Fairfield County Airport is a public use airport in Fairfield County, Ohio, United States. It is located three nautical miles (6 km) northwest of the central business district of Lancaster, the county seat. The airport is owned by the Fairfield County Commissioners.
Although most U.S. airports use the same three-letter location identifier for the FAA and IATA, this airport is assigned LHQ by the FAA but has no designation from the IATA.
The airport regularly hosts community events such as fly-ins. These events feature food trucks, historic aircraft displays, vintage cars, museum tours, law enforcement displays, and more.
Some of these events are hosted by the Experimental Aircraft Association, which has a chapter at the airport. The Young Eagles regularly host free flights at the airport. The Historical Aircraft Squadron is also located at the airport.
The airport, previously known as Port Lancaster, was purchased by Anchor Hocking Corporation. In 1959, the company began operating a Beechcraft E18 factory equipped with rocket-equipped takeoff, replacing one of two previous Beechcraft planes operated by the company. The airport and its runway were donated to the county in mid July 1968. The airport was dedicated on 18 June 1969. It was again dedicated on 29 August 1971. At the time it had a runway and a terminal building was nearly complete.
A skydiving company was blocked from moving to the airport in 2008 over concerns that skydivers would conflict with planes taking off and landing at the airport.
In 2010, residents nearby objected to moving a road near the airport closer to houses. The road would be relocated to address safety concerns raised by the FAA, who argued pilots needed to fly too close to the road and descent too steeply after it to make a safe landing. Moving the road would allow the entirety of the runway to be used for landing instead of forcing the threshold to be displaced. The road was moved by circa 2019.
Fairfield County Airport covers an area of at an elevation of 868 feet (265 m) above mean sea level. It has one runway designated 10/28 with an asphalt surface measuring 5,003 by 75 feet (1,525 x 23 m).
Currently there is one Standard Terminal Arrival (GUNNE ONE) and four instrument approaches (an RNAV GPS approach in to runway 10 and 28, a localizer for 28 and a VOR or GPS-A circling approach) to the airport.
Sundowner Aviation was the Fixed-Base Operator, which provides fuel, maintenance, flight instruction, charter flights, hangars and tie-downs, Lasergrade testing, WSI aviation weather, and car rental.
In 2023, plans were announced to build 14 new hangars at the airport at a cost of $5 million.
For the 12-month period ending July 29, 2021, the airport had 43,582 aircraft operations, an average of 119 per day: nearly 100% general aviation and <1% military. At that time there were 106 aircraft based at this airport: 87 single-engine and 9 multi-engine airplanes, 8 helicopters, 1 jet, and 1 ultralight.
