Aircraft Maintenance Records are the documents that backup and support the statement of airworthiness of an aircraft and its component parts. Well organized, easily retrievable, protected maintenance records and documentation not only provide required evidence of the legal airworthiness of the aircraft, but they are required to be comprehensive and thorough in compliance with the FARs.
