GE Aviation has secured a $900m contract from Etihad Airways to deliver its GEnx-1B engines to power ten Boeing 787 Dreamliners and two Boeing 777 freighters.

The contract includes a 15-year OnPoint solution agreement with GE Aviation for the maintenance, repair and overhaul of the ordered GEnx engines.

GE Aviation president and CEO David Joyce said: "GE Aviation is pleased with Etihad’s selection of GE90-powered Boeing 777 Freighters and the GEnx engine for its additional ten Boeing 787 Dreamliner aircraft.

"The GEnx-1B engine selection reaffirms the carrier’s dedication to the engine and we look forward to delivering this advanced technology engine along with the proven GE90 engines to Etihad."

Etihad Airways previously signed a $2.8bn contract with Boeing to buy ten 787-9 Dreamliners and a pair of 777 Freighters on 12 December 2011.

The 787 Dreamliners, powered by GEnx, will seat 290 passengers and offer a range of up to 8,500nm.

The GEnx-powered Dreamliner is scheduled to enter service by 2012.

The contract follows Etihad Airways’ $2.2bn order for GEnx-1B engines to power its fleet of 35 Boeing 787-9 aircraft and GE90-115Bs to power ten Boeing 777-300ER aircraft.

Etihad Airways CEO James Hogan said: "We are delighted to expand our successful partnership with GE by purchasing the GEnx and GE90 engines to support our recently announced order for an additional 12 Boeing aircraft.

"Etihad Airways works with a number of suppliers seeking opportunities to reduce our noise and carbon emissions. The GE engines we have selected for our Boeing fleet reiterates our commitment to this objective."

Etihad Airways currently operates a fleet of 57 aircraft and close to 1,000 flights a week serving about 67 destinations in 45 countries, the company said.
