contract. Sampling inspection, as part of manufacturing operations, is an acceptable practice to
ascertain conformance to requirements, however, this does not authorize submission of known
defective material, either indicated or actual, nor does it commit the Government to acceptance
of defective material.
4.2 Government verification. Quality assurance operations performed by the contractor will
be subject to Government verification at unscheduled intervals. Verification will consist of
observation of the operations to determine that practices, methods, and procedures of the
contractor's inspection are being properly applied. Failure of the contractor to promptly correct
product deficiencies discovered shall be cause for suspension of acceptance until correction has
been made or until conformance of product to specification criteria has been demonstrated.

conducted to evaluate workmanship and to determine conformance to structural requirements.
The vehicle shall be tested in accordance with 4.3.2.1 through 4.3.2.3 prior to prime painting,
and dye penetrant or magnetic particle testing shall be performed on all critical areas to inspect
for crack indications under dynamic and static conditions. Any evidence of cracks or permanent
deformation shall be cause for rejection of the vehicle.
4.3.2.1 Dynamic conditions. With the test load specified in table V, the body shall be raised
and lowered for at least 1/2 hour while being inspected for cracks and permanent deformation.
4.3.2.2 Static conditions. With the body in its highest position, three times the payload
specified in table II for classes A, B, and C and two times the payload for classes D and E shall
