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 horsepower. [1]

Contents

The engine family has been installed in thousands of aircraft, including the Cessna 172, Piper Cherokee/Archer, Grumman Tiger, and many home-built types. It has a factory rated time between overhaul (TBO) of 2000 hours [1] or twelve years. [2] O-360 family engines are also widely used in airboats, most notably in the Hurricane Aircats used by the US Army during the Vietnam War. [3]

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. [4] 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). [5] [6]

Series

The O-360 family of engines comprises 167 different models with 12 different prefixes. All have a 361-cubic-inch (5.92-liter) displacement and 5.125 and 4.375 in (130.2 and 111.1 mm) bore and stroke. [4] [7] [8] [9]
