Sept. 6, 2016, © Leeham Co.: It was a stunning admission, one that produced the biggest headlines at the United Technologies media days in June: 44% of the suppliers on Pratt & Whitney’s Geared Turbo Fan engine weren’t performing to the UTC/PW standards.
The impact of this was seen today when Bombardier announced it will deliver only half the anticipated 15 C Series this year because of engine delivery issues by PW for the GTF powering the new airplane.
Bombardier and PW pointed the finger at its supply chain for the delays in delivering engines.
Airbus continues to have slow deliveries from PW after a bowing of the engine shaft was revealed under certain conditions. The A320neo is powered by a different version of the GTF than the C Series. It’s also powered by the CFM LEAP engine, which only recently went into service. There are no known issues with the LEAP.
PW said at the media days the bowing problem has been fixed, along with some software glitches. But during the factory tour, only two engines on display were identified by PW as the first production engines to have the fix.
Given the number of airplanes beginning to line the Airbus production line, reporters on the tour were surprised there weren’t more engines apparent and ready for shipment.
Airbus still has a reported completed 20 A320neos awaiting the GTF engine.
Neither Embraer nor Mitsubishi are affected at this time. EIS for their GTF-powered EJet-E2 and MRJ90 aren’t until 2018.
Airbus, Bombardier and affected customers are reported to be seeking compensation.
