What is the document signed by an authorized representative of an approved maintenance organization regarding maintenance performed on a complete aircraft?

The document signed by an authorized representative of an approved maintenance organization regarding maintenance performed on a complete aircraft is known as a Certificate of Release to Service. This certificate is crucial in aviation maintenance as it signifies that the maintenance organization has completed the necessary inspections and repairs in accordance with regulatory standards, and the aircraft is deemed airworthy and safe for operation.

It serves several important purposes: it confirms that all maintenance work has been performed in compliance with required procedures, assures the integrity of the aircraft's systems, and provides a formal acknowledgment that the aircraft is ready to return to service. This document is essential not only for safety but also for legal and regulatory compliance within the aviation industry.

While other options may relate to maintenance documentation, the Certificate of Release to Service specifically denotes the official sign-off that allows the aircraft to be returned to operational status.
