What information is typically found on a Maintenance Requirement Card (MRC)?

The correct answer highlights that a Maintenance Requirement Card (MRC) contains detailed procedures and frequencies for maintenance tasks. MRCs serve as essential documents in the Navy's maintenance procedures system, outlining specific tasks that need to be performed, including the exact step-by-step processes involved in completing those tasks and the schedule for their execution. This information ensures that personnel are aware of what needs to be done, how to do it, and when it should be carried out to maintain operational readiness and safety.

Other options, while relevant to maintenance operations, do not directly pertain to the information typically found on an MRC. A list of personnel assigned to maintenance tasks is generally found in a different document or system, focusing on crew responsibilities rather than the specific maintenance actions. An inventory of spare parts is managed through separate inventory control processes and systems, which track the availability of parts but do not fit within the scope of MRCs. Similarly, annual training schedules for maintenance personnel pertain to training management rather than the execution of maintenance tasks themselves, thus falling outside the core purpose of an MRC.
