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

Aircraft maintenance records must include the current status of life-limited parts of each airframe, engine, propeller, rotor, and appliance because these components have specified operational limits beyond which they should not be used. Tracking their status is crucial for safety and compliance with maintenance regulations, as failing to respect these limits can lead to catastrophic failures during flight. Maintenance personnel and safety officers rely on this information to ensure that aircraft meet airworthiness standards and are safe for operation.

Proper documentation helps in monitoring these parts through their lifecycle, including when they are installed, their usage history, and any replacements that are made. This meticulous tracking also aids in preparing for inspections and audits by regulatory authorities, ensuring that the aircraft remains compliant with applicable aviation safety regulations and standards.
