Which document provides the step-by-step maintenance procedure?

• A. LOEP
• B. MIPS
• C. PMS Schedule
• D. Maintenance Requirement Card (MRC)

Answer: (D)

The Maintenance Requirement Card provides the step-by-step maintenance procedure. It serves as the hands-on guide for performing tasks, laying out the exact actions to take, the order to follow, required tools, safety notes, torque specs, parts to replace, and any special instructions. Other documents play planning or reference roles—the PMS Schedule shows what needs to be done and when, LOEP lists equipment and its related references, and MIPS is the data system for maintenance information rather than the actual procedures. So the MRC is the best source for the precise procedural steps you follow during maintenance.
