Requires Department of Defense (DoD) contractors to provide the DoD fair and reasonable access to the repair materials (parts, tools, and information) needed to diagnose, maintain, or repair goods the DoD buys. It allows limited waivers for contracts tied to existing programs if the agency head submits an independent technical risk assessment and justification to congressional defense committees, and it directs a government accountability report on implementation within one year.

Directs the Secretary of Defense to review existing defense contracts to find and propose contract changes that remove intellectual property barriers that prevent DoD maintenance or access to repair materials, and it defines key terms used for parts and tools for both the new access requirement and the contract-review effort.
