4.6.5.1 Failures. If a sample fails to pass sampling inspection, see table VII, the manufacturer shall
immediately notify the qualifying activity and cognizant inspection activity of such failure. The
manufacturer shall take corrective action on the materials or processes or both as warranted, on all units
of product which can be corrected and which were manufactured under essentially the same conditions,
with essentially the same materials and processes, and which are considered subject to the same
failure.
4.6.5.2 Acceptance and shipment. Acceptance and shipment of the product shall be discontinued
until corrective action acceptable to the qualifying activity has been taken. After the corrective action has
been taken sampling inspection, see table VII, shall be repeated on additional samples. At the discretion
of the qualifying activity this may included all inspections, or the inspection which the original sample
failed. Individual and sampling and periodic inspections, if applicable, may be reinstituted. However
final acceptance of the hose or hose assemblies shall be withheld until the sampling and periodic
inspection has shown that the corrective action was successful.
4.7 Additional QPL test and reporting requirements.
4.7.1 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.

4.7.3 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.
4.7.4 Failure to submit summary test data report. Failure to submit a report within 30 days after the
end of the 12 month reporting period may result in loss of qualification for the product.
4.7.5 Change to manufacturing process, materials or equipment. The manufacturer shall notify the
qualifying activity, in writing, of any changes in the manufacturing process, materials, or equipment used
to manufacture a QPL product. Subsequently, the qualifying activity will notify the manufacturer, in
writing, if a full re-qualification, partial re-qualification, or no additional testing is required as a result of
these changes.
4.7.6 No production during reporting period (12 months). When no production occurs during the
