Boeing has obtained US FAA certification of the 787 with Rolls-Royce Trent 1000 Package B engines, capping a seven month flight test programme for the enhanced 70,000lb thrust turbofan.
Package B upgrades include a modified low-pressure turbine design, relocation of the intermediate pressure compressor bleed off-take ports and improved aerodynamics for the fan outlet guide vanes.
Launch customer All Nippon Airways, will be the first to receive the engines, which Flightglobal has reported will bring specific fuel consumption to within 1% of the original specification.
European Aviation Safety Agency regulators approved the Package B version of the engine earlier this month.
