Question: 1 / 400

If a fire starts in the induction system during the engine starting procedure, what should the operator do?

Turn off the fuel pump switches.

Continue cranking the engine.

During the engine starting procedure, if a fire starts in the induction system, it is important for the operator to continue cranking the engine. Turning off the fuel pump switches may cut off the flow of fuel, but it could also stop the flow of air and potentially make the fire worse. Turning off the magneto switches may stop the ignition process, but the engine will continue to crank, potentially causing more sparks and making the fire bigger. Using a fire extinguisher immediately may be tempting, but the force of the extinguisher's discharge could spread the fire or cause damage to the engine. Therefore, the best course of action is to continue cranking the engine and allowing the starting system to pull air through and suppress the fire.
