Orders for CFM Leap engine family accounted for a large portion of the manufacturer's total $51.7 billion in engine sales for 2011.
CFM collected $36.7 billion in Leap orders last year - 930 Leap 1A engines for the A320neo aircraft, which CFM said accounts for 53% of A320neo orders, and 1,896 Leap 1B engines for the Boeing 737 Max. CFM retained its exclusivity as the lone engine supplier for the 737 Max, and competes with the Pratt & Whitney 1100G engines.
CFM also listed nine unnamed customers in its year-end tally for Leap 1B powerplants, joining four customers that have publicly committed to the engine - American, Aviation Capital Group, Lion Air and launch customer Southwest Airlines.
Eight customers have committed to the Leap 1A powering the A320neo - AirAsia, CIT Aerospace, Garuda, GECAS, ILFC, Republic Airways Holdings, SAS and launch customer Virgin America.
The manufacturer said it secured orders for 230 engines for the Comac C919.
During 2011 CFM garnered orders for 394 CFM56-5B engines and 1,012 for the -7B variant.
CFM achieved its previously announced target of 1,300 engine deliveries in 2011, a 4% increase over the 1,250 delivered in 2010. CFM is targeting an annual build rate of 1,400 engines per year by 2014. First deliveries of the C919 powered by Leap 1C engines are scheduled for 2016.
CFM remains bullish on bolstering its Leap customer portfolio this year. "We are expecting additional A320neo, 737 Max and C919 announcements in the next couple of months, so 2012 is already off to a very good start," said company CEO Jean-Paul Ebanga.
