4.5.6 Retention of qualification. To retain qualification, the contractor shall forward a report at 24-month intervals
to the qualifying activity. The qualifying activity shall establish the initial reporting date. The report shall consist of:
a.
A summary of the results of the tests performed for inspection of product for delivery (group A), indicating
as a minimum the number of lots that have passed and the number that have failed. The results of tests of
all reworked lots shall be identified and accounted for.
b.
The results of tests performed for periodic inspection (group B), including the number and mode of failures.
The test report shall include results of all periodic inspection tests performed and completed during the 24-
month period. If the test results indicate nonconformance with specification requirements, and corrective
action acceptable to the qualifying activity has not been taken, action may be taken to remove the failing
product from the qualified products list.
c.
Design of mixer has not been modified.
Failure to submit the report within 30 days after the end of each 24-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 24-month period that the inspection data indicates failure of the qualified
product to meet the requirements of this specification.
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 24-month reporting periods,
there has been no production, the manufacturer may be required, at the discretion of the qualifying activity, to submit
the products to testing in accordance with the qualification inspection requirements.
