Brodhead Airport carries FAA designator C37. Although privately owned, it is open to the public with no landing restrictions. Its three grass runways are shown on the Chicago sectional chart with an open circle. The airport is in uncontrolled (Class G) airspace, underlying Class E airspace. The nearest airspace requiring radio contact is Janesville (JVL) Class D, about 10 miles east. Madison (MSN) Class C airspace begins about 30 miles north.

The airport is about 1 mile south of Brodhead, near the junction of state highways 11 and 81. Monroe Airport (KEFT), about 11 NM west, is the nearest hard-surface airport and the nearest credit-card self serve fuel. The nearest instrument approach is also at Monroe, while Janesville has full ILS capability. Madison (MSN) and Rockford (RFD) provide radar service.

Brodhead Airport is fairly flat with a few trees. The perimeter is mostly surrounded by irrigated fields, so pilots should watch for irrigation rigs near the airport. There are no tall towers or other obstructions affecting the traffic pattern. All six runway thresholds are displaced for controlling objects.

Monitor and announce your intentions and be vigilant, as many aircraft using the field are not radio-equipped. Fly standard left-hand traffic patterns and look for aircraft possibly flying patterns to other runways. Please be predictable while flying near the airport. During fly-ins, pilots should check the surface markings because other runways may be closed.

EAA Cheeseland Chapter 431

The mission of Cheeseland Chapter #431 is to “Promote Aviation in the Brodhead Area,” and the group is active in educational outreach by hosting sport plane building seminars, Young Eagle airplane rides for students, sponsoring the Boy Scout Aviation merit badge, and providing EMS fire/rescue training for local first responders.

Chapter 431 also hosts three major “fly-in” events every year:

A Community Pancake Breakfast
A three-day Pietenpol/Hatz convention in July
A private three-day gathering of the Midwest Antique Airplane Club in September
For relief from cabin fever, the chapter also holds a Groundhog Chili Ski Fly-In on the first Saturday in February.

Chapter meetings are held on the first Tuesday of the month during the summer months and the first Saturday during the winter.

In 2013, Chapter 431 received tax-exempt status as a non-profit charity under IRS section 501(c)(3). Donations to Cheeseland Chapter 431, Inc. are tax-deductible.

Brodhead Airport has a rich history, beginning in 1946 when WWII pilot Bill Earleywine started a flight school and Taylorcraft dealership on a farmer’s field.

In 1973, a group of pilots and interested residents formed EAA Chapter 431 at Brodhead Airport. Two corporations were formed (Hawk Aire and Eagle Aire) to acquire the airport real estate along with additional acreage to make a runway extension to the west.
