Sikorsky Aircraft Corporation makes helicopters and Pratt and Whitney makes aircraft engines. Both companies are wholly owned by United Technologies Corporation. Both have various foreign and domestic military and civilian customers and both sell their products to the U.S. Department of Defense (DoD). The Defense Contract Management Agency (DCMA) an agency within the DoD monitors defense contractors including Sikorsky and Pratt to ensure that they satisfy their contractual obligations when providing services and supplies to the DoD. If the DCMA discovers a problem it notifies the contractor and may issue a Corrective Action Request (CAR) or an audit report to the contractor to remedy the problem.
