Electrical fire in flight
An electrical fire is often characterized by white smoke and an acrid
smell.
1. Auxiliary fuel pump
- on (see WARNING below).
2. Master switch
- off (see NOTE below).
3. Cabin heat
- close.
4. Use the fire extinguisher (if possible).
5. Ventilate cabin if required / applicable (open air vents on instrument
panel).
6. If fire is extinguished consider executing a precautionary landing /
land as soon as practical.
7. If fire does not extinguish land immediately.
NOTE:
If the location of the electrical fire can be determined and
electrical power can be removed from that system / location by
isolating / switching the system off, do so. This may alleviate the need
to switch off the master switch.
The EFIS and associated equipment (iBox, RDAC etc.) can still be
powered (to provide engine monitoring) from the EFIS back-up battery
circuit when the master switch is off, provided that the EFIS system is
not the location / source of the electrical fire.
WARNING
If the master switch is switched off without the auxiliary fuel pump
being ON both fuel pumps will be inoperative!
If the alternator / charge system is failed and the master switch is
switched OFF (i.e. disconnecting the remaining power source
(main battery) from main bus) both fuel pumps will be inoperative
(and the engine will cease running due to fuel starvation)!
