4.4.3 Rejected lot. Failure of any sample to pass any inspection shall constitute a failure of the
lot. If an inspection lot is rejected, the contractor may rework the lot to correct the defects or
screen out the defective units, and resubmit the lot for re-inspection. Such lots shall be separated
from new lots and shall be identified as re-inspected lots (see 4.4.4).
4.4.4 Noncompliance. If a sample fails to pass any inspection, the contractor shall notify the
cognizant inspection activity of such failure and take corrective action on the materials or
processes or both, as warranted on all units of the product. Acceptance and shipment of the
product shall be discontinued until corrective action has been taken. After the corrective action
has been taken, the conformance inspection shall be repeated on replacement articles. (This
includes all tests and examinations, or only the test that the original sample failed, at the option of
the cognizant inspection activity.) Final acceptance and shipment shall be withheld until
inspection has shown that the corrective action was successful. In the event of failure after re-
inspection, information concerning the failure shall be provided to the cognizant inspection
activity.
4.4.5 Group A inspection. This inspection, including sampling, shall consist of visual dimensional
and 3.8 as applicable.
