What must the approving person enter in the maintenance record after maintenance or alteration?

After maintenance or alteration, the approving person must enter a description of the work performed along with various details such as the date of the maintenance and the signature of the person approving it. This requirement ensures that there is a clear and comprehensive record that documents exactly what maintenance was completed, providing accountability and traceability. Including the date helps to establish a timeline for the maintenance history, which is crucial for both operational safety and compliance with regulatory requirements. The signature signifies that the work has been reviewed and approved, confirming that it meets the necessary standards and regulations.

While other choices may seem relevant, such as listing personnel involved or the future maintenance schedule, they do not capture the essential requirement for thorough documentation of the work performed and its approval, which is critical for maintaining safety and regulatory compliance in aviation maintenance.
