Wisconsin Based Business Aviation Fleet Totals 368 Turboprops and Jets, With 30 Listed for Sale or Lease

Wisconsin is home to 368 in-operation turboprops and business jets, according to an analysis of the current in-state fleet published by Holstein Aviation. The fleet is based at 46 airports, led by Southern Wisconsin Regional Airport and Waukesha County Airport.

The average manufacture year is 2007 and the median is 2008. About 33 percent of the fleet (121 aircraft) were built in 2015 or later, 81 aircraft (22 percent) date to 2020 or newer, and 38 aircraft (10 percent) were built before 1990. Airframes range from a 1971 model to 2026 deliveries.

Southern Wisconsin Regional holds about 11 percent of the state's business aircraft, and the top two airports together account for about 22 percent. Adding Kenosha and General Mitchell, those four southern and southeastern fields hold 140 aircraft, or 38 percent of the statewide fleet. The top ten airports hold roughly 68 percent.

Citation is the leading manufacturer with 104 aircraft, more than triple the next closest maker. Embraer (28), Gulfstream (25), SOCATA (25) and Challenger (24) complete the top five, with Hawker, King Air and Falcon close behind. The Caravan 208B is the most common single model, though the market is more jet-driven than turboprop-driven. In all, 136 distinct models appear in the fleet.

Thirty of the 368 aircraft, about 8 percent, are listed for sale or lease. Eighteen carry a published asking price and 12 are listed as "inquire." Citations account for nine listings, followed by three Hawkers and three Learjets.

Published asking prices range from $595k for a 1971 King Air 100 to $7,499k for a 2026 Citation M2 Gen2. Southern Wisconsin Regional has the most listings (10), followed by Kenosha Regional (5) and Waukesha County (3).

About 254 distinct operators appear across the fleet. By usage, 279 aircraft (76 percent) fly business missions and 55 (15 percent) are in charter service; the rest fly personal, dealer-inventory, cargo, government and other roles.

In all, 98 aircraft (27 percent) are maintained under FAR Part 135. Airframes with recorded flight-hour data average about 4,460 total hours, with a median of 3,800.

A state fleet like this shows how regional business aviation tends to concentrate. Four southern and southeastern airports hold 38 percent of the aircraft and ten airports hold roughly 68 percent, so ramp, hangar and maintenance demand clusters around a handful of fields rather than spreading evenly across the 46 airports in the count.

Manufacturer concentration works the same way. With Citation at 104 aircraft and the next maker at 28, parts, training and service capacity for one product family carries outsized weight in the local support market. A median manufacture year of 2008 alongside 121 aircraft built in 2015 or later points to a fleet that is still being renewed rather than aging in place.

The resale picture is narrow: 30 listings out of 368 aircraft is about 8 percent, and 12 of them carry no published price. Asking prices from $595k to $7,499k span very different aircraft, so the listed set says little about where values are moving. The listings on the market, and how many move from "inquire" to a published price, are the clearest next signal.
