For an aircraft weighing greater than 2250kg 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: (B)

The main concept is recognizing which events trigger formal reporting when a heavy aircraft is involved. An engine failure, even if the engine is shut down as a precaution, signifies a propulsion system abnormality that directly affects safety and requires immediate notification and investigation by the aviation authority. This kind of propulsion fault is precisely the type of event that regulators want documented to determine causes and prevent recurrence.

The other scenarios don’t fit as straightforward reportable incidents in this context. A missing aircraft can lead to search-and-rescue actions, but it isn’t automatically treated as a reportable incident of the same type unless there’s evidence of an accident. A serious injury on board involves safety concerns, but injuries are usually handled under medical/accident reporting pathways that may be separate from the incident category focused on aircraft system faults. Structural damage that requires major replacement is a maintenance matter and, while serious, is typically recorded within airworthiness and maintenance records rather than as a stand-alone reportable incident under the same criteria.
