Wichita ? Cessna Aircraft Co. announced Wednesday it is cutting 665 jobs in Kansas and Oregon because of the global economic downturn.

Spokesman Doug Oliver said 500 layoffs will be made at Cessna’s 12,000-employee Wichita plant, which builds the company’s larger jets.

The other 165 cuts will occur at the Bend, Ore., plant, which has 460 employees producing a high-performance, single piston aircraft. Cessna and its parent company Textron Inc. acquired the plant from Columbia Aircraft Manufacturing Co. in December 2007 for $26.4 million.

No layoffs are planned at the Independence, Kan., plant that makes Cessna’s popular, entry-level Citation Mustang jet, Oliver said.

The large number of layoffs triggered a federal law requiring a 60-day notification period, meaning the cuts won’t take effect until late January or early February.
