The Engine Fire procedure for my plane requires closing the fuel valve and going to full throttle. Anyone know how long it takes for a 914 to quit with that technique?

Thanks,

 

Mike

    Could probably test that on the ground. Set a cruise RPM, close the fuel valve, go full throttle…..

    The engine will quit soon as the carb fuel bowls go dry and can no longer deliver fuel.
    This might take a dozen seconds or so.
    As Byron suggested, it would be easy to test on the ground.

    Please, Lets us know what you find.

    I should have said in my original post that the engine is down with a mechanical issue, so I can't test it at this time.

    Since I can't fly, I was reviewing the AFM. The procedures for engine fire inflight and on the ground are the same - shut off the fuel and open the throttle.  Unless you're wearing a parachute, you're stuck in the plane in the air, but I was thinking that if it takes more than a few seconds for the engine to shut down, it would be better to get out of the plane sooner on the ground.

    At idle on a 912UL it can take over 60s to drain the carbs sufficiently to stop the engine. I haven't tried it at higher RPM but I suspect that it would be at least 10s or more. I would be interested to know the answer to this question.

    For fast engine "kill" - shut of fuel supply and apply full choke
