MONTREAL - Bombardier Inc. says that its new CSeries jetliners will need additional testing and the first planes won't go into service until next year -- several months later than previously expected.
The Montreal-based company now says it expects the CS100 will go into service in the second half of 2015.
It says the larger CS300 model will go into service about six months after that.
The initial CSeries planes were expected to be ready for service late this year or early in 2015 after 12 months of flight tests, which began in mid-September last year.
Bombardier says the plane's initial performance has been in line with its expectations but the company has decided to take more time to ensure it has what it calls "overall system maturity."
