A vast majority of CSeries supplier agreements have already been inked by Bombardier, which expects to reach preliminary design freeze on the aircraft later this year and final design freeze in late 2010.

Bombardier Commercial Aircraft programmes vice-president Ben Boehm reveals to ATI that while not all CSeries awards have been publicly announced, a total 96% of billable materials for the aircraft have been contracted out.

One deal that has not been announced is the award for the electric brakes for the CSeries. A Bombardier testbed aircraft equipped entirely with an all-electric braking system from Meggitt executed its first flight in October, however.

The remaining 4% constitutes "consumables and the flight deck seats", under which Bombardier is considering adding a J-shaped track for "easier ingress and egress", says Boehm.

Major suppliers for the CSeries include Shenyang Aircraft Corporation (SAC), a subsidiary of the state-owned aviation industrial entity China Aviation Industry Corporation (AVIC) that will supply the centre fuselage on the CSeries.

Bombardier's Belfast plant will develop and produce the CSeries' advanced composite wings. Alenia Aeronautica has been selected to provide the horizontal and vertical stabilisers, while Fokker Elmo will be responsible for the design and production of the entire wiring and interconnection system. Goodrich Actuation Systems will supply the design and production of the flap and slat actuation systems. And Rockwell Collins is supplying the avionics.

Other announced suppliers include interiors specialist C&D Zodiac; Parker Hannifin Corp for design and production of the fully integrated fuel and hydraulics systems; and Liebherr-Aerospace Toulouse SAS for the design and production of the aircraft's air management system.
