Which FAA publication instructs aircraft owners about unsafe conditions?

The correct answer is the Airworthiness Directives. This publication is critical for ensuring safety in aviation, as it provides specific instructions from the FAA regarding known unsafe conditions related to aircraft and their components. When the FAA identifies a safety concern that may affect the airworthiness of an aircraft, they issue an Airworthiness Directive to alert owners and operators.

These directives often contain mandatory actions required to rectify the safety issue, such as inspections, repairs, or alterations, and they may specify a compliance time frame. By following the guidance outlined in Airworthiness Directives, aircraft owners can mitigate risks and maintain the safety and reliability of their aircraft.

While other publications might contain important information regarding aviation maintenance or guidance for aircraft operation, they do not specifically focus on communicating immediate safety concerns related to unsafe conditions as effectively or directly as Airworthiness Directives do.
