4.2.1.2  Examinations.  Visual, dimensional, and primary functional examination shall consist of examination of the vehicle for conformance to the applicable drawings and this specification.  Examination shall be performed against the classification of defects and with the acceptable quality levels shown in Table IX and Table X.  The following constitutes a part of the classification of defects (see 6.4 and 6.5)
