Pratt & Whitney Canada was charged in Connecticut federal court Thursday for illegally selling advanced helicopter engine technology to China in violation of U.S. arms export laws.
The company was also accused of making false statements to the government during the investigation.
One source said the parts illegally sold were used to help China build an advanced attack helicopter.
"This case is a clear example of how the illegal export of sensisitve technology reduces the advantages our military currently possesses," said Immigration and Customs Enforcement Director John Morton.
John Moran, a spokesman for parent company United Technologies, based in Hartford, Conn., declined comment.
United Technologies Corporation and its subsidiaries Hamilton Sundstrand Corporation and Pratt & Whitney Canada have agreed to pay more than $75 million as part of a global settlement with the Justice Department and the State Department.
A Justice Department spokesman declined comment.
