Cessna 182 - Engine Fire on Start; on Ground

Engine Fire on Start / on Ground
22. The most likely cause of a fire on start is over-priming with subsequent backfiring igniting
the excess fuel in the air induction system. The best way of containing such a fire is to continue
cranking the engine so as to suck the flames and accumulated fuel into the engine. If at any
time on the ground an engine fire is evident from the cockpit, the aircraft should be abandoned
as soon as possible.
