On the ground, check fuel or electrical system for possible cause. Replace filter(s), pump(s), lines,
pressure regulator or sensor as necessary.
Test the fuel system with ignition off and master switch and fuel pump on.
Single CHT and/or EGT drop
Verify that both CHT and EGT of the same cylinder have dropped. If not, CHT or EGT probe or signal
intake have a malfunction. Correct before next flight.

WARNING : A large deviation of both CHT and EGT temperatures in one cylinder, when
compared to the others, indicates that the particular cylinder is not firing properly
or is not firing at all. Engine delivers reduced power. Carry out
emergency/precautionary landing.
If it is not a sensor malfunction, send the engine to a ULPower authorised service-centre for
inspection/overhaul.
Knocking
Reduce engine power setting to the minimum necessary and keep engine temperatures well below
the maximum.

WARNING : Carry out emergency/precautionary landing.
Be sure the right fuel type and octane rating have been used.
Low battery voltage
Switch off all unnecessary electrical consumers, as engine needs battery to operate.

WARNING : Carry out emergency/precautionary landing.
To reduce electrical power consumption in flight even more, one ignition system can be turned off.
Keep in mind that ignition backup system is not operating at that time, but in the event of an
emergency, can be manually selected by switching second ignition system back on and switching
first off.
On the ground, have generator, battery and electrical systems checked for any malfunction. Verify
that no more than 15 Amps are being used by electrical devices other than the engine and fuel
pump.
