3.3.3.2.3 SAFETY CHECK
OFF – Ignition and Master
3.3.3.3 CARBURETOR ICING
A gradual loss of RPM and eventual engine roughness may result from
the formation of carburetor ice. The chance of the formation of carburetor
ice is reduced by the use of a carburetor heater warmed by engine
coolant and is always on the Adventure Configuration (912ULS powered).
On Elite configuration with 914UL powered aircraft, the chance of
carburetor icing is reduced by the use of the turbo compressor and the
engine cowling where some hot air is directed to the air filters under the
cowling continuously. Thus no pilot action to turn on carburetor heat is
required.
3.3.3.4 SPARK PLUG FOULING
A slight engine roughness in flight may be caused by one or more spark
plugs becoming fouled. This may be verified by turning the ignition switch
from BOTH to either L or R position. An obvious power loss in a single
ignition operation is evidence of spark plug trouble.
