7. FIRE
The safety of the helicopter occupants is the primary consideration when a fire
occurs. Therefore, if airborne, it is imperative that the pilot maintain control of
the aircraft and land immediately. If the fire occurs on the ground or upon
landing from an inflight fire, it is essential that the engine be shut down, crew
and passengers evacuated and fire fighting begun immediately. If the situation
permits, a ‘‘MAYDAY’’ radio call should be made before electrical power is OFF
to expedite assistance from fire fighting and rescue personnel.
Indications:
The sound of electrical arcing, the smell of burning insulation, or the
sighting of smoke and/or flame are all possible indicators of an on board
fire. Also, the pilot may be notified of an on board fire by personnel
outside the aircraft via visual or audio communication methods.
At unprepared landing sites, dried grass or brush may catch fire
