Maintenance concept establishes requirements and the maintenance plan establishes specific levels of repair.

• A. True
• B. False
• C. Not sure
• D. Not applicable

Answer: (A)

In maintenance planning, the overall maintenance concept sets the requirements for how the system should be supported—defining what needs to be achieved in terms of maintainability, reliability, and availability. The maintenance plan then takes that guidance and translates it into concrete actions, specifying the levels of repair to apply, where those repairs happen (for example, field, intermediate, or depot), and the timing, procedures, and resources needed to meet the concept’s requirements.

So, the statement is true because the concept provides the performance and support requirements, while the plan details the specific repair levels and how to achieve them. The other options don’t fit because they either imply there’s no distinction between concept and plan or misplace what each document establishes.
