1/ If the manufacturer can demonstrate that these tests have been performed for five consecutive
times with zero failures, these tests, with the approval of the quality activity, can be deleted. The
manufacturer, however, shall perform these tests every three years after the deletion as part of
long term design verification. If the design, material, construction or processing of the part is
changed, or if there are any problems, the qualifying activity may require resumption of the
specified testing. Deletion of testing does not relieve the manufacturer from meeting the test
requirement in case of dispute.
4.7.6 Noncompliance. If a sample fails to pass group C inspection, the manufacturer shall immediately
notify the qualifying activity and the cognizant inspection activity of such failure and take corrective action
on the materials or processes, or both, as warranted, and on all units of products which can be corrected,
and which are considered subject to the same failure. For ER acceptance and shipment of the product
shall be discontinued until corrective action, acceptable to the qualifying activity, has been taken. For C
level parts, stop shipment may not be necessary depending on the nature of the failure. After the
corrective action has been taken, group C inspection shall be repeated on additional sample units (all
inspections, or the inspection which the original sample failed, at the option of the qualifying activity).
Group A and group B inspection may be reinstituted; however, final acceptance and shipment shall be
withheld until the group C inspection has shown that the corrective action was successful.
