Investigation reports
Where a critical industry or causal investigation is commenced an Investigation Information Release (IIR) is published (generally within 28 days) to share early learnings. A final report is published at the conclusion of the investigation.
The final reports provide information useful for a risk assessment, cause and circumstance of the incident, findings, and the actions taken after the incident.
