8.2 MIL - STD - 470

This standard provides requirements for establishing a maintainability program and guidelines for the preparation of a Maintainability Program Plan.

The following tasks are required to be incorporated into the Maintainability Program:

1. Prepare a maintainability program plan.

2. Perform maintainability analyses.

3. Prepare inputs into the detailed maintenance concept and detailed maintenance plan.

4. Establish maintainability design criteria.

5. Perform design trade-offs.

6. Predict maintainability parameter values.

7. Incorporate and enforce maintainability requirements in subcontractor and vendor contract specifications.

8. Integrate other items.

9. Participate in design reviews.

10. Establish data collection, analysis and corrective action system.

11. Demonstrate achievement of maintainability requirements.

12. Prepare maintainability status reports.

8.3 MIL - STD - 471

This standard provides procedures and test methods for verification, demonstration, and evaluation of qualitative and quantitative maintainability requirements. It also provides for qualitative assessment of various Integrated Logistic Support factors related to, and impacting, the achievement of maintainability parameters and item downtimes, such as technical manuals, personnel, tools and test equipment, maintenance concepts and provisioning.
