This chapter gives information on the engine and its assemblies that are installed in the
aircraft. For operation and maintenance on the engine, refer to the applicable Lycoming
Manual as in chapter 01-0-00.
72-10-00 ENGINE
The engine installed in the aircraft is a Textron Lycoming type AEIO-580-B1A 6-cylinder,
direct drive, horizontally-opposed, air-cooled aerobatic aircraft engine.
The engine is a normally aspirated engine and supplies 315HP at 2.700 RPM.
The engine is attached to the engine mount with four mounting points and shock mounts.
For further information on the mounting, refer to chapter 71.
The induction system has a Bendix RSA-10AD1 fuel injector.
Fuel is injected into the intake ports of each cylinder.
You can adjust the power setting manually with a butterfly valve in the air intake.
The mixture is controlled in relation to the intake air flow.
The engine is air-cooled. The air can get access to the engine compartment through the two
inlets on the front of the cowling. The baffling is an aid to get the correct airflow through the
cylinder fins. The baffling has rubber edges to accurately attach to the shape of the adjacent
cowling.
An engine-driven oil pump lubricates the engine. For aerobatic maneuvers, an inverted oil
system is installed.
Two oil coolers (Setrab P/N 50-113-7612) control the oil temperature. For more information
on the oil system, refer to chapter 79.
The ignition system has two magnetos that operate independently: Slick 6393 on the left
side and Slick 6350 on the right side.
If you replaced the engine control cables, apply RTV 106 sealant to the bushing grooves and
gaps at the engine side of the fire wall.
To remove the engine:
1.
Remove the cowlings, refer to chapter 71-10-00.
2.
Make the aircraft level, refer to chapter 08-10-00.
3.
Drain the engine oil.
4.

To remove the engine from the engine mount, you must disconnect the ignition
harnesses of cylinders 2-4-6.
