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]
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 3 ⁄16 inch (4.76 mm), developing 210 hp (157 kW).
