Which TO update changes data in the basic TO without replacing existing pages?

• A. Supplement
• B. Change
• C. Revision
• D. Amendment

Answer: (A)

Updates to a Technical Order come in several forms. A supplement adds new data to the basic TO without replacing existing pages, so the original material stays intact while new information is added as insert pages or addenda. This is exactly what’s needed when you need to bring in fresh data, procedures, or notes without rewriting or discarding the current content. Other update types involve altering or replacing content—changes modify existing pages, revisions roll out broader updates across sections, and amendments make targeted modifications that usually replace pages. So when the goal is to expand the TO with new information while keeping the current pages in place, a supplement is the appropriate choice.
