Lycoming-IO390 - Lycoming IO-390
Lycoming-IO390

The Lycoming IO-390 engine is a horizontally opposed, four-cylinder aircraft engine, manufactured by Lycoming Engines.[1][2]

There is no carburetted version of the engine, which would have been designated O-390 and therefore the base model is the IO-390.[1][2]

Design and development

The engine was originally conceived in the 1970s as the IO-400-X, but the project was never pursued.[3]

The IO-390 family of engines, which Lycoming refers to as the IO-390-X, produce 200 hp (149 kW) to 210 hp (157 kW). The IO-390 was developed from the similar IO-360 engine, by using cylinders from the IO-580 to increase the O-360's cylinder bore. It features a tuned induction system, roller tappets and Slick Start ignition. The engine has a fuel injection system which meters fuel in proportion to the induction airflow with fuel vaporization taking place at the intake ports. The engine has a displacement of 390 cubic inches (6.39 litres). The cylinders have air-cooled heads.[1][2][3]

The IO-390 was first introduced at AirVenture 2002. It has a factory recommended TBO of 2000 hours and requires a dynafocal engine mount.[2][3]

The IO-390 was initially marketed through Lycoming's custom engine subsidiary, Thunderbolt Engines, prior to the engine's certification and was at that time only available for installation on non-certified aircraft. The IO-390 was certified on 30 March 2009 to FAR 33 effective February 1, 1965, as amended by 33-1 through 33-24.[1][2][3][4]

In January 2009 the base price of the IO-390-EXP version was USD$32,650.00.[5]

In November 2009 Lycoming announced that it had obtained an FAA Supplemental Type Certificate to replace the originally fitted Lycoming O-360 engines in the Mooney M20E, M20F and M20J with a new or remanufactured IO-390-A3A6 engine.[6] Also on November 12, 2009 Commander Aircraft received an STC for its model 112B using the MTV-12-B/188-59b propeller.[7]
