During a secondary investigation, what should be done?

• A. report obvious signs of damage
• B. record only what you can see
• C. locate and report unseen or hidden damage
• D. ignore non-obvious damage unless instructed

Answer: (C)

In a secondary investigation, you look for damage that isn’t obviously visible. Hidden damage can be lurking behind panels, inside compartments, or within structural and system interfaces, and it can worsen if not found and addressed.

This approach is best because it ensures a complete picture of safety and readiness. By systematically inspecting for unseen or hidden damage—checking for moisture, corrosion, delamination, leaks, heat damage, cracks, and electrical issues, and using appropriate tools—you can identify problems that would otherwise go undetected. Documenting these findings and reporting them promptly allows proper repair planning and prevents surprises later.

Reporting only what you can see misses critical issues, and ignoring non-obvious damage isn’t safe or prudent for maintaining integrity and safety. Focus on uncovering and reporting the unseen so the crew can address all hazards and restore the ship to full capability.
