In aviation mishap investigations, what is forensic engineering?

• A. The process of interviewing witnesses to reconstruct events.
• B. The application of engineering analysis and testing to determine failure modes and root causes in damaged components or structures.
• C. The legal process for determining airline fault.
• D. The practice of restoring damaged parts for reuse.

Answer: (B)

Forensic engineering in aviation mishap investigations is the application of engineering analysis and testing to determine how a component or structure failed, including the failure modes and root causes. It involves examining damaged parts, material properties, design and manufacturing details, maintenance history, and environmental or loading conditions, then using tools like destructive and non-destructive testing, fractography, material testing, and modeling to reconstruct the sequence that led to the failure. The goal is to identify the underlying reasons a failure occurred and contributing factors to prevent recurrence and improve safety. It’s not about interviewing witnesses, determining fault in a legal sense, or restoring parts for reuse, which are outside the core engineering analysis.
