Bombardier resumes CSeries test flights

Bombardier has confirmed test flights for its CSeries aircraft have resumed, after engine issues grounded the plane in late May.

According to a release from the company, the Sunday test flight at Mirabel followed an in-depth review and analysis of an ‘engine-related incident,’ which occurred during stationary ground maintenance testing on May 29. Both Bombardier and engine manufacturer Pratt and Whitney have addressed the issue, including the modification of the engine’s oil lubrication system, the company says.

Rob Dewar, Vice President, CSeries Aircraft Program, said that the engine has “more than 10,000 hours of ground and flight testing and we’re confident that it will enter into service meeting or exceeding the fuel burn, emissions, thrust and noise specifications, as promised by Pratt & Whitney.”

Bombardier says the CSeries aircraft’s entry-into-service remains on track for the second half of 2015.
