Which documents must include the current status of life-limited parts?

The correct response is that aircraft maintenance records must include the current status of life-limited parts. Life-limited parts are components of an aircraft that have a predetermined operational life, which means they must be replaced or overhauled after a specified amount of time or usage. Keeping accurate and up-to-date records of these parts within the maintenance documentation is crucial for safety and compliance with regulatory standards.

Maintaining a clear record allows for effective tracking of the remaining life of these components, ensuring that they are replaced before they reach the end of their safe operational life. This practice also supports the airworthiness of the aircraft and helps to prevent potential failures during operation, enhancing overall flight safety.

While pilot logs document flight time and experience for pilots, and airworthiness certificates assess the overall compliance and safety of an aircraft, they do not focus specifically on the status of life-limited parts. Pre-flight checklists are tools used before flight to ensure that aircraft systems are functioning properly and that nothing is overlooked, but they do not provide ongoing documentation or tracking of life-limited components.
