Comac and Bombardier could eventually modify all four of their commercial aircraft models to create an integrated family, with cockpit commonality for the C919 and CSeries an early focus. Help from Bombardier in development of the Comac C919 could also be part of the potentially far-reaching cooperative relationship that the two companies will explore under a framework agreement signed March 23, says Benjamin Boehm, Bombardier’s VP for international business. Substantive contracts on points of cooperation should appear over the coming year.

The deputy chief of the Royal Australian Air Force had said a C-17 already being built for the U.S. Air Force could be diverted to fill Australia’s requirement. While that seemed to leave open the possibility that Boeing would not get an extra order, a company official confirms that it will.

QUAKE COPING: No aerospace suppliers to Mitsubishi Heavy Industries have reported production difficulties from either earthquake damage or a shortage of electricity, a spokesman for the company says.
