Bombardier Aerospace rolled out the first CSeries flight test vehicle (FTV1) Thursday at its Montreal Mirabel facility and announced an extended variant of the CS300 that can carry up to 160 passengers.

FTV1 will make its first flight by end of June and is on schedule for entry into service one year later, by mid-2014, Bombardier executives said.

AirBaltic and two other undisclosed airlines have signed up for the CS300 extra capacity variant. AirBaltic’s version will have 148 seats. At 160 seats, with a seat pitch of 28 in., the CS300 will have the same seat costs as a 180-seat narrowbody, CSeries VP and general manager Robert Dewar said.

The extra capacity variant will be achieved by a mid-fuselage extension, a second pair of overwing exits and will be retrofittable, Dewar said.

Bombardier Commercial Aircraft president Mike Arcamone said the first CS300 aircraft will begin its flight test schedule in early 2014 with an entry into service date planned for the end of 2014.

Arcamone said Bombardier has orders and commitments for 382 aircraft from 14 customers. The manufacturer is not breaking out the split between CS100s and CS300s, but Dewar said the CS300 was tracking “slightly larger orders.”

Lufthansa Group is the launch customer for the CSeries for Swiss, but the first entry-into-service airline has not been revealed.
