Transportation Partners, the leasing division of Indonesia carrier Lion Group, on Wednesday signed the largest deal so far at the 2016 Singapore Airshow when it gave CFM International a $4.9 billion contract for Leap-1A engines. The turbofans will power 174 Airbus A320neo aircraft ordered back in March 2013.

CFM is helping Lion Group to establish a new engine maintenance and test cell facility in Bantam, Indonesia. The new center will support the CFM56 and Leap engines in the carrier’s fleet. Lion Group has been a CFM customer since 2000 and its entire single aisle narrowbody fleet of 642 A320s and Boeing 737s is powered by CFM engines.

"This is a great extension of the partnership we have built with CFM over the past 15 years," said John Duffy, chief operating officer of Transportation Partners. "In addition to the world-class operating economics and reliability that the Leap engine will bring to our fleet, Leap's strong footprint in Asia and the impressive strides it has made in North America and Europe augments well with our strategic growth objectives.
