5、roved 16 August 2001 American National Standards Institute Abstract This AlAA standard establishes a parts management approach that is consistent with todays business environment. This Recommended Practice, as viewed by industry and government, is a shift in business philosophy from a controlled app
6、roach to a performance-based process. The dynamic growth of the commercial market for electronic parts as well as corresponding decrease in aerospace and defense have caused the government and industry to seek alternative methods of managing parts. To develop a solution to this complex problem, indu
7、stry and government teamed to develop this Recommended Practice for mitigating potential problems/risks. The result of this team effort is a non-government standard (NGS) on Parts Management. The basic strategy employed by this document is to understand and manage risk as early as possible in progra
8、m life cycle. Reproduced By GLOBAL ENGINEERING DOCUMENTS Wit The Permission of AIAA Under Royalty Agreement All rights reserved ANSI/AIAA R-l00A-2001 American National standards developer.

27、s part of its Standards Program. In 1995, an industry organized consortium took the initiative to respond to a critical need and then approached the AIAA to achieve broader circulation and demonstration of consensus. In 1996, the document was proposed as an IS0 International Standard within IS0 TC20
28、/SC14, Space Systems and Operations. Publication of that effort is imminent, but the scope is restricted to electrical, electronic, and electromechanical (EEE) parts used in space systems. This 2001 revision draws from the improvements made during the international discussions, but maintains the bro
29、ad application to mechanical parts, as well as EEE and in a broader industry setting. The data in Section 1 has also been brought up-to-date. The Department of Defense (DoD) has adopted this Recommended Practice informally through its acquisition reform program. The challenge to the aerospace and de
30、fense industry during the on-going, changing business environment still calls for the use of performance and commercial specifications with a baseline that ensures the performance, reliability, cost competitiveness, life-cycle projections, on-time delivery, manufacturing process controls, and long-t
31、erm viability of parts and materials. The original industry/government Part Acquisition Reform Team (PART) that developed this perormance- based Recommended Practice to replace military specifications for parts and materials management is maintaining it. The Al AA Standards Program Procedures provid
32、e that all approved Standards, Recommended Practices, and Guides are advisory only. Their use by anyone is entirely voluntary. There is no advance agreement to adhere to any AIAA standard publication and no commitment to conform to or be guided by any standards report. In formulating, revising, and
33、approving standards publications, the Committees on Standards are responsible for protecting themselves against liability for infringement of patents or copyrights or both. This AIAA document is a voluntary standard. It becomes binding only when two parties agree to use it or parts thereof in a cont
34、ract. The AIAA Reliability Committee on Standards, including the Part Acquisition Reform Team, composed of the following individuals, approved the revision in April 2001 : John P.

38、ction 1.1 Scope This Recommended Practice is a collection of techniques for managing parts programs. It addresses the preferred program elements adopted by the aerospace industry (military, civil, and commercial) for parts management. The approaches cover electrical, electronic, and electromechanica
39、l (EEE) and mechanical parts. This document is written in general terms as a baseline for implementing a parts management program. It may be cited as a baseline within a statement of work and/or for assessing proposals and contractor performance. All levels of contractual relationships (acquiring ac
40、tivities, primes, subcontractors, and suppliers) may use this document. EEE and mechanical parts, together with materials and processes, form one of seventeen critical processes involved in the various phases of every program. 1.2 Purpose The purpose of this Recommended Practice is to assist contrac
41、tors in the development of a parts man- agement plan. The user is responsible for integrating the elements of this Recommended Practice appropriate to the program. 1.3 Background Diminishing sources of military and space parts are leading to the use of commercial parts which will result in substanti
42、al nonrecurring engineering (NRE) cost increases in current and future programs. The cost increases are incurred due to the need to establish a new reliability baseline through design, redesign, or modification of current systems, analysis, and test of systems and subsystems utilizing these commerci
43、al parts. The availability of radiation-tolerant/hardened parts is most at risk. The trend of technology obsolescence and diminishing manufacturing sources of military and radiation- hardened parts, materials, and equipment has been rapidly escalating due to a relative decline in the de- fense marke
44、t coupled with the explosive growth of the commercial marketplace. Within the microcircuit industry, for example, military sales have declined from 17 percent to less than 1 percent of the total market (Figure 1). This shrinking market has prompted an increase in the number of products discontinued
45、each year (Figure 2). As a result, industry has increasingly focused attention on issues of parts obsolescence affecting current development and production programs. Life cycles of new microcircuit technologies are rapidly shrinking (Figure 3) and, in some cases, they are shorter than the time it ta
46、kes to get a program through development into production.
