What is the primary difference between a reportable aviation incident and an accident?

The primary distinction between a reportable aviation incident and an accident lies in the severity of the occurrence, specifically regarding outcomes or potential for harm. An accident typically involves significant damage to the aircraft or injury to persons, and it usually meets specific criteria set by aviation authorities that categorize events based on outcomes, such as fatalities or serious injuries.

In contrast, a reportable aviation incident may occur without any injuries or substantial damage but still requires documentation and analysis because it indicates a breach of safety or operational standards. Incidents can reveal underlying issues that need addressing to prevent future accidents, making them valuable for maintaining safety in aviation.

While the type of aircraft, nature of emergencies, and costs incurred may influence various contexts within aviation operations, they do not fundamentally differentiate between an incident and an accident in terms of regulatory definitions. The focus remains on the severity and outcomes associated with the event, thus underscoring why the severity of the occurrence is the core differentiating factor.
