MIL-DTL-13791G
First article inspection shall consist of a comparison examination of materials, dimensions, and finish in
accordance with applicable MS or drawings. Then each part shall be assembled in a distributor assembly
that has successfully completed first article inspections as specified in table IV. The installed ARP shall
then be inspected for first article as a complete assembly as specified in table IV. Approval of the first
article sample by the Government shall not relieve the contractor of his obligation to supply ARPs that are
fully representative of those inspected as a first article sample. Any changes or deviation of the
production units from the first article sample shall be subject to the approval of the contracting officer.

4.4.2 First article inspection failure. Deficiencies found during, or as a result of, first article
inspection shall be cause for rejection of the first article sample until evidence has been provided by the
contractor that corrective action has been taken to eliminate the deficiency. Any deficiency found during,
or as a result of, first article inspection shall be evidence that all items already produced prior to
completion of first article inspection are similarly deficient unless contrary evidence satisfactory to the
contracting officer is furnished by the contractor. Such deficiencies on all items shall be corrected by the
contractor. The Government shall not accept products until first article inspection is completed to the
satisfaction of the Government.
