Bombardier CSeries Flight Test Vehicle four (FTV4) resumed flight tests from Bombardier’s facility in Mirabel, Québec on September 15, 2014. The flight comes a week after FTV2 resumed flight testing activities on September 7, following grounding in May 29, 2014, after FTV1 experienced a uncontained engine failure due to faulty oil lubrication system.
