Which document provides step-by-step instructions for accomplishing assigned maintenance?

The Maintenance Requirement Card (MRC) is the document that provides detailed step-by-step instructions for carrying out assigned maintenance tasks. Each MRC outlines specific procedures designed to ensure that maintenance is performed consistently and correctly, detailing the required tools, materials, and safety precautions, along with the expected outcomes.

MRCs are crucial for maintaining equipment reliability and operational readiness, as they provide a standardized method to complete maintenance activities while emphasizing safety and efficiency. They serve as a key component in the Planned Maintenance System (PMS), ensuring that personnel have clear guidance on how to perform their duties effectively.

The other options include the Planned Maintenance System (PMS), which encompasses the entire framework for maintenance management, the List of Effective Pages (LOEP), which tracks the current effective versions of maintenance documentation, and Work Authorizations, which are related to the approval and scheduling of maintenance tasks but do not provide the actual step-by-step instructions like the MRC does.
