At least it looks like the model is saved, must be something wrong with fuel metering?

LMFAO!!!! I'm just sayin, if you had that much trouble getting one engine to run while the other one was left idleing don't you think it would have been wise to SHUT IT DOWN. Take it back to the pits and check it out or even do a full throttle run up before you take off. This could have been avoided. Also what the hell was the lighter going to do, make it magically fire up.

A fuel cut off valve would have been handy. The turbines kept pumpimg fuel in even though the turbines were probably no longer running. Especially after several shots from the extinguisher, she kept reigniting. Bummer.

this video was posted a few weeks ago, the owner of the jet got his panties all in a bunch about some of the comments made but his words were the ECU's both stuck with fuel pumps in full on..........both turbines were toast.

Looks like he did an excellent job of landing with his prize on fire. Dont know if i could have remained steady enough.

I would have been tunning to the extinguisher before baseleg

Just wondering if all ecu's would be so vulnerable? With what i run, i just dont see it happening. The pump would have been shut off automatically. Any insight on brand, and why the pumps kept the fuel running?

I think some ECU like the (Older RAM ECU) will see high temp as engine still running and will increase pump voltage to keep the RPM from dropping .

My Opinion

I saw the same thing on a old Jet Cat ECU on a P-80, the guy had a flame out and when we went over to pick up the plane fuel was coming out the back of the turbine full bore.... he was lucky the flame was out!

Yep this also happen to a friend of mine. After a flame he manage to do a perfect bellyland. The jet was out in the field without any damage, But halfway to the plane we saw black smoke. I ran to the plane and he ran back for the extinguisher. Pump was still running but it was too late with the extinguisher.
