Maintenance and Material Management (3-M) 304 Practice Exam

The Advance Change Notice (ACN) is the correct answer because it serves as an official document that signals and initiates changes to existing procedures or documentation, such as the Maintenance Index Page (MIP) or the addition of new Maintenance Requirement Cards (MRCs). The ACN outlines the specific changes required, ensuring that all stakeholders are informed and that proper protocol is followed, maintaining the integrity and accuracy of maintenance documentation.

The other options, while related to maintenance processes, do not specifically focus on authorizing changes to the MIP or the creation of new MRCs. For instance, a Maintenance Action Request typically addresses specific maintenance tasks or corrective actions rather than broad documentation changes. A Change Request Document may request alterations, but it does not carry the same authority or specificity regarding maintenance documentation as the ACN. A Technical Change Notice might inform about technical alterations, but again, it does not centrally deal with documenting those changes in a way that directly modifies maintenance records like the ACN does.
