Quality Assurance Committee (QAC)

The QAC's mission is to improve component reliability and durability with the goal of enhancing the safety and operational integrity of interchange freight cars and to reduce the overall cost of equipment maintenance by assuring that both new and reconditioned mechanical components conform to established AAR specifications. The QAC is responsible for developing and maintaining AAR Quality Assurance Specification M-1003 and governing the AAR Quality Assurance Program. The QAC Manager can answer questions concerning AAR's Quality Assurance Program including: auditor accreditation, M-1003 certification, Chapter 7 nonconformance reporting, and M-1003 training seminars.
