If a pilot lands an aircraft with the landing gear not engaged, are they required to report this?

The correct answer asserts that a pilot is not required to report a landing incident without substantial damage, even if the landing gear was not engaged. In aviation regulatory context, an accident is defined as an event leading to serious injury, loss of life, or substantial damage to the aircraft. If a pilot executes a landing without the landing gear but does not incur significant damage to the aircraft or injuries to individuals, it does not meet the criteria for a reportable accident per the Federal Aviation Administration (FAA) guidelines.

This determination is crucial because it highlights the nuances in what constitutes an aviation accident. Insignificant incidents that do not result in safety hazards, injuries, or material damage typically do not require mandatory reporting. The other options, while they address aspects of the situation, do not align with the regulations concerning reportable events in aviation. Reporting pilot error, for example, is important for safety and training but is not a requirement unless there is evidence of accidents or incidents that compromise safety. Thus, the essence of the correct answer lies in understanding the regulatory framework surrounding incident reporting in aviation.
