Chinese carrier Spring Airlines is to fit 60 Airbus A320neo-family jets with the CFM International Leap-1A powerplant.
Spring disclosed that it had signed for 45 A320neo and 15 A321neo jets in late 2015.
Airbus has not listed these jets – due for delivery from 2019-23 – in its order backlog against the carrier, but attributed an identical order to an undisclosed customer in May 2016.
But CFM has stated, during the Paris air show, that the airline has chosen the Leap engine for all 60 aircraft, valuing the deal at $1.7 billion.
Spring is a strong CFM customer with some 70 CFM56-powered A320s in its fleet.
