Spirit Aerosystems Inc. will design and build engine pylons and nacelle components for the Boeing Co.’s 747-8, the companies announced Wednesday.

The deal was hailed as Spirit Aerosystem’s first contract since Canadian firm Onex Corp. bought Boeing’s commercial aircraft operations in Kansas and Oklahoma in June and formed the Wichita-based subsidiary. Spirit builds parts for every Boeing commercial aircraft now in production, except the 717.

“This work package is not only a great addition to the work we currently perform for Boeing, but it also helps Spirit Aerosystems expand its product portfolio while providing new work for the future,” said Mike King, vice president of and general manager of propulsion structures.
