The process described herein is a "cradle-to-grove" process that is equally applicable to the design phase as it is to the sustainment phase. It applies to new development, modifications, upgrades, and sustainment. It applies equally to both development and non-development items, including commercial off-the-shelf. For development items, the purpose of this process is to establish and sustain a design that meets the service life, mission, usage, and environmental requirements. For non-development items, the emphasis is on definition of the capabilities of the item when subjected to the intended service life, mission, usage and environments. If shortfalls are identified in the existing capabilities of a non-development item, the System Program Office then has the necessary information to initiate the appropriate trades relative to the cost of the design change versus required performance, maintenance actions, total operating cost, impact on mission, etc.

Purpose. The purpose of this handbook is to describe the general process to achieve and maintain the physical and functional integrity of the mechanical elements of airborne, support, and training systems. The goal of the program is to ensure the operational safety, suitability, and effectiveness (OSS&E) of a weapon system, while reducing total operating cost. The process described herein is in direct support of the OSS&E Air Force Policy Directive 63-12 and the Air Force Instruction 63-1201 requirements to establish a disciplined engineering process that will ensure the physical and functional integrity of the system being procured. This handbook allows the process to be tailored in a competitive environment to meet specific equipment, subsystem, and/or system requirements. The Mechanical Equipment and Subsystems Integrity Program (MECSIP) is implemented in the planning process and continued until retirement of the system. This handbook should be tailored for each program in accordance with specific program strategy.

This handbook applies to all systems, equipment, and components whose primary function is mechanical in nature. Examples include these systems: arresting gear, auxiliary power, crew escape, electromechanical elements of electrical power, electrical wiring, environmental control, fire protection, flight control, fuel, ground support, hydraulic, landing gear, life support, pneumatic, training, and maintenance.
