The CF6 engine entered service in 1971, with the CF6-6, a 40,000-pound thrust engine that powered American Airlines’ and United Airlines’ DC-10 Series 10 aircraft. This propelled GE into the commercial aviation industry and ushered in high by-pass fan technology, and the powerplant continues to be the cornerstone of the widebody commercial aircraft business.

Remarkably, of the more than 7,000 CF6 engines delivered, nearly 70% are still in service today – and the technology evolution continues.

Continuous enhancements to performance and reliability have delivered customer benefits:

  • An overall 2.7X engine time on wing (TOW) improvement since initial entry into service.
  • 15% Improved fuel burn since the initial CF6 product entry
  • Lower maintenance cost through enhanced materials and technology upgrades

For instance, the latest CF6-80E1 tech insertion delivers an additional 0.7% fuel burn improvement. CF6-80E engines also feature longer LLP* life than its competing engine – resulting in lower maintenance cost, which can mean up to a $2 million savings per aircraft across the lifecycle**.

The legacy continues

The future remains bright for the CF6, as current production volume remains at a consistent level over the next few years. Engines that are being built today for the Boeing 767 and the Airbus A330 will still be flying into the 2040-2050 timeframe – 80 years after the first flight in 1971.

In May 2016, Airfinance Journal survey results*** indicated the CF6 is a top-rated engine for Boeing 767 and 747 aircraft applications. CF6 is also a popular choice for existing freighters, as well as passenger-to-freight aircraft conversions. Ultimately, more than half of the CF6 engines in service are powering the Boeing and Airbus freighters of today.
