CFM International, the joint venture between GE Aviation and French company Snecma, said 2012 was one of its best years for production of its CFM56 product line of jet engines.

CFM International is headquartered in West Chester Twp., in Butler County, at GE Aviation’s North Pointe at Union Centre facilities. GE Aviation is headquartered in Evendale, in suburban Cincinnati. Also, GE Aviation has a site in Beavercreek that makes components for the CFM56 engine, such as tubing and ducts.

The jet engine joint venture received orders and commitments last year for $23.5 billion worth of CFM56 engine and LEAP engine related products, CFM International said in an announcement Monday.

The CFM56 engine powers the narrow body jetliners Airbus A320 and Boeing 737.

The LEAP engine is a new engine under development by CFM International that will come to market in 2016, GE Aviation said.

The LEAP engine will power future Airbus A320 and Boeing 737 airplanes, as well as new planes under development — the Airbus A320neo, Boeing 737 MAX and COMAC C919 from China. LEAP is GE Aviation’s biggest development program right now, the company said.

“We are definitely in a mode where we’ve got to expand capabilities,” said GE Aviation spokesman Rick Kennedy.

CFM International recorded 898 new multi-year orders in 2012 for commercial, military and spare CFM56 engines and firm orders. And it actually produced 1,420 CFM56 engines in 2012, the company said.

Last year it also received more than 1,100 new commitments for LEAP engines.

To date, CFM said it has logged total orders and commitments for more than 4,500 LEAP engines. Total CFM56 engine orders stand at nearly 29,300 engines. CFM International formed in 1974.

Plans are to reach production of more than 1,700 engines per year by 2019 as CFM transitions from CFM56 to LEAP engine production.

“CFM56 engine orders continue to be very strong, and we are delighted that customers have embraced the LEAP engine for their next generation of single-aisle aircraft,” said Jean-Paul Ebanga, president and chief executive officer of CFM International, in a statement.
