safety measures that should be considered or implemented.

The final message is a concise closure communication that summarizes the investigation results and any immediate actions or considerations for stakeholders, completing the loop of the investigation process.

The corrective action plan, while closely related to implementing safety improvements, is not produced by the SIB as part of its standard deliverables. Instead, it is typically developed by the organization affected by the investigation (often with regulatory input) to outline specific actions, owners, and timelines to address the recommendations. The SIB may reference or monitor CAP elements, but drafting the plan itself is not its primary product.

So, the item not produced by the SIB is the corrective action plan.
