Low oil pressure may be indicative of an imminent engine failure.
See OIL PRESS Warning
A damaged (out-of-balance) propeller may cause extremely rough
operation. If an out-of-balance propeller is suspected, immedi-
ately shut down engine and perform
If the power loss is due to a fuel leak in the injector system, fuel
sprayed over the engine may be cooled by the slipstream airflow
which may prevent a fire at altitude. However, as the Power Lever
is reduced during descent and approach to landing the cooling air
may not be sufficient to prevent an engine fire.
Selecting BOOST may clear the problem if vapor in the injection
lines is the problem or if the engine-driven fuel pump has partially
failed. The electric fuel pump will not provide sufficient fuel pres-
sure to supply the engine if the engine-driven fuel pump
Selecting the opposite fuel tank may resolve the problem if fuel
starvation or contamination in one tank was the problem.
Cycling the ignition switch momentarily from BOTH to L and
then to R may help identify the problem. An obvious power loss in
single ignition operation indicates magneto or spark plug trouble.
Lean the mixture to the recommended cruise setting. If engine
does not smooth out in several minutes, try a richer mixture
setting. Return ignition switch to the BOTH position unless
extreme roughness dictates the use of a single magneto.
If a partial engine failure permits level flight, land at a suitable
airfield as soon as conditions permit. If conditions do not permit
safe level flight, use partial power as necessary to set up a forced
landing pattern over a suitable landing field. Always be prepared
for a complete engine failure and consider CAPS deployment if a
suitable landing site is not available. Refer to Section 10,
