The Lycoming O-360 is a family of four-cylinder, direct-drive, horizontally opposed, air-cooled, piston aircraft engines. Engines in the O-360 series produce between 145 and 225 horsepower (109 to 168 kW), with the basic O-360 producing 180.[1]

The engine family has been installed in thousands of aircraft, including the Cessna 172, Piper Cherokee/Archer, Grumman Tiger, and many home-built craft. It has a factory rated time between overhaul (TBO) of 2000 hours[1] or twelve years.[2]

The first O-360 certified was the A1A model, certified on 20 July 1955 to United States CAR 13 effective March 5, 1952 as amended by 13-1 and 13-2.[3] The Lycoming IO-390 is an O-360 which has had its cylinder bore increased by 316 inch (4.76 mm), developing 210 hp (157 kW) .[4][5]
