EVENDALE, Ohio (AP) _ One of the two largest unions at General Electric Co.'s jet engine plant in this Cincinnati suburb has voted to approve a new contract. Members of the largest union will vote Wednesday and Thursday.

The International Association of Machinists and Aerospace Workers unit in Evendale voted in favor of the three-year deal on Sunday, GE Aircraft Engines spokesman Rick Kennedy said. The 640-member union represents maintenance workers at the plant.

Joseph Sweeney, president of Lodge 912 of the International Association of Machinists, did not return telephone messages for comment Tuesday.

Charlie Highlander, president of United Auto Workers Local 647, which represents about 1,200 GE Aircraft production workers in Evendale and about 40 at a GE parts warehouse in Erlanger, Ky., said his union reached a tentative agreement with GE Sunday night. He declined to provide details.

Highlander said Local 647 members in Erlanger will vote Wednesday on the agreement and Evendale members are to vote Thursday.

The Evendale agreement with the machinists is similar to a national agreement ratified last week by the International Union of Electronic Workers and the United Electrical Workers of America, Kennedy said.

That three-year agreement included wage increases that will push the typical GE hourly worker's weekly paycheck to $910 by the end of the contract, and pension benefit increases of 15 percent over three years for GE workers who retire during the contract.
