United Technologies Corp and two of its subsidiaries sold China software enabling Chinese authorities to develop and produce their first modern military attack helicopter, U.S. authorities said June 28. At a federal court hearing in Bridgeport, Connecticut, United Technologies and its two subsidiaries, Pratt & Whitney Canada and Hamilton Sundstrand Corp, agreed to pay more than $75 million to the U.S. government to settle criminal and administrative charges related to the sales. As part of the settlement, Pratt & Whitney Canada agreed to plead guilty to two federal criminal charges — violating a U.S. export control law and making false statements. The charges were in connection with the export to China of U.S.-origin military software used in Pratt & Whitney Canada engines, which was used to test and develop the new Z-10 helicopter. Also as part of the deal, United Technologies and Hamilton Sundstrand admitted to making false statements to the U.S. government about the illegal exports. Hamilton Sundstrand and Pratt & Whitney Canada also admitted they failed to make timely disclosures, required by regulations, to the U.S. State Department about the exports.
