Which incident requires an immediate notification to be made to the nearest NTSB field office?

• A. An overdue aircraft believed to be involved in an accident
• B. A routine taxiway incident
• C. A routine cabin odor
• D. A minor door warning

Answer: (A)

Immediate notification to the nearest NTSB field office is required when there is an aircraft accident, or when an aircraft is overdue and believed to be involved in an accident. In this situation, the overdue aircraft believed to be involved fits that threshold because it suggests a potential accident and calls for rapid NTSB awareness and response so search, rescue, and investigation steps can begin promptly.

Routine taxiway incidents, cabin odors, or minor door warnings don’t meet the threshold for immediate NTSB notification. They’re considered normal operational issues and are typically handled through standard reporting and maintenance processes unless they involve an actual accident or serious injury.
