Motor STOP
If possible the engine should not be stopped when it is very hot. As the cooling liquid and the fuel are
not pumped anymore it may create vapour lock problems due the residual heat.
Generally it is enough if the landing is made with reduced power setting and following taxiing to cool
down the motor temperature sufficiently to enable an immediate stopping of the motor.
• Throttle set to idle
• Switch OFF all electrical consumers.
If a NESIS is installed it should be switched OFF only after the motor has been stopped, in order to
secure the safeguarding of the log book and the last flight.
• Switch OFF the fuel pump
If the engine is still running for a few seconds, it reduces the remaining pressure in the fuel
system.
• Switch OFF both ignition circuits, then the engine stops
• Switch OFF the ECU
• Turn OFF the start release key switch
• For parking maintain this status and if required remove the key
ENGINE Checking
If the last flight has been without any conspicuous behaviour, then the pre-flight check is limited to
following:
• Control of cooling liquid Sight control of the overflow reservoir
Open maintenance trap
• Control of the oil level Sight control of the oil reservoir
Open maintenance trap
WARNING
As usual with all engines having dry sump lubrication, the highest level is reached only after the
propeller has been turned a few times by hand until the typical gurgling noise is heard from the oil
reservoir. This reservoir installed in your aircraft is normally equipped with a sight tube showing the
oil level and therefore the control of the level is made visually.
MAKE SURE THAT ALL POWER SWITCHES ARE IN ‘OFF’ POSITION !!!
