The second Bombardier CSeries CS100 flight-test vehicle returned to the air on September 7 after more than a three-month hiatus. FTV2 took off at 6:10 p.m. from Bombardier’s facilities in Mirabel, Quebec, for a 30-minute “return-to-service maintenance flight,” during which flight test pilots Muz Colquhoun and Chuck Ellis took the airplane to an altitude of roughly 10,000 feet and a top speed of 245 knots. The flight marked the successful resolution of an engine lubrication “issue” that resulted in an uncontained failure of the first flight-test vehicle’s left Pratt & Whitney PW1524G on May 29.
