Cologne, Germany and Boston, Massachusetts – CFM International’s advanced LEAP-1B engine was simultaneously awarded type certificates by both the European Aviation Safety Agency (EASA) and the U.S. Federal Aviation Administration (FAA), paving the way for entry into commercial service in 2017.
 
CFM is the only engine manufacturer to gain dual original certification from both agencies, rather one lead agency issuing a type certification and the second agency validating that certification. This reflects CFM’s 50/50 design and production structure between parent companies GE and Safran.
 
“This is another great milestone for the LEAP program and the hard-working team behind it,” said Allen Paxson, executive vice president for CFM. “Everyone, from the project and engineering teams to manufacturing and our suppliers, has done an incredible job of keeping this program on schedule and building an engine that is delivering everything that we have promised.”
 
The LEAP-1B engine flew for the first time on the Boeing 737 MAX on Jan. 29, 2016. Since then, two more aircraft have been added to the test program in March and, to date, these three airplanes have logged a combined total of more than 100 test flights, including completing high altitude flight testing in La Paz, Bolivia.
 
“We couldn’t be happier with the way this engine is performing,” said Francois Bastin, executive vice president of CFM International. “Boeing is racking up an impressive number of flight hours with the test aircraft and initial indications are that engine performance is meeting expectations.”
 
The LEAP-1B engine features some of the industry’s most advanced technologies, including 3D woven carbon fiber composite fan blades and fan case; a unique debris rejection system; 4th generation three dimensional aerodynamic designs; the Twin-Annular, Pre-Swirl (TAPS) combustor featuring additively manufactured fuel nozzles; ceramics matrix composite shrouds in the high-pressure turbine; and titanium aluminide (Ti-Al) blades in the low-pressure turbine.
 
The LEAP-1B engine had been selected to power 3,090 Boeing 737 MAX aircraft from 64 customers. Overall, CFM has received orders for more than 10,500 LEAP engines across all three models.
