3.3.3 In-flight Engine Failures
A)
ENGINE ROUGHNESS
1. Carburetor heat
PULL (ON)
2.
Fuel Pump
switch
ON
3. Ignition switch
SWITCH through the positions
L-BOTH, then R-BOTH
4. Throttle
Maintain setting
If roughness continues:
5. Throttle
REDUCE to min. required for flight
If roughness is acceptable:
6. Precautionary Landing
PERFORM (see 3.4.1)
If roughness is unacceptable:
gas bowden cable may be broken
6. Throttle
wide OPEN (increase engine power until
engine is running as calm as possible)
7. Propeller control lever
KEEP RPM in green range
When safe approach altitude for nearest landing field is reached:
8. Perform emergency landing with engine off according to section 3.4.2.
WARNING
If the gas bowden cable is broken, the spring-loaded throttle valve in the carburetor is opening
completely. With the failure only on one side, the engine will run very roughly and only by
setting full throttle on the still controllable carburetor safe climbing is still possible. For landing
the engine has to be turned off at a safe approach altitude.
B)
LOSS OF OIL PRESSURE
1. Oil Temperature
CHECK
If oil pressure sinks below the green range and the oil temperature remains normal:
2. Land at the nearest airfield
If oil pressure sinks below the green range and the oil temperature rises:
2. Throttle
REDUCE to min. required for flight
3. Precautionary landing
PERFORM, Engine may fail suddenly!
