4.5 Nonconformance. If a sample fails to pass group A inspection, the manufacturer shall notify the
qualifying activity and the cognizant inspection activity of such failure, and take corrective action on the
materials, processes, and all units of product, which can be corrected and were manufactured under
essentially the same conditions, and are considered subject to the same failure. Acceptance of the
product shall be discontinued until corrective action acceptable to the qualifying activity has been taken.
After the corrective action has been taken, group B 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 inspections may be reinstituted. However, final acceptance and shipment shall be
withheld until the group B inspection shows that the corrective action was successful. In the event of
failure after reinspection, information concerning the failure and corrective action shall be made available
to the cognizant inspection activity and the qualifying activity.
4.6 Additional QPL test and reporting requirements.
4.6.1 Retention of qualification. To retain qualification, the contractor shall submit a test report to the
qualifying activity at 12 month intervals. The qualifying activity shall establish the initial reporting date.
Each report shall consist of a summary of test and inspection results required by this specification that
were performed during the 12 month reporting interval. As a minimum, the report shall include the
following:
a.
Number of lots produced and tested, including lot and sample sizes for each lot.
b.
Identify which tests were performed.
c.
Quantities passed.
d.
Quantities failed.
e.
All reworked sampling lots shall be accounted for and identified. A summary of corrective
action taken shall be included.
4.6.2 Loss of product qualification.
4.6.2.1 Failure to meet test requirements. The manufacturer shall immediately notify the qualifying
activity at any time during the 12-month reporting period when the qualified product fails to meet the test
and inspection requirements of this specification. The manufacturer shall identify and indicate what
corrective action will be taken to correct the problem. Failure to take corrective action acceptable to the
qualifying activity may result in removal of the product from the QPL.
4.6.2.2 Failure to submit summary test data report. Failure to submit a test report within 30 days
after the end of the 12 month reporting period may result in removal of qualification for the product.
