The engine installed is a Rotax 912 iS Series injected engine providing 73.5
kW takeo power. All limits as defined by the engine manufacturer apply.
The engine can be operated with MOGAS or AVGAS 100LL, with max. 10%
ethanol and the following antiknock properties: min. RON 95 (min. AKI 91) as
by Rotax specification. The propeller is driven by a gearbox. The gearbox is

7.6.2 ENGINE COMPONENTS
Oil System
The dry-sump lubrication system contains 3.5 liters of oil and consists of an
oil tank, two coolers, a mechanically-driven pump and a thermostat. Once
the oil temperature reaches 80
o
C the thermostat opens, allowing the oil to
flow through the coolers. A dipstick is present on the oil tank to check oil
quantity.
CAUTION: The engine should not be operated with less than minimum in-
dicated quantity of oil (dipstick). For extended flights, oil quantity of at least
half-level between min and max deliminators is recommended.
Engine Cooling
The engine is air and water cooled. Cooling air enters the engine bay through
an inlet on the starboard side of the spinner and is then distributed over the
engine’s cylinders. The water cooling system consists of a cooler and me-
chanically-driven pump to provide cooling to cylinder heads. The heated air
exits the engine compartment through a common outlet on the bottom aft
portion of the cowling.
Fuel Pumps and Fuel Injection
The engine is fuel-injected. The fuel pressure is provided by two electric
pumps connected in series, equipped with bypass valves. Engine will op-
erate with either one or both pumps running (one is main, the second is
auxiliary). There are two fuel injectors per cylinder (8 in total). During engine
