China Aircraft Leasing Co. (CALC) chose CFM56-5B engines to power 25 new Airbus A320 aircraft. The firm order is valued at $500 million at list prices with deliveries scheduled from 2014-2016.

“We believe that forming this strategic partnership with CFM will be instrumental in helping us expand our business globally,” CALC CEO Mike Poon said.

The 25 A320s are part of a previously announced order for 36 A320 family aircraft in July 2012. They will initially be placed with Chinese lessees, though CALC noted it intends to expand into the rest of Asia and build a presence in Europe and the US.

CFM International said its CFM56-5B has been chosen to power nearly 60% of all A320 aircraft in service or on order. Two engines are available for A320 aircraft; the CFM56 and the IAE V2500.
