SEATTLE -

An Associated Press analysis finds that some machinists in the Puget Sound region would likely see their annual base salaries top $100,000 in the coming years under a proposed contract offer from Boeing.

A group of top-level union workers at Boeing already earn more than $90,000 in base pay annually, not counting shift differentials, overtime or incentive payments.

While the contract offer going to a vote Friday would slow the growth of machinists' wages starting in 2016, workers would still get regular cost-of-living adjustments, plus an extra 1 percent pay increase every other year.

Boeing says approval of the contract this week would ensure that the 777X will be built in the Puget Sound area, including the fuselage, wing fabrication and final assembly.
