Custer Airport, sometimes referred to as Monroe Custer Airport, is a city-owned public airport located in the city of Monroe in Monroe County, Michigan. The airport opened in November 1946 and was named for George Armstrong Custer, who spent much of his early life in Monroe. It is included in the Federal Aviation Administration (FAA) National Plan of Integrated Airport Systems for 2017–2021, in which it is categorized as a local general aviation facility.Custer Airport is owned by the city of Monroe and is financially supported through hangar rentals, landing fees, and fuel sales. It is located on North Custer Road (formerly designated as M-130) about two miles (3.2 km) northwest of Monroe's downtown area. The airport property itself—occupying 158acre—is an exclave of the city limits and is separated by a one-quarter mile (0.4 km) wide undeveloped residential area belonging to Frenchtown Charter Township. Since the city owns the airport, the area it occupies was incorporated into the city limits. Munson Park, the largest public recreation park in Monroe, occupies the land immediately east of the airport. The River Raisin is just south of the airport, and farmland surrounds the airport to the west and north.
