Lebanon-Warren County Airport is a public airport located three miles (5 km) northwest of the central business district of Lebanon, on Greentree Road, in Warren County, Ohio, United States.
It is a county-owned public airport operated by the Warren County Airport Authority, a board of 9 members appointed by the County Commissioners. The runway, taxiway, and communication and navigation aids are County owned. The Airport Authority leases a terminal for public use on adjacent private property. The hangars, and other airport buildings are privately owned and operated. Daily airport management is handled under contract by fixed-base operator (FBO), Warren County Airport, Ltd.
The Southwest Ohio Regional Airport Authority was established in late 1961 to coordinate the efforts of 11 counties to build a new jet airport. Warren County joined the authority in January 1962 and began considering potential sites for the airport.
In late May 1965, John Lane proposed that the airstrip he and his wife operated, J. & J. Airport, be converted into the county airport. It was selected in early February 1966 and by the end of June 1967, a runway had been paved with blacktop and a new terminal building completed.
However, by 1977, the runway pavement was in poor condition and acres of woods at the end of the runway presented an obstruction.
By early October 1994, the airport was seeking a runway extension.
By late November 2008 the airport was found to still be in violation of FAA regulations regarding proximity of obstructions.
There is one North-South Runway (01/19). The runway is 4502' x 75' asphalt paved with lighting for night operation. The runway has displaced thresholds on both ends to clear obstructions. Airport elevation is 898'. There is a taxiway parallel to the runway.
Airport commissioners have been at odds with the Federal Aviation Administration over how best to upgrade the airport's facilities in recent years. In 2016, Warren County decided to foot the entire bill to repave taxiways at the airport instead of redo the airport's facilities in order to secure federal funding.
The airport has a fixed-base operator that offers many of the following services:
Three new hangars were built at the airport in 2012 at a cost of $1.7 million.
For the 12-month period ending August 4, 2021, the airport had 31,550 aircraft operations, an average of 86 per day: 98% general aviation, 2% air taxi and <1% military. There was at that time 101 aircraft based at this airport: 86 single-engine, 9 multi-engine, 2 jet, and 4 helicopter.
