Textron ( TXT) said Thursday that fourth-quarter earnings will exceed its guidance, as strong performances at several of its divisions offset higher-than-expected costs at one of its Bell Helicopter programs.

The CEO of the Bell division, meanwhile, resigned from the company.

Textron's previous guidance range called for fourth-quarter earnings from continuing operations of $1.35 to $1.45 a share. The industrial company said a good performance at Cessna, Textron Systems and Textron Financial, plus a lower tax rate, will help it beat those numbers. Analysts polled by Thomson Financial predict earnings of $1.46 a share.

Those gains came despite additional costs related to its Bell Helicopter H-1 program during the quarter, Textron said. In a press release separate from its fourth-quarter forecast, Textron said that Bell President and CEO Michael Redenbaugh resigned.

The company named Richard Millman, who had been president of Textron Systems, as Bell's new CEO.

"With the tremendous growth trajectory anticipated for Bell Helicopter, we are putting a strong operations executive in place to ensure we meet the current and future needs of our customers," said Textron Chairman, President and CEO Lewis B. Campbell in a statement. "There are wonderful growth opportunities ahead, and we are accelerating our focus on execution to ensure we make the most of them."

Frank Tempesta will replace Millman as president of Textron Systems. Tempesta most recently was vice president and chief operating officer of the division.

Shares of Textron were down $2.15, or 2.2%, to $95.75 in after-hours trading.
