Boeing said it will move production of the horizontal tail of its 787-9 Dreamliners from Seattle to Salt Lake City, Utah, and to Alenia of Italy by late 2012.
A company spokesman said the move would not result in any job losses in the Seattle plant.
"Once that work moves out of the development centre, other projects start coming through," Doug Alder said by phone.
With the move, Salt Lake City will have more than 100 jobs, he said.
Boeing expects the Salt Lake City facility to deliver their first stabiliser in the first quarter of 2013. The date for first delivery from Alenia is still being finalised, the company said.
