MAINTENANCE MANUAL EXTRA 300LT
72-10-00 ENGINE
The engine installed is a TEXTRON Lycoming 6-cylinder
direct drive, horizontally opposed, air cooled engine.
Engine type:
AEIO-580-B1A 315 HP @ 2700 RPM
Figure 1 shows the Lycoming engine of the EXTRA 300LT:
The induction system is equipped with a BENDIX RSA-10
fuel injection system which is attitude independent.
The fuel is injected into the intake ports of each cylinder. The
mixture control is proportional to the intake air flow. A
manual mixture adjustment as an overriding system is
provided. The power setting is done manually by means of a
butterfly valve in the air induction tube.
The engine is air cooled. Baffles are provided to build up
pressure and to force the air through the cylinder fins. The
cooling air flow is dependent on engine speed and dynamic
air pressure.
The engine is lubricated by means of an engine driven oil
pump. The system uses an oil sump as reservoir. For acro-
batic maneuvers, lubrication is assured via an inverted flight
oil system (refer to CHRISTEN 801 Inverted Oil Sytem and
chapter 79).
