Rochelle Municipal Airport, also known as Koritz Field, is a city-owned public-use airport located two nautical miles (2.3 mi, 3.7 km) south of the central business district of Rochelle, a city in Ogle County, Illinois, United States. It is included in the FAA's National Plan of Integrated Airport Systems for 2011–2015, which categorized it as a general aviation facility.

Accidents & incidents

 * On August 21, 2017, a tailwheel-equipped Cessna 170 crashed while landing at the Rochelle Airport. The pilot reported that, during the landing touchdown, the wind shifted to a tailwind. The pilot attempted to go around but was unable to. Subsequently, the airplane drifted to the left of the runway, the right main landing gear collapsed, and the right wing impacted the ground. The probable cause of the accident was found to be the pilot’s failure to maintain directional control during landing with a tailwind.
