All Boeing 737 MAX models are powered by the CFM International LEAP-1B engine, specifically developed for this aircraft family. This engine was designed to provide greater fuel efficiency, lower carbon emissions, and quieter performance compared to the previous generation engines (CFM56 used on 737 NG). Key Features of the LEAP-1B Engine: • Thrust: Ranges from 23,000 to 28,000 pounds, depending on the model (MAX 7, 8, 9, or 10). • Fan Diameter: 69.4 inches (176 cm), larger than the CFM56. • Adva

LEAP (Leading Edge Aviation Propulsion) engines are setting a new standard in utilization, reliability, and performance. The LEAP engine is the culmination of cutting-edge technology and unparalleled performance. Aerodynamically efficient: The LEAP engine fan blades are manufactured from a carbon fiber composite, an industry first. This technology resulted in fan blades that are not only light in weight, but also so durable that each individual blade is strong enough to support the weight of a w
