Which change requires a technical review according to the Navy Maintenance guidelines?

A technical review is specifically required for Category B FBR (Field Bulletin Report) changes according to Navy Maintenance guidelines. These changes typically involve modifications that may affect the operational capability or safety of equipment and systems. The technical review ensures that any alterations are assessed for their impacts on performance, reliability, and overall effectiveness, maintaining the integrity of the Navy's equipment management and maintenance processes.

In contrast, administrative updates, routine scheduling updates, and general supply requests do not necessitate such a comprehensive review. These types of changes generally pertain to logistics and management rather than technical specifications or capabilities, and thus they can be handled through standard operational procedures without the need for an extensive technical evaluation. This distinction is crucial for maintaining focus on changes that could have significant implications for Navy operations.
