scope:

This specification establishes the dimensional interchange ability and replacebility 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 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 provide an operational weapon capable of effectively meeting the established performance requirements. These requirements are established 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 iterchangeability in accordance with this specification shall be a design requirement during development of an article. This specification shall be strictly complied with wen 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 said contract.
