Bombardier closed 2017 without achieving its revised and steeply-reduced CSeries delivery target for the year, having handed over 17 CS100s and CS300s in 2017.
The aircraft include three CS100s and seven CS300s handed over to Swiss, five CS300s delivered to Air Baltic and two CS300s delivered to Korean Air, according to the company and Flight Fleets Analyzer.
Bombardier kicked off 2017 aiming to deliver 30 to 35 CSeries in the year, but production delays stemming from issues with engine maker Pratt & Whitney led it to trim the forecast on 2 November to 20-22 aircraft.
Then on 18 December Bombardier executives, speaking during a trade hearing, said the goal was 20 aircraft.
Despite missing the delivery target, Bombardier closed 2017 having secured a third operating customer – Korean Air – and having expanded the aircraft's presence into Asia.
Bombardier handed over the first CS300 to Korean on 22 December 2017, and a second CS300 left the manufacturing site in Mirabel near Montreal on 30 December, bound for Korean.
Korean has said it intends to place CS300s in service on domestic routes starting 16 January.
The carrier, which has orders for 10 CS300s and options for another ten aircraft, placed the order in July 2011 and had expected to receive seven CS300s in 2017, according to a fleet plan it released in early 2017.
Bombardier did immediately comment about why it did not reach the 20-aircraft goal.
