How does the NTSB define an accident?

• A. An occurrence during operation causing death, serious injury, or substantial aircraft damage.
• B. Any minor incident that occurred during flight.
• C. An incident causing only cosmetic damage.
• D. An event that occurred on the ground before takeoff.

Answer: (A)

The main idea here is how the NTSB defines an accident: it is an occurrence during operation that results in death, serious injury, or substantial damage to the aircraft. This sets a clear threshold, so not every mishap qualifies as an accident—only those with one of these outcomes while the aircraft is in operation (from start of movement to completion of the incident). “During operation” covers the time the aircraft is being operated, including flight and surface movement, so events that happen while the aircraft is on the ground and not in operation don’t meet the definition. “Substantial damage” means damage serious enough to require major repair or replacement of the aircraft or its systems, not just cosmetic or minor damage. Therefore, an occurrence that causes death or serious injury, or results in substantial damage, is an accident, whereas minor incidents, cosmetic damage, or events occurring before takeoff on the ground do not fit the NTSB definition.
