Which type of technical order update changes data in the basic technical order without replacing the existing pages?

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

Answer: (B)

A supplement is the type used when you need to add or update data in the basic technical order without replacing the existing pages. It acts as an addendum that brings in new or revised information while the original pages stay in place, so the document remains intact but with updated content. This approach is preferred when changes are needed but don’t require a complete rewrite of the TO. In contrast, a revision replaces pages to deliver a new edition, an amendment typically patches specific content that often involves page replacements, and errata covers small corrections to the published material rather than broad data updates within the TO itself.
