Section 4
Electrical Fire (Cabin Fire In Flight)
An electrical fire or cabin fire in flight is an emergency situation
requiring immediate pilot action. The pilot must turn off power sources
and electrical equipment to eliminate an electrical fire. In VFR
conditions, it is recommended to turn off both batteries and
alternators. Reference the magnetic compass, backup airspeed
indicator, backup altimeter, and outside visual reference for aircraft
control.
In IMC conditions, or conditions that require flight by reference to
instruments, turn off all switches except BATT 2 to preserve power to
the primary flight display and backup attitude indicator. There is a high
probability that the source of fire will be eliminated. Turn off BATT 2 if
the fire continues to burn. Activate CAPS if controlled flight can not be
maintained.
Procedure
1. Oxygen System (if applicable) .................................................OFF
Turn off the oxygen system, if applicable, to reduce the chance of
a severe fire in the cabin.
2. Bat-Alt Master Switches ........................................ OFF, AS REQ’D
In VFR, turn off all battery and alternator switches. When flight by
reference to instruments is required, leave BATT 2 ON.
3. Fire Extinguisher ............................................................ ACTIVATE
