3-7
17. A rough running engine and / or a partial loss of power can be caused by a number of
factors, including but not limited to:
a. incorrect mixture setting;
b. engine driven fuel pump failure (refer to Low Fuel Pressure, Figure 3-6);
d. icing of the air induction system;
h. loss of lubrication (refer to Low Oil Pressure, Figure 3-5); or
i. major mechanical failure.
18. The actions to be taken in response to a rough running engine should consider:
a. while attempting to identify and correct the problem, it may be appropriate to
manoeuvre the aircraft so as to optimize the position for a forced landing should
the situation deteriorate;
b. immediate actions should be taken appropriate to the symptoms indicated in
Figure 3-7 below; and
c. if the problem cannot be identified and corrected, action should be taken to
conduct a precautionary landing as soon as possible.
