Boeing moved quickly this month to erase any doubts about the progress of the 787 flight-test program after “an assessment of the availability of an engine needed for the final phases of flight test this fall” led it to conclude that it couldn’t deliver the first production airplane until the middle of next year’s first quarter. Last week, all five flight-test airplanes remained active, said Boeing.

Pratt & Whitney and CFM might not like to hear it, but if the assertions of Boeing CFO James Bell prove accurate, the 15- to 16-percent fuel efficiency gains the engine makers have repeatedly advertised for their respective next-generation turbofans will translate into less than double digits if and when they make their way onto existing narrowbodies.
The third Sukhoi Superjet 100 landed in Italy for the first time yesterday at Turin Caselle Airport, where it continued its flight test campaign in preparation for expected year-end certification. The aircraft (prototype S/N 950004) took off from the Sukhoi Civil Aircraft’s flight test center in Zhukovsky, near Moscow.
Rolls-Royce today filed a complaint alleging infringement by United Technologies Corp. (UTC) of the Rolls-Royce swept fan blade patent. The complaint specifically identifies the fan stages on both the Engine Alliance GP7200 engine and the Pratt & Whitney PW1000G engine. It also alleges that a number of other UTC aerospace civil engines infringe the Rolls-Royce patent.
Pratt & Whitney has completed assembly of its first PurePower PW1524G engine for the Bombardier C Series. The company held a so-called "last bolt" ceremony today at its Middletown Engine Center in Connecticut to commemorate the milestone. Pratt plans to deliver the engine to its West Palm Beach, Fla. facility later this month to start testing.
International Aero Engines (IAE) has identified a problem area with some of its V2500 engines and is inspecting engines in the fleet as a result. The issue involved the engine's high-pressure compressor (HPC), specifically the third through eighth stages of the 10-stage HPC requiring certain fasteners' replacement. This issue has resulted in the grounding of nine of Kingfisher Airlines' 34 Airbus A320s.
The U.S. FAA and Europe’s EASA jointly certified CFM International’s new CFM56-7BE engine for the Boeing 737 family last Friday.
CFM expects the engine to begin Boeing 737 flight testing during the fourth quarter and enter service in mid-2011, in time to coincide with Boeing Next-Generation 737 airframe improvements.
Should Airbus and Boeing put upgraded engines on their single-aisle airliners while waiting for the crop of next-gen turbofans with their promise of much better fuel, emissions and noise numbers?
The Engine Alliance GP7200 engine is in the middle of a weight-reduction program that may further help sales as the General Electric-Pratt & Whitney joint venture is engaged in at least three campaigns: with Qatar Airways, Kingfisher Airlines and Vietnam Airlines. The engine maker (Hall 4 Stand A10) expects 19 Airbus A380s to be in service flying its turbofans by the end of the year.
Rolls-Royce is putting all its cards on a new engine to power future single-aisle aircraft and told AIN that as far as it is concerned, “the numbers do not stack up” for re-engining either the Airbus A320 or Boeing 737.
