This standard describes the Propulsion System Integrity Program (PSIP) and defines the requirements necessary to achieve integrity in propulsion systems while the cost of ownership is minimized; and cost and schedule risks managed through a series of disciplined, time phased tasks. This standard details programmatic tasks for the development, acquisition, and sustainment of propulsion systems to ensure their integrity while affordability of these United States Air Force (USAF) systems is maintained throughout their period of use.
