(CNN) -- A Canadian subsidiary of a U.S.-based multinational firm pleaded guilty in federal court Thursday to illegally sending software to China, which it used in the development of its first advanced attack helicopter, according to the U.S. attorney in Connecticut. Pratt & Whitney Canada -- a subsidiary of Hartford, Connecticut-based United Technologies Corporation -- pleaded guilty to violating the Arms Export Control Act. In a case going back more than a decade, the firm admitted it sold software that was used in the development and testing of the new Z-10 helicopter for China's army. UTC, Pratt & Whitney Canada and another UTC subsidiary -- Hamilton Sundstrand Corporation -- agreed to pay more than $75 million as part of a settlement with the U.S. government because of the arms export violations and for making false statements, according to a statement from U.S. Attorney David B. Fein and other federal officials.
