Which incident would necessitate an immediate notification to the nearest NTSB field office?

• A. An in-flight fire
• B. A door latch failure during taxi
• C. A minor turbulence encounter
• D. A squeak in the landing gear

Answer: (A)

An in-flight fire triggers immediate notification to the nearest NTSB field office because it represents a serious, safety-critical event with the potential for catastrophic consequences. The NTSB investigates significant aviation accidents and certain incidents, and prompt reporting helps preserve evidence and allow a timely assessment of causes and safety improvements.

In contrast, a door latch failure during taxi is a ground handling issue that would typically be handled through maintenance procedures; minor turbulence is a common flight condition and doesn’t by itself require immediate NTSB notification; a squeak in the landing gear is a minor mechanical concern and not an incident that would demand urgent reporting.
