Topeka ? Gov. Mark Parkinson on Friday said he thought the Kansas economy was on the upswing.

“I do think we are recovering,” Parkinson said.

If the state is recovering, it’s a slow recovery.

For the month of July, state tax collections were $424,000 below projections, despite a 1-cent increase in the state sales tax rate that went into effect at the start of the month.

Overall, tax revenue for July was nearly $380 million, which was slightly below earlier expectations, but 10 percent more than July 2009.

Parkinson said commercial aircraft manufacturing, a key part of the economy, was increasing, but the manufacture of smaller aircraft continued to struggle.

His comments were made before he went to Wichita to unveil details of an agreement between the state and Bombardier Learjet.

Under the deal, the state will provide $27 million in bond financing and Bombardier Learjet will secure Learjet 85 aircraft — a midsized jet — production and delivery in Wichita, which is a $600 million investment, the governor’s office said. The project will involve about 600 jobs.

“The agreement reached is a responsible investment that will not only keep the hard-working employees of Bombardier, but also create jobs and promote our state’s rich aviation industry,” Parkinson said.

Later in the day, the Kansas Department of Commerce announced that Hoefer Wysocki Architects will move its Country Club Plaza headquarters in Kansas City, Mo., to Lenexa.

The move will bring 65 jobs, $5.1 million in initial capital investment and up to 60 additional jobs over the next several years. HWA is eligible for more than $4 million in state incentives, including tax exemptions and work force training funds, the department said.
