Bombardier Commercial Aircraft confirmed that the CSeries aircraft resumed flight testing with flight test vehicle two (FTV2) taking flight today at Bombardier’s facility in Mirabel, Québec.

The flight today follows an in-depth review and analysis of the engine-related incident that occurred during stationary ground maintenance testing involving CSeries aircraft FTV1 on May 29 at the Mirabel facility. Pratt and Whitney alongside Bombardier, has taken appropriate measures to address the issue, including the modification of the engine’s oil lubrication system.

“We are pleased to see the CSeries aircraft back in the air. The geared turbofan (GTF) engine has over 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,” said Rob Dewar, Vice President, CSeries Aircraft Program, Bombardier Commercial Aircraft.

“Aircraft flight test programs are complex and involve extreme testing meant to draw out any potential issues and correct them prior to entry-into-service,” added Mr. Dewar.

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