What type of change does the Advance Change Notice (ACN) NOT typically cover?

The Advance Change Notice (ACN) typically serves as a formal communication tool used within the Navy's Maintenance & Material Management system to announce upcoming changes to procedures, schedules, and requirements related to maintenance and operations.

Personnel training changes are usually managed through separate channels and are not the primary focus of an ACN. Instead, the ACN is primarily intended to inform personnel about specific alterations in technical publications, Planned Maintenance System (PMS) schedules, emergency maintenance procedures, and scheduled inspections. These changes often directly impact maintenance tasks and operational readiness, which are critical for the efficient functioning of naval activities.

The nature of the ACN is to streamline and organize changes that affect how maintenance is carried out, whereas personnel training changes might be addressed through training programs or specific directives tailored to educational requirements. Thus, focusing on maintenance-related issues while excluding purely training-related changes aligns with the purpose of the ACN.
