The U.S. FAA awarded Part 33 certification to GE Honda Aero Engine's HF120 turbofan engine, certifying its air-worthiness and setting the stage for engine production. The HF120 engine's airworthiness certification follows a ground and flight test program that involved 13 engines. During its certification program, the HF120 engine accumulated more than 14,000 cycles and 9000 h of testing. Assembly is currently under way at GE's facility in Lynn, MA, which is responsible for initial production. Production will transition to the Honda Aero Inc. facility in Burlington, NC, next year. Rated at 2095 lb of thrust, the HF120 engine is designed to set new standards of performance in fuel efficiency, durability, and low noise and emissions.
