TORONTO: Canada’s Bombardier said the engine failure on its CSeries test plane last week occurred in the low-pressure turbine and that the airframe on the jet had been damaged.
Spokesman Marc Duchesne confirmed the details reported in a UBS research note that cited meetings with chief executive Pierre Beaudoin and senior investor relations director Shirley Chenier.
The engine has been disassembled, Pratt & Whitney said on Friday, adding that after an in-depth review, “we understand the issue and have developed a plan with Bombardier to resume ground and flight testing.”
Bombardier downplayed the impact of the engine failure to the test schedule of the $4.4 billion jetliner programme. Its shares, which fell after the incident last week, rose more than 2.4 per cent on Friday to C$3.82.
Throughout the week, there had been cautious optimism within the industry and among analysts that the fallout from the incident would be limited.
“Preliminary findings indicate that the engine failure is not related to the engine’s gearbox. The engine that experienced the failure last week had had problems in the weeks prior to the incident and it had been repaired here in Mirabel,” Duchesne said.
“It seemed OK and ready to fly and it did, and then there was the incident.”
The failure took place during stationary maintenance testing of the CSeries, which Montreal-based Bombardier is hoping will compete with smaller narrow-body jets made by Boeing Co BA.N and Airbus.
“Bombardier ... suggested that a manufacturing defect, rather than a design flaw, may have been the cause.”
