What must be included in aircraft maintenance records for airworthiness?

The status of life-limited parts must be included in aircraft maintenance records to ensure airworthiness because these parts have a defined operational lifespan and are critical for safe flight operations. Tracking their condition is essential for maintaining safety standards. If these parts exceed their limits without proper inspection or replacement, they may fail, posing serious safety risks. Therefore, maintaining an accurate record of their status helps in adherence to safety regulations and promotes proactive maintenance practices, thereby ensuring that the aircraft remains airworthy.

Other elements such as the owner's contact information, weather conditions during flight, and pilot's flight hours, while important for various administrative and operational reasons, do not directly impact the airworthiness of the aircraft in the same way that the status of life-limited parts does. These records can aid in management and operational oversight but do not provide the necessary insight into the physical condition of the aircraft components that could affect flight safety.
