Approval shall be withheld or withdrawn when there is a recurring noncompliance with requirements, including but not limited to-(1) Certified cost or pricing data (see 15.403);(2) Implementation of cost accounting standards (see 48 CFR chapter 99);(3) Advance notification as required by the clauses prescribed in 44.204; or(4) Small business subcontracting (see subpart 19.7).(b) When approval of the contractor's purchasing system is withheld or withdrawn, the ACO shall within 10 days after completing the in-plant review(1) inform the contractor in writing,(2) specify the deficiencies that must be corrected to qualify the system for approval, and(3) request the contractor to furnish within 15 days a plan for accomplishing the necessary actions.
