4.5.15 Verification of safe condition of S&A prior to shipment.
The
S&A's shall be 100% inspected for compliance with the requirements of
3.7
using depth and/or flush pin gages through inspection ports. Any S&A
failing
to conform with the applicable requirement shall be classed defective
and
removed from the lot. (Non-destructive test).
4.5.16 Dimensional control of cast parts. In place of the normal
sampling and inspections associated with the Classification of Defects, and
with the approval of the Contracting Officer, a sample of at least three (3)
parts (as cast) from each cavity shall be fully inspected dimensionally to
qualify a new or reworked cavity for use in production (see Note 1).
Inspection for control of each cavity during production shall be performed on
the above quantities from each cavity after production of 5,000 parts or at
the end of each week, whichever comes first. Individual cavity identification
must be provided.
If any defective parts are found during qualification of the cavity, the
cavity producing the defective part(s) shall not be used in production. If
any defective parts are found when inspection is performed for control of the
cavity, the cavity producing the defective part(s) shall be removed from
production. Further, that portion of production since the last control check
shall be considered defective and shall not be used without verifying that the
parts meet the drawing by inspection for compliance in accordance with the
Classification of Defects.
If any defective parts are found during qualification of the tool, the
tool producing the defective part(s) shall not be used in production.
If any defective parts are found when inspection is performed for control

production. Further, that portion of production since the last control check
shall be considered defective and shall not be used without verifying that the
parts meet the drawing by inspections for compliance in accordance with the
Classification of Defects.
All tools removed from production because of some fault, may, after
reworking, be returned to production providing they pass the qualification
test above. The contractor may request a change of inspection frequency
providing he presents objective evidence to the Contracting Officer to
substantiate the request.
NOTE 1:
Those features of a part which are subsequently machined or
otherwise worked upon to meet its drawing requirements shall be
