e. early trade studies to evaluate operation and support factors in concert with cost, weight, and performance; and to ensure compatibility between design solutions, support equipment needs, and maintenance concepts; and trade studies to investigate reduction of consequence via new design or backups;
f. a disciplined design and development process scheduled to ensure early evaluation of material characteristics, manufacturing processes, and equipment response to design usage;
g. an integrated analysis and ground test program to evaluate design performance and integrity characteristics;
h. a proactive correction of design deficiencies discovered in analysis, test or demonstration before major economic and/or production commitments are established.
i. controls on manufacturing as required to ensure quality and integrity of hardware throughout production;
j. structured program to guide appropriate preventative maintenance tasks to achieve the desired level of safety and aircraft availability at the most economic cost attainable;
k. development of force management requirements (including maintenance and inspection)
based on the results of the development process; and
l. a tracking system to measure actual usage and environment for the fielded equipment, systems and components
1.4 Program overview.
The effectiveness of any military force depends on the mission effectiveness and operational readiness of its weapon systems. A major factor affecting readiness and mission reliability is the integrity (including durability, safety, reliability, and supportability) of the individual systems and equipment comprising the total weapon system. The U.S. Air Force (USAF) adopted the "Weapon System Integrity Process" as the key vehicle to develop, achieve, and maintain required performance economically for the various elements of the weapon system to enhance equipment effectiveness and meet operational needs. The integrity process advocated here was adopted from the highly-successful Aircraft Structural Integrity Program (ASIP) first employed in the late 1950's. This process captures the generic features of ASIP and builds upon the evolution and experiences gained over the last five decades.
The MECSIP description in this standard is intended to illustrate the various tasks required to achieve specific performance and supportability requirements. Although MECSIP is generally applied at the system level, it can and will be tailored for single hardware components. The process described herein must also be tailored and applied to evaluate the capability of existing systems and equipment, including off-the-shelf components.
The MECSIP process consists of a strategy described in the Master Plan that provides mechanical systems and associated equipment with the required integrity throughout the operational service life.
1.5 Applicability.
This standard applies to all systems, equipment, and components whose primary function is mechanical in nature. Examples include: arresting and landing gear (those aspects not already covered by MIL-STD-1530 (i.e., those portions of the landing gear which, if failed, would lead to the inability of the landing gear to safely support the weight of the aircraft during ground
