shall be corrected by the contractor when found.
4.1.12.6 Recurring minor deficiencies. A minor deficiency is recurring if it occurs more
than twice in the same sample, or when the defect occurs in four successive samples. Recurring
minor deficiencies shall be cause for the entire lot or lots to be inspected for the recurring

4.1.14.2 Failure. If the vehicle selected fails to pass any of the control tests, the Government
inspector shall stop acceptance examination and testing on subsequent vehicles until such time as
