Boeing (Chicago) has announced that it intends to build the new 737 MAX in Renton, Washington, pending approval of an early contract extension with the International Association of Machinists and Aerospace Workers (IAM), the union representing hourly employees in Washington, Oregon and Kansas.

As part of an effort to improve their relationship, Boeing and the IAM have been discussing the potential for an early contract extension for several weeks. The current contract is set to expire in September 2012 .

Independent of that effort, Boeing has been conducting a review of potential sites for 737 MAX production since the company announced in August that it will build a new-engine variant of the market-leading 737.

Boeing has assessed the business case for locating production of the 737 MAX in Renton in light of the economics of a proposed new labor agreement, and the company is prepared to locate 737 MAX production in Renton provided the economics contained in that proposal are achieved.

To date, Boeing has received more than 700 commitments from our customers for the 737 MAX. The new airplane is expected to enter service in 2017.

Although not mentioned in the press release, the proposed deal probably includes the IAM dropping their objection to the second 787 production line in Charleston, SC.
