4.4.5 Retention of qualification. To retain qualification, the contractor shall make available to the
qualifying activity a report at 12-month intervals. The qualifying activity shall establish the initial reporting
date. Each report shall consist of the number of lots produced in the reporting period, the quantity of
production in each lot, the tests performed during the reporting period, how many times each test was
performed, the number of samples per test, the number of test samples passing and the number of test
samples failing. All reworked sampling lots shall be accounted for and identified.
4.4.5.1 Removal from QPL. If the summary of test results indicates nonconformance with
requirements specified herein but the corrective measures acceptable to the qualifying activity have not
been taken, action may be taken to remove the failing product from the qualified products list. Failure to
submit the report within 30 days after the end of each 12-month period may result in loss of qualification
for the product. In addition to the periodic submission of inspection data, the contractor shall immediately
notify the qualifying activity at any time during the 12-month period that the inspection data indicates
failure of the qualified product to meet the requirements of this specification.
4.4.5.2 No production. In the event that no production occurred during the reporting period, a report
shall be submitted certifying that the company still has the capabilities and facilities necessary to produce
the item. If during two consecutive reporting periods there has been no production, the manufacturer
may be required, at the discretion of the qualifying activity, to submit his qualified products to testing in
accordance with the qualification inspection requirements specified in table II.
