For an aircraft weighing more than 2250 kg which of the following constitutes a reportable aircraft incident?

• A. the aircraft is missing
• B. engine fails and is shut down as a precautionary measure
• C. a person sustains a serious injury on board
• D. structural damage results in major replacement on the affected component

Answer: (A)

The main idea here is knowing what events automatically trigger a reportable incident for a heavy aircraft. When an aircraft goes missing, there’s no way to verify its location, condition, or safety of the occupants, which creates an immediate and unresolved safety concern. That uncertainty requires urgent notification to the appropriate aviation authorities and activation of search-and-rescue procedures. Because of the potential risk to lives and property, a missing aircraft is treated as a reportable incident in standard dispatch practice.

The other scenarios describe situations that, while serious, are not automatically categorized as reportable incidents in this context. An engine failure with a precautionary shutdown may be managed through normal safety procedures if there’s no actual damage, injury, or loss of the aircraft. A serious injury on board or structural damage with major component replacement would usually trigger separate safety and maintenance reporting processes, but they do not carry the same immediate, unaccounted-for-status risk as a missing aircraft.
