Jet Air Group is an aviation business headquartered at Green Bay Austin Straubel International Airport (KGRB). We offer a full-service Signature Select fixed-base operator (FBO), aircraft maintenance, avionics, air charter services, flight training, and calibration at our Green Bay headquarters. A satellite location at the Sheboygan County Memorial Airport (SBM) offers flight training and aircraft rental.

Our primary customers are the owners, operators, pilots, and passengers of private general aviation aircraft. These aircraft range from small single-engine airplanes and helicopters all the way up to large jets. We also serve the fueling needs of the airlines at Green Bay Austin Straubel Airport, as well as government and military aircraft. Jet Air Group is not an airline, but our air charter department offers on-demand private air travel to the public.

Jet Air Group has been a leader in the aviation field in Wisconsin for more than 40 years and continues to grow.

Company History


Jet Air was established in 1969 in Clintonville, Wisconsin and in 1970 became an authorized Mitsubishi MU-2 Service Center. In the 70’s Jet Air also was a Service Center for the Fairchild SA226 and SA227 aircraft.


In 1980, Jet Air relocated to Green Bay, Wisconsin to support the new Mitsubishi MU-300, now known as the Beechjet 400, with a new maintenance facility.

Along with the Honeywell engines, Jet Air also became affiliated with Dallas Airmotive and Standard Aero, supporting the Pratt & Whitney PT6 and JT15 engines for the Beechcraft King Air, Piper Cheyenne, MU-300, Beechjet, and Cessna Citation.

We implemented our accessory shop, which included starter generator overhauls along with cleaning and flowing of the TPE331 and PT6 engine fuel nozzles.
