AVIC Aircraft will be the second supplier for in-board flaps on the 737 Max, Boeing says in a news release.
The deal announced on 25 October will take effect in mid-2015, or two years before the 737 Max is scheduled to enter service.
Part of the Chinese production of the inboard flaps will take place at the Xi’an Aircraft Company’s manufacturing innovation centre in Beijing.
Boeing partnered with AVIC in 2011 to open the centre in an effort to expand and enhance the supplier’s production capabilities.
Mitsubishi Aircraft is already named a supplier for the inboard flaps of the re-engined and updated 737, too.
AVIC Aircraft is now a supplier to Boeing on the 737 Max, 767 and 747.
The deal surfaces amidst reports that Chinese airlines are set to buy as many as 200 737 Max aircraft worth $20.7 billion.
