What should be done with the AFTO Form 781 when an aircraft is retired?

• A. It should be destroyed immediately
• B. It should be updated with final data only
• C. It should be archived as part of the aircraft's historical records
• D. It should be filed under current aircraft records

Answer: (C)

When an aircraft is retired, the AFTO Form 781 should be archived as part of the aircraft's historical records. This form serves as a comprehensive record of the aircraft’s maintenance, operational history, and any modifications or incidents throughout its service life. By archiving the Form 781, the historical data can be preserved for future reference, research, or analysis regarding fleet management, safety assessments, or refurbishment of similar aircraft. Retaining these records contributes to the knowledge base and can help inform decisions on aircraft design, maintenance practices, and operational protocols.

Updating it with final data only or filing it under current aircraft records would not provide the necessary documentation for historical purposes, as those options imply temporary or limited usability rather than long-term preservation. Destroying the form immediately would eliminate valuable information that could benefit future planning or operations.
