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:
1. Bat-Alt Master Switches........................................ OFF, AS REQ'D
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
4. Fire Extinguisher ............................................................ ACTIVATE
Halon gas used in the fire extinguisher can be toxic, especially
in a closed area. After extinguishing fire, ventilate cabin by
opening air vents and unlatching door (if required).
If airflow is not sufficient to clear smoke or fumes from cabin:
5. Cabin Doors .......................................................PARTIALLY OPEN
Airspeed may need to be reduced to partially open door in flight.
6. When fire extinguished, Air Vents ................... OPEN, FULL COLD
7. Avionics Power Switch ............................................................. OFF
8. All other switches ..................................................................... OFF
9. Land as soon as possible.
If setting master switches off eliminated source of fire or fumes and
airplane is in night, weather, or IFR conditions:
If airplane is in day VFR conditions and turning off the master
switches eliminated the fire situation, leave the master
