OIL SYSTEM
The oil is cooled by a Two Cooler System mounted on the left hand side in the engine
compartment.
Alternatively a Single Cooler System is available. In this case the oil is cooled by one oil
cooler mounted on the aft, right hand side of the engine.
The oil level is determined by a dip-stick.
A thermostatic valve is fitted upstream of the oil cooler. This valve ensures a quick warm-up
of the oil after engine start.
Oil capacity and grades:
Max sump capacity
16 qts.
Min sump capacity
9 qts.
For temperatures and oil grades refer to Section 1.7.

ENGINE INSTALLATION
The engine is supported by four shock mounts (type LORD or BARRY CONTROLS), to the
tig-welded steel tube engine mount which is attached to the fuselage with four bolts on the
firewall axis.
The engine cowling is divided into two parts, a lower and an upper part both made of glass-
fibre/carbonfibre reinforced epoxy. The parts are fixed by a number of screws and the upper
cowling has a separate hatch for easy access to the oil dip-stick.
