Hawthorne Global Aviation Services has been busy over the last year.

In March, the company opened its newly built FBO at Chicago Executive Airport (KPWK), acquired the Atlantic Executive Jet Center at Atlanta’s Cobb County Airport (KRYY) in July, and two months later announced plans to offer U.S. Customs inspection there by 2015.

The new Chicago facility features 30,000 sq. ft. of Class A hangar space that can accommodate a range of business aircraft up to Gulfstream G650 size. It currently has four tenants. In addition, the new FBO has a 10,000-sq.-ft. terminal for passengers and amenities, including pilot lounges and conference facilities. It offers computer flight planning and weather service, deicing and after-hours fuel and emergency services. The Chicago acquisition broadens Hawthorns geographic footprint of FBOs in the U.S., particularly in the large Midwest market. Chicago Executive has three active runways on 412 acres and is a major reliever for O’Hare International.

The acquisition of the Atlanta sole-source FBO at KRYY, which has more than 500,000 sq. ft. of hangar space and a 6,000-sq.-ft. passenger terminal. Cobb County is the second busiest general aviation airport in Georgia, and is expected to grow. Groundbreaking for the U.S. Customs facility took place in mid-September.

Hawthorne this month acquired Heartland Aviation at Chippewa Valley Regional Airport (KEAU) in Eau Claire, Wisconsin, bringing to five the number of FBOs in Hawthorne’s nationwide network.

Hawthorne president and CEO Steven Levesque outlined what kind of growth vehicle would fit into Hawthorne’s long-term plans. “We look at a growing market that has an FBO with a long-term lease,” he told ShowNews. “We like to see one million gallons of retail fuel, and facilities that are in good shape. They don’t have to be new, but good enough to provide the level of service we offer.”

In other developments, Hawthorne is still developing the Boeing BBJ hangar at its FBO at MacArthur Airport (KISP) in Islip, N.Y. The hangar is currently going through “planning and permitting,” said Levesque. “We have had a few changes in the plans, but are moving forward and will seek approval from the town of Islip.” In March Hawthorne expanded its maintenance operations at KISP by adding a second maintenance work shift to satisfy demand. Excelaire Services, Inc., Hawthorne’s air charter company, recently added an 18-seat Gulfstream GIV to its fleet, bringing aircraft strength up to 21. The company is at capacity at Islip, which is why the BBJ hangar is badly needed, said Levesque.

Hawthorne’s FBO at Lakefront Airport near New Orleans, which it acquired in 2012, took over a new hangar in June to meet demand. Hawthorne is at Booth 3031 here.
