The purpose of this memorandum is to notify you that we plan to begin the subject audit in April 2023. The objective of this audit is to determine whether the Air Force has effective controls and procedures to identify and remove from the DoD supply chain defective spare parts provided by contractors and to obtain restitution from the contractors that provided the defective spare parts. We may revise the objective as the audit proceeds, and we will also consider suggestions from management for additional or revised objectives. We plan to perform the audit in accordance with the Government Accountability Office’s generally accepted government auditing standards.
