2. Land as soon as possible.
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 80 KIAS
3. Land as soon as practical.

Smoke and Fume Elimination
If smoke and/or fumes are detected in the cabin, check the engine
parameters for any sign of malfunction. If a fuel leak has occurred,
actuation of electrical components may cause a fire. If there is a strong
smell of fuel in the cockpit, divert to the nearest suitable landing field.
Perform a Forced Landing pattern and shut down the fuel supply to the
engine once a safe landing is assured.

2. Navigation Light Switch............................................................OFF
3. Landing Light ...........................................................................OFF
4. Strobe Light Switch..................................................................OFF
5. If possible, side slip to keep flames away from fuel tank and cabin.
• Note •
Putting the airplane into a dive may blow out the fire. Do not
exceed VNE during the dive.
6. Land as soon as possible.
Cabin Fire In Flight
If the cause of the fire is readily apparent and accessible, use the fire
extinguisher to extinguish flames and land as soon as possible.
Opening the vents or doors may feed the fire, but to avoid
incapacitating the crew from smoke inhalation, it may be necessary to
rid cabin of smoke or fire extinguishant. If the cause of fire is not
readily apparent, is electrical, or is not readily accessible, proceed as
follows:
• WARNING •
Serials 1337 and subsequent: If the airplane is in IMC
conditions, turn ALT 1, ALT 2, and BAT 1 switches OFF. Power
from battery 2 will keep the Primary Flight Display operational
for approximately 30 minutes.
1. Bat-Alt Master Switches........................................ OFF, AS REQ’D
• Note •
With Bat-Alt Master Switches OFF, engine will continue to run.
However, no electrical power will be available.
2. Heater ......................................................................................OFF
3. Air Vents........................................................................... CLOSED
