In place of normal sampling and inspections associated with the Classification of Defects, and after a c

30、uring time for the parts has been approved (See Note 1). The contractor may, with the approval of the Government, select a sample of three (3) parts (as molded) from each cavity to be fully inspected dimensionally (all dimensions on drawing) to qualify a new or reworked cavity for use in production.

31、 The molded parts shall carry the individual cavity identification. As a control of each cavity during production, the above quantity of parts from each cavity shall be inspected for at least the defects listed in paragraph 4.4.2.1 after continuous production of each 5,000 parts or at the end of eac

32、h week, whichever occurs first. Of the three (3) samples, one (1) sample shall be the last part produced. If any defective parts are found during qualification of the cavity, the cavity producing the defective part will not be used in production. If any defective parts are found when inspection is p

33、erformed for the control of the cavity, the cavity producing the defective part shall be removed from production. Further, that portion of production since the last control check shall be returned to the contractor for inspection for each separate type of defect according to MIL-STD-105, using an AQ

34、L of 0.40 percent for each major defect and an AQL of 0.65 percent for each minor defect. cavities removed from production because of some fault, may after reworking, be returned to production providing they pass the qualification test above.
