5 Emergency Procedures
5.1 Power loss and abnormal engine behaviour
● Power lever “FULL FORWARD”
● Select the fuel tank with sufficient fuel level.
● Continue engine operation
● If abnormal engine behavior is still evident land as soon as possible
In case of electrical failures in power generation the internal EECU voter switches automatically to the
ECU which provides the better engine performance.
In case of doubt the automatic decision can be overruled manually by switching to the
ECU A or ECU B voter position. If the manual override does not provide a better performance it is
strongly recommended to switch back to the automatic voter position.
Depending on the failure it is possible that the EECU uses default values for further operation. Refer to
chapter 6.6.3 for detailed error handling information.
5.2 Low Oil Pressure
● Power lever “FULL FORWARD”
● if the oil pressure rises into green continue operation in the green range
● if the oil pressure remains low Power Lever “IDLE”
● Land as soon as possible
● expect sudden engine stoppage
5.3 High Oil Temperature
● Reduce power
● Monitor oil temperature
● Land as soon as possible
5.4 High Gearbox Oil Temperature
● Reduce power
● Monitor oil temperature
● Increase gearbox cooling by e.g. increase airspeed
