Pls define it and explain its use using examples. What is the difference between a maintenance item and object list?

Does a maintenance item refer to any "MSIs (which) include systems, subsystems, modules, components, accessories, units, and parts.?

Or does maintenance item refer to MRO items (which) include

  • Oils
  • Lubricants
  • Gloves
  • Safety equipment
  • And cleaning products?

Maintenance Significant Item (MSI)
