US Investigates Chinese Helicopter Engines

Canadian-made engines have been used in China's first domestically developed attack helicopter, according to a 23 October 2007 Reuters story. The PT6 engine was developed over 40 years ago. United Technologies Corp in Canada said that the engines were sold to be used on the civilian version of the aircraft, with a Chinese version to be used in the military helicopters. The Chinese claimed delays in developing their own engine caused the Canadian-built units to be used.
