units or to require the contractor to furnish the sample units with the qualification inspection report.
4.4.5 Retention of qualification. To retain qualification, the contractor shall verify in coordination with
the qualifying activity the capability of manufacturing products, which meet the performance requirements
of this specification. Refer to the qualifying activity for the guidelines necessary to retain qualification to
this particular specification. The contractor shall immediately notify the qualifying activity at any time that
the inspection data indicates failure of the qualified product to meet the performance requirements of this
specification.
4.5 Conformance inspection.

4.5.1.2.1 100% inspection plan. All units shall be subjected to group A inspection. No failures are
permitted. If one or more units fail, the lot shall be considered to have failed. The lot may be screened
for that particular defect and defects removed. After screening, the lot shall be retested. Any failure in
the screened lot shall constitute failure of the lot and the lot shall be rejected.
4.5.1.2.2 Rejected items. If an inspection item is rejected, the contractor may rework it to correct the
defect and resubmit for inspection. Such items shall be separate from new items and shall be clearly
identified as reinspected items. Even if rejected items are reworked and resubmitted, no more than one
failure in visual/mechanical examination and no more than one subsequent failure in electrical inspections
(VSWR) shall be permitted. When more failures occur, they shall be reported to the qualifying activity
(DSCC-VQE) as indication of process problems and potential threat to product reliability. Subsequent
rejections for the same parameter shall be cause for reinspection of the entire lot.
4.5.2 Qualification verification inspection. Qualification verification inspection shall consist of group B.
Except where the results of these inspections show noncompliance with the applicable requirements (see
4.5.2.1.4), delivery of products which have passed group A shall not be delayed pending the results of
these qualification verification inspections.
