complete engine failure and consider CAPS deployment if a suitable
landing site is not available. Refer to Section 10, Safety Information,
for CAPS deployment scenarios and landing considerations.
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.
• WARNING •
If there is a strong smell of fuel in the cockpit, divert to the
nearest suitable landing field. Fly a forced landing pattern and
shut down the engine fuel supply once a safe landing is
assured.
The following procedure provides guidance to isolate and correct
some of the conditions contributing to a rough running engine or a
partial power loss:

1. Fuel Pump ......................................................................... BOOST
Selecting BOOST on 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 pressure to supply the engine if the engine-driven fuel pump
completely fails.
2. Fuel Selector........................................................ SWITCH TANKS
Selecting the opposite fuel tank may resolve the problem if fuel
starvation or contamination in one tank was the problem.
3. Mixture ............................. CHECK appropriate for flight conditions
4. Power Lever .......................................................................SWEEP
Sweep the Power Lever through range as required to obtain
smooth operation and required power.
5. Alternate Induction Air ...............................................................ON
A gradual loss of manifold pressure and eventual engine
roughness may result from the formation of intake ice. Opening
the alternate engine air will provide air for engine operation if the
normal source is blocked or the air filter is iced over.
6. Ignition Switch.......................................................BOTH, L, then R
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.
7. Land as soon as practical.

Propeller System Emergencies
Propeller Governor Failure
If the RPM does not respond to power lever movement or overspeeds,
the most likely cause is a faulty governor or an oil system malfunction.
If moving the power lever is difficult or rough, suspect a power lever
linkage failure and perform the Power Lever Linkage Failure checklist.
Propeller RPM will not increase:
1. Oil Pressure ....................................................................... CHECK
2. Land as soon as practical.
Propeller overspeeds or will not decrease:
1. Power Lever .................................ADJUST (to keep RPM in limits)
2. Airspeed........................................................ REDUCE to 90 KIAS
3. Land as soon as practical.

Fuel System Emergencies
High Fuel Flow
FUEL FLOW Warning
Fuel flow greater than 30 GPH.
On-Ground
1. Correct prior to flight.
In-Flight
1. Mixture ..............................................................................ADJUST
Adjust engine operation to correct condition. Check engine
instruments to verify HIGH FLOW Warning is not erroneous, i.e.
abnormal engine temperatures or engine roughness after mixture
adjustment.
If FUEL FLOW Warning does not extinguish:
2. Land as soon as practical.
Low Fuel Quantity
FUEL QTY Warning
Fuel Totalizer quantity less than or equal to 9 gallons.
1. Fuel Quantity Gages.......................................................... CHECK
If fuel quantity indicates less than or equal to 9 gallons:
a. If On-Ground ..............................REFUEL PRIOR TO FLIGHT
b. If In-Flight ........................... LAND AS SOON AS PRACTICAL
If fuel quantity indicates more than 9 gallons:
