The FAA and European Aviation Safety Agency (EASA) have awarded type certificates to CFM International’s LEAP-1B engine, paving the way for entry into commercial service in 2017. The LEAP-1B engine is the exclusive powerplant for the Boeing 737 MAX.

“The LEAP-1B engine flew for the first time on the Boeing 737 MAX on Jan. 29,” CFM International said in a statement. “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, recently.”

CFM International EVP Francois Bastin said, “Boeing is racking up an impressive number of flight hours with the test aircraft and initial indications are that engine performance is meeting expectations.”
