Bombardier Resumes CSeries Flight Tests: Canadian Company Had Halted Test Flights After an Engine Failure in May

Bombardier Inc. said on Sunday it resumed test flights of its CSeries jet, after being grounded for more than three months following a major engine failure.

One of the 110-seat CSeries jet test aircraft departed the company's Mirabel, Québec, facility late Sunday afternoon, kicking off a return to its flight-test campaign that the Canadian transportation company aims to complete by the second half of 2015.

One of its four active test aircraft on May 29 suffered a major failure of its Pratt & Whitney geared turbofan engines, putting a halt to test flying while the engine maker devised a modification to the oil system, which was identified as the failure's root cause.

Bombardier on Sept. 5 announced test flying would resume by the end of September after the company's second test aircraft was rolled out that same day with updated Pratt engines. Pratt & Whitney is a unit of United Technologies Corp.

The CSeries competes with the smallest single-aisle jets from Boeing Co. and Airbus Group NV.
