GE90-94B base engine surpasses 10 million flight hours

The GE90-94B base engine has surpassed 10 million flight hours. “The GE90 engine has surpassed our expectations for performance and reliability, and we look forward to more continued success in the years ahead” said Tom Wygle, general manager of the GE90 Program.

In 1995, the first GE90 engine entered service with British Airways and was the first commercial engine to use composite fan blades. Two years later, GE introduced a growth version of the engine, capable of achieving up to 90,000 lbs. of thrust. The GE90-94B entered service in 2000 with advanced 3-D aerodynamic design in the high pressure compressor. The engine provided customers with a 1.6 percent fuel burn advantage and an approximately 20 degrees Celsius increase in exhaust gas temperature margin for better levels of performance, longer time on-wing and reduction in operating costs. Many customers have upgraded their lower thrust GE90 models to take advantage of these benefits.
