When is immediate notification to the NTSB required?

Immediate notification to the National Transportation Safety Board (NTSB) is required specifically in the event of an aircraft accident or in the occurrence of certain serious abnormalities that significantly affect the aircraft's operation or safety. An accident is defined as an occurrence associated with the operation of an aircraft in which any person suffers fatal or serious injury, or in which the aircraft is substantially damaged.

This requirement ensures that the NTSB can conduct timely investigations, gather facts, and develop safety recommendations to prevent future occurrences. Reporting also supports the overall aviation safety framework by promoting accountability and enhancing operational safety culture within the industry.

Routine operations, flight deviations, and events based solely on anniversary dates do not trigger this immediate notification requirement, as the thresholds for reporting to the NTSB are specifically defined around safety-critical incidents.
