What must aircraft maintenance records include regarding life-limited parts?

The correct response emphasizes the necessity for maintenance records to include the current status of life-limited parts associated with the airframe, engine, and appliances. This is crucial because life-limited parts are components that have a predetermined lifespan, at the end of which they must be replaced to ensure the safety and airworthiness of the aircraft. The documentation of their current status helps flight crews and maintenance personnel track when these parts need replacement and maintain compliance with regulatory requirements.

By maintaining accurate records regarding the status of these parts, aircraft operators can enhance safety, ensuring that life-limited components are replaced before they reach their limit. This also aids in establishing a reliable maintenance history and in planning future maintenance activities effectively. The other options, while important aspects of maintenance documentation, do not specifically address the critical nature of life-limited parts and their need for continuous status monitoring.
