What is the function of the Maintenance Requirement Card (MRC)?

The Maintenance Requirement Card (MRC) serves a critical role in the maintenance management process by specifying the maintenance actions that need to be performed on equipment. MRCs provide detailed instructions regarding the specific tasks that technicians must complete, including procedural steps, tools required, and the frequency of maintenance activities. This structured approach ensures that all necessary maintenance is conducted consistently and safely, following established guidelines to uphold equipment reliability and performance.

While it may seem useful to track equipment degradation, log equipment history, or record daily operations, these functions are not the primary purpose of the MRC. Instead, the MRC's main focus is on delineating the necessary actions to keep equipment in optimal working condition, thus making it an essential tool for maintenance personnel.
