50 million flight hours: US firm’s plane engine hits milestone, offers 99.98% dispatch reliability

An Ohio-based aircraft engine-maker has achieved a key milestone. GE Aerospace’s GEnx-1B engine has now surpassed the 50 million flight hour mark in just over 14 years. This is claimed to be the fastest rate ever for GE Aerospace’s commercial widebody engine model. The GEnx-1B powers the Boeing 787 Dreamliner family and the engine is currently in service with more than 50 operators around the world, averaging a total of over 600,000 flight hours monthly. Engine boasts a 99.98% dispatch reliability The company claims that the engine boasts a 99.98% dispatch reliability rate and stays on-wing at a rate three times higher than competing engines.“Airlines need engines that deliver reliability, durability, predictability, and efficiency across some of the world’s most demanding routes, and the GEnx-1B continues to do exactly that,” said Mohamed Ali, President & CEO, GE Aerospace Commercial Engines & Services. “Reaching 50 million flight hours for the GEnx-1B in less than 15 years is a remarkable milestone, and it reflects the trust our customers place in GE Aerospace every day.” Long-haul flights the GEnx engine powers traverse some of Earth’s harshest environments The GEnx engine family has more than 2,700 engines in service, including spares. The GEnx-2B has accumulated 24 million hours since entering service in 2011 on the Boeing 747-8. In total, the GEnx engine family has nearly 75 million flight hours and nearly 12 million cycles. The long-haul flights the GEnx engine powers traverse some of Earth’s harshest environments, according to a press release.Over the last decade, GE Aerospace has upgraded the GEnx engine’s high-pressure turbine blades and combustor coating technology, more than doubling time on wing in harsh environments, as per the release.As the fastest-selling widebody jet engine in GE Aerospace history with more than 3,000+ engines in-service and on order, the GEnx delivers proven performance for the Boeing 787 Dreamliner and Boeing 747-8, according to the company.With its superior efficiency, the GEnx powers many of the longest 787 Dreamliner routes, including Qantas’s 787-9 recording-breaking nonstop flight from New York to Sydney. The milestone also reinforces GE Aerospace’s commitment to supporting Boeing’s planned increase in 787 Dreamliner production. Company executives have stated that engine deliveries are rising in line with Boeing’s production goals, ensuring sufficient supply as airlines continue expanding their long-haul fleets. As international air travel continues to grow, the GEnx-1B’s latest achievement highlights the increasing importance of engine reliability, durability and operational efficiency in shaping the future of commercial aviation. For airlines operating demanding long-distance routes, the engine’s record of performance provides a strong foundation for the next phase of global fleet expansion. GE continues to introduce advanced maintenance technologies, including digital inspection tools and enhanced engine cleaning solutions, aimed at improving operational efficiency for airline customers.
