The second Bombardier CSeries CS100 flight-test vehicle returned to the air on September 7 after more than a three-month hiatus. FTV2 took off at 6:10 p.m.

Bombardier confirmed on Friday that the modified Pratt & Whitney PW1524G engines for the CSeries flight-test vehicles have successfully completed the testing required for return to flight test and that the second test vehicle (FTV2) will return to the air this month.
Two manufacturers shared the spoils of Japan Airlines’ major commitment announced last week covering a total of 47 regional jets. But the potentially bigger and undoubtedly more desperate winner proved to be Mitsubishi, the upstart regional jet manufacturer whose orderbook now shows memoranda of understanding, tentative agreements and firm orders from six customers.
Pratt & Whitney and Alcoa recently have revealed that the fan blades of the PW1000G family of geared turbofans will consist mainly of aluminum alloy–an industry first.
Pratt & Whitney on Sunday announced that is has managed to reduce fuel burn on the PW1100G-JM for the A320neo family by another 2 percent. Dubbed the PurePower Engine Advantage, the enhancement centers on improved aerodynamics and cooling.
Pratt & Whitney officials on Sunday afternoon identified the source of the failure of one of the PW1500Gs on the first Bombardier CSeries flight test aircraft as a “seal issue” in the oil system, not the low-pressure turbine, as was previously indicated by Bombardier. However, the officials refused to specify precisely where the oil leak originated or offer detailed information about the expected timing of its so-called fix.
While calling extending its geared turbofan engine family’s thrust rating by another 2,000 pounds “a big deal,” Pratt & Whitney next-generation product family vice president Bob Saia sees still bigger things in the company’s future, including what he called an Advanced GTF that could rival an open-rotor design in fuel efficiency by the middle of the next decade. For now, though, Saia finds himself “busy as a bee” with the five core programs already under way at the U.S. company.

Mitsubishi Aircraft took delivery early last month of its first Pratt & Whitney PurePower PW1200G geared turbofan at the Mitsubishi Regional Jet’s (MRJ) final-assembly factory in Aichi Prefecture, Japan. Delivery of the engine from Pratt & Whitney’s Mirabel Aerospace Center in Quebec marks a major milestone toward final assembly of the first MRJ90 flight-test aircraft, which Mitsubishi expects to fly during next year’s second quarter.
Airbus has finished assembling the first A320neo, the company announced Tuesday. The airplane, MSN6101, rolled out of its paint hangar in Toulouse, France, after receiving its Airbus house livery and installation of its Pratt & Whitney PW1100G-JM engines. The company started final assembly of the first A320neo in mid-March, with the attachment of the forward and aft fuselage sections, made in Airbus facilities in St. Nazaire, France and Hamburg, Germany, respectively.
