Powering on: American Airlines selects GEnx engines to power Boeing 787 Dreamliners

April 09, 2018
The fastest-selling, high-thrust jet engine in GE Aviation history, the GEnx, was just again selected to power 47 newly ordered Boeing 787 Dreamliners by American Airlines.

In addition to selecting GE Aviation’s GEnx-1B engines to power its newly ordered Boeing 787 Dreamliners, American Airlines also signed a TrueChoiceTM Overhaul agreement with GE for up to 20 years of maintenance, repair and overhaul for the GEnx-1B engines ordered.

The engine order and TrueChoice agreement is valued at more than $6.5 billion at engine list price and over the life of the Services agreement. The order will increase American Airlines’ GEnx-powered Boeing 787 Dreamliner to 89 aircraft.

“American Airlines helped launch GE’s commercial engine business more than 45 years ago with the CF6 engine,” said Kathy MacKenzie, GEnx general manager at GE Aviation. “This order reaffirms our long-standing successful relationship and demonstrates American’s confidence in the GEnx engine.”

With this order, the GEnx order book rises beyond 2,000 engines sold in less than 15 years since the program was selected to power the Boeing 787 Dreamliner, solidifying it as the fastest selling high-thrust GE engine in history.


With the most advanced technologies and materials, the GEnx has the lowest fuel burn, longest range capable and is the highest reliable engine available on the B787 aircraft. The highest pressure ratio compressor in commercial service today enables the best fuel efficiency in its thrust class, resulting in the GEnx engine powering the longest B787 routes. The GEnx's innovative lean burning twin-annular pre-swirl (TAPS) combustor dramatically reduces NOx and other regulated gases below today's regulatory limits and enhances durability. As the world’s first commercial engine with both a carbon fiber composite front fan case and fan blades, the GEnx fan module is lighter in weight, corrosion resistant with less line maintenance and improved reliability and is the quietest engine GE produces. These leading-edge technologies and engine architecture bring high operational reliability and result in a high utilization rate of GEnx-powered B787 aircraft for more flights per year and more revenue for airlines.

In addition to this most recent deal with American Airlines, the GEnx engine has had a busy year. Check out the latest news and stories about the GEnx engine:

Powering history: GE Aviation’s GEnx engines power the world’s longest Dreamliner flight from Perth to London

GE Aviation is privileged to power the Qantas 787-9 fleet with the GEnx engine and especially the historic flight from Perth to London.  On Saturday evening, March 24, around 236 passengers took part in a major milestone in the aviation industry when QF9, taxied down the runway at Perth airport to take off for the first non-stop passenger flight to London — covering more than 9,000 miles with an approximate duration of 17 hours and 20 minutes.

Big data is everywhere, including aviation.

At GE Aviation, we monitor more than 30,000 commercial engines daily. How much data do we collect? Our engines produce data snapshots at various points in flight, such as take-off, climb and cruise. The snapshots include up to 1,000 different measurement parameters, and each engine can pump out between 50 to 200 megabytes of data per flight depending on the flight time. This gives us a massive amount of data.

The magnitude of manufacturing in the GEnx

It takes more than a village to build a jet engine. In fact, it takes six countries, 12 states and 21 GE manufacturing sites providing 1.1 million total parts to form one GEnx jet engine. With more than 1,600 GEnx-1B engines sold worldwide, that means 1.76 billion parts come together to form the fastest-selling, high-thrust jet engine in GE Aviation history.
