What are the main investigation phases?

• A. Notification, on-site field investigation, analysis, final report, and safety recommendations
• B. Planning, execution, review, closure
• C. Initiation, data collection, dissemination, audit
• D. Notification, analysis, conclusion, enforcement

Answer: (A)

Investigations in aviation safety follow a defined lifecycle: notification, field investigation on-site, analysis, final report, and safety recommendations. This sequence ensures a timely alert to stakeholders, thorough evidence gathering at the scene, careful analysis to identify causes and contributing factors, a comprehensive final report documenting findings, and actionable recommendations to prevent recurrence. The option that lists these phases directly aligns with how real-world investigations are organized, reflecting the end-to-end process from initial awareness to guidance for safety improvements. The other options describe processes that resemble project management or broader organizational activities—planning and execution, review and closure; initiation and data collection with dissemination and audit; or notification and analysis followed by conclusion and enforcement. Enforcement is typically a regulatory action that follows investigation findings, not a phase of the investigation itself, so those sequences don’t match the standard investigation lifecycle.
