Yes I know the cause of this incident. I can say that the aircraft had FUEL onboard however at this time I'm not able to say what the cause was and I do know.
Now as for Clinton like I've said before how many engines have you ever serviced and how many cylinders have your ever removed. And what happens to the exhaust gas when you lean it out.
So far this year one engine removed all but destroyed by running lop and 8 cylinder changes. But then maybe we should go against the ads and manufacturers recommended test process as creamie and Jaba say they wrong and they know best.
