Sikorsky Aircraft and Changhe Aircraft Industries Corp. signed an agreement for Changhe to produce S-76D commercial helicopter cabins. The S-76D helicopter is Sikorsky's newest aircraft. Changhe had previously provided cabins for the predecessor S-76C++ helicopter under an agreement signed by the two companies in 2007. Changhe will now serve as a second source for S-76D cabins, with deliveries scheduled to begin in 2016 and production volume based on market demand. Aerodochody in the Czech Republic also supplies the cabins. Changhe Aircraft Industries Corp. is a subsidiary of China's AVIC, which is a shareholder in the Shanghai Sikorsky civil aerospace joint venture company.
