Which of the following incidents must be reported to the NTSB?

The requirement to report specific incidents to the National Transportation Safety Board (NTSB) is outlined in Title 49 of the Code of Federal Regulations (49 CFR Part 830). Among the conditions that necessitate reporting, incidents involving property damage that exceeds $25,000 are significant due to their potential implications for safety and regulatory oversight.

When property damage surpasses this monetary threshold, it suggests that the incident could indicate a more substantial risk to safety in aviation operations. This reporting ensures that the NTSB and relevant authorities can investigate, analyze the causes, and implement necessary measures to improve safety standards and practices.

In contrast, while collisions on the ground, passenger illnesses, and fires on the ground are serious events, not all incidents of these types automatically fall under the reporting requirements set by the NTSB unless they meet specific criteria, such as injury or substantial damage. Understanding the precise thresholds for reporting helps pilots and operators maintain compliance with regulatory obligations while promoting a culture of safety in aviation.
