The CFM International joint venture has been awarded type certificates by the European Aviation Safety Agency (EASA) and the US Federal Aviation Administration (FAA) for its advanced LEAP-1B engine.
The certification enables the engine to enter into commercial service next year.
This January, the LEAP-1B engine flew for the first time on a Boeing 737 MAX aircraft, with subsequent test flights conducted on two more aircraft.
All three aircraft have so far collectively completed more than 100 test flights, including a recent high-altitude flight testing in La Paz, Bolivia.
LEAP-1B engine features several new technologies, including 3D woven carbon fibre composite fan blades and fan case; a debris rejection system; fourth-generation 3D aerodynamic designs; 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.
Compared with other CFM engines, the LEAP-1B engine is expected to provide improvements in fuel consumption and CO2 emissions, as well as reductions in engine noise and gaseous emissions.

By GlobalDataCFM International executive vice-president 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."
As of January, a total of 6,144 LEAP-1B engines had been ordered to power 3,072 MAX aircraft family from 62 customers.
