4.4.2 Visual and dimensional examination of cut parts. Inspection shall be made during the
manufacturing process to determine whether cut lengths and sizes of cut parts of the components in
Table V conform to the applicable dimensional requirements as specified in the drawing or part
number. In addition, inspection shall be made during the manufacturing process to ensure that
holes pre-punched in textile and leather components for installation of snap fasteners meet the
requirements of the tolerances referenced in the following Drawings 8-2-601, 8-2-602, 8-2-603, 8-
2-604, 8-2-605, 8-2-606, 8-2-615, 8-2-616, & 8-2-618 and that application of adhesives where
required is uniform. In-process inspection of cut parts shall be performed on the individual layers
that will be used to form an assembled preform and also on preform assemblies before molding to
verify compliance with Government approved method per Drawing 8-2-661 and the requirements
specified in 3.6.1.1.1 or 3.6.1.1.2 as applicable. Whenever nonconformance is noted, corrections
shall be made to the affected parts and in-process lot. Components that cannot be corrected shall
be removed from production.

4.4.2.1 In-process helmet construction inspection. Inspection shall be made during the
manufacturing process to verify that all materials, dimensions, and processes on the drawings
specified in 3.6 are adhered to and comply with all contract and QALI requirements
4.4.2.2 Visual examination of helmet shell prior to finishing (immediately off the mold).
Every helmet shell prior to the finishing operation shall be examined for any evidence of a blister
or delamination. Any blister or delamination, as well as any evidence of a blister or delamination
that was modified by any means after molding (see 3.6.1.2), shall be classified as a defect and the
shell shall be rejected. The Government may verify the results of the contractor's examination by
100 percent examination or by sampling inspection. The Government shall reject the lot
immediately when one defective helmet shell is found.
4.4.2.3 Dimensional examination of helmet shell production lots after drilling of holes. The
helmet shell shall be examined to determine if: the shell thickness 1/; hole locations 2/; hole
diameters, peripheral contour 3/; and inside, height dimensions 4/ conform to the dimensional
requirements specified on Drawing 8-2-830. Any of these dimensions exceeding the specified
tolerance shall be classified as a defect 5/. The lot shall be expressed in units of helmet shells of
