Which of the following events requires immediate NTSB notification?

• A. Engine oil change completed
• B. Damage over 25 thousand dollars
• C. Passenger medical event
• D. Flight plan filed

Answer: (B)

Immediate notification to the NTSB is required when an aircraft accident or a serious incident occurs, including property damage reaching a threshold (typically $25,000) or more, or when there is a fatality or serious injury. In this scenario, the event with damage over $25,000 clearly meets the notification threshold, so it requires prompt NTSB reporting. Routine maintenance like an engine oil change isn’t an incident or accident, a passenger medical event isn’t automatically reportable unless it becomes a serious injury, and filing a flight plan is standard administrative work that doesn’t trigger NTSB notification.
