MIL-I-8500D 25 March 1980 Superseding MIL-I-8500C 5 November 1971 MILITARY SPECIFICATION INTERCHANGEABILITY AND REPLACEABILITY OF COMPONENT PARTS FOR AEROSPACE VEHICLES This specification is approved for use by all Departments and Agencies of the Department of

2、Defense 1. SCOPE 1.1 Scope. This specification establishes the dimensional inter- changeability and replaceability requirements for certain parts, subassemblies, assemblies, units, sets, and installation provisions for aerospace vehicles (see 6.1), as listed herein, and which are controlled items as

3、 defined in paragraph 6.2.2. This specification applies to the aerospace vehicle and other elements as may be defined herein, which are peculiar and must be integrated to pro- vide an operational weapon capable of effectively meeting the established performance requirements. These requirements are e

4、stablished to provide or promote easy and rapid assembly of controlled items manufactured by one or more sources, minimize logistic requirements, assure usable parts; and conserve resources. It is mandatory that interchangeability in accordance with this specification shall be a design requirement d

5、uring development of an article. This specification shall be strictly complied with when incorporated (a) into any production contract for aerospace vehicles, and (b) into any aerospace vehicle development contract when such development will proceed to production, unless otherwise specified in any s

6、aid contract. 1.2 Classification. Interchangeability and replaceability as defined and specified herein shall be indicated for a specific article in terms of Interchangeability-Replaceability Working Lists. 2. APPLICABLE DOCUMENTS 2.1 The following documents of the issue in effect on the date of inv

9、iations, and Waivers (Copies of specifications and standards required by contractors in connection with specific procurement functions should be obtained from the procuring officer.) 3. REQUIREMENTS 3.1 Interchangeability and Replaceability. This specification sets forth certain controlled parts, su

10、bassemblies, assemblies, units, and sets (as defined in MIL-STD-280), installation provisions for equipment, major and minor segments of the airframe manufactured separate for later assembly or mating, for which interchangeability and replaceability as defined is required. 3.2 Working lists. Working

11、 lists of such controlled items listing part numbers, nomenclature, and proposed status of the items, shall be complied by or under the supervision of the prime design contractor and submitted progressively to the procuring activity, beginning prior to preliminary fabrication of production tools and

12、 items, for review and evaluation. The complete working list shall be submitted to the procuring activity for approval on a semi- annual basis and after all controlled items therein, subject to first article inspection (see 4.3), have been certified, and shall be approved prior to acceptance of the

13、first aerospace vehicle. The working lists, after approval by the procuring activity, shall reference this specification and shall be considered as meeting the specific requirements of paragraph 3.3.1 and 3.3.2 thereof, and shall be incorporated by reference in the set of engineering drawings (see 3

14、.4) and contract specifications defining the aero- space vehicle configuration. Working lists shall be kept current, during the extent as specified in paragraph 3.5, reflecting design changes, additions, deletions, and aerospace vehicle effectivity serial numbers. Revisions shall be limited to affec

15、ted pages only and there shall be no reissue of existing pages with date change only. 2 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-I-8500D 3.2.1 Forms. The working list pages, listing controlled items, shall be prepared on contractor furnish

16、ed forms in a format con- forming to Figure 1. Requests for additions, changes, and devia- tions to specification requirements, shall be prepared on con- tractor furnished forms in a format conforming to Figure 2. The size of all working list pages shall be comparable to either 8% x 11 or 11 X 17 in

17、ch size and shall be kept uniform throughout any current working list. 3.2.2 Contents. The contents of the working list shall include, but not be limited to; a preface, an index list of page numbers, and pages listing items controlled. The preface shall identify the contractor and location, contract

18、 number, type/model/series of aerospace vehicles with serial numbers assigned, I supported by drawings, sketches, diagrams, and interface data, as applicable; and identification of special tools for installation, if required. A statement of general requirements or criteria, e.g., “aerodynamic smooth

19、ness requirements“, is not an explana- tory reason why the contractor cannot produce an item to meet that requirement and is not satisfactory for evaluation for approval. When approval for exceptions is requested, the remarks column shall be used to give the following information (as appli- cable):

20、justification as required above; type and amount of rework prior to installation; actual (or estimated) manhour requirements involved in rework; special tools for installation, if required. When prior approval of exceptions has been granted, a reference to the procuring activitys correspondence gran

21、ting approval of exceptions shall be entered in the remarks column. Likewise, references shall be made to the procuring activitys directives to depart from the specification required status. Items required replaceable as defined in paragraph 3.3.2, shall have listed in the remarks column; type and a

24、changes. A new entry, or a previously listed entry which has been changed subsequent to approval of the complete working list, shall be identified by an asterisk. All new entries and changes submitted to the procuring activity for approval (see 3.2.1), may be one or more of the following: change in

25、part number, name, status, effectivity, remarks, or notations of. approval. 3.2.3 Submission. Working lists and changes thereto, furnished in accordance with this specification, shall be subject to ini- tial inspection by the Government quality assurance represent- ative. Obvious irregularities will

26、 be returned to the contractor for correction prior to forwarding to the procuring activity for approval. 3.2.4 Approval. Approval of the working list, including changes to the working list, and approval of exceptions once granted, are subject to review, revocation, and further negotiation at the re

27、quest of the procuring activity as improved tooling techniques, controls, and facilities are established, or as maintenance and logistics experience dictates. Applicable contracts will be reviewed and modified by the parties to incorporate approved changes. 3.3 Controlled items. All controlled items

28、, as defined in para- graph 6.2.2, shall be manufactured in accordance with the prime design contractors engineering data and information, and in strict conformity with all control media established by the prime design contractor, as incorporated into applicable contracts. Subject to the provisions

29、of paragraph 3.6.2, all controlled items coming from any approved source, shall be in the same interchangeable or replaceable status as specified in the prime design contractors approved working list and shall mate with adjacent items furnished by the same source or any other approved manufacturing

30、source. 3.3.1 Interchangeability. Interchangeable controlled items shall comply with the definition established in paragraph 6.2.4. Shimming of an interchangeable item is allowed when approved by the procuring activity, and shall not be justification for class- ifyingan item as replaceable. Only tho

31、se tools generally avail- able to aerospace vehicle mechanics shall be required for instal- lation procedure. (This is not intended to preclude use of special tools, fixtures and other shop aids during original assembly of items in the article). All check installations of controlled items shall prov
