I heard it was in-flight, possibly during a go-around, not during the start.
Wow would have to be the over torque of the century

Nice theory Checkboard.... but really how much time would you save?
Seeing as though it is possible to start two PT6s on a KingAir in two minutes without rushing, you'll save more time by chosing an optimum level!
If the reported 1000 for 10 seconds occurred on both, my money is on something like takeoff, a go-around or getting way too enthusiastic with the reverse. It's just not 'easily' possible any other way.
It does beg the question- how did it get that far gone in the first place?
I've been a little ham-fisted once or twice and seen the ITT just about poke redline, but still FAR below any transient or sustained limiting temperature.
Rich-Fine-Green, if somebody left the bungs in they havn't done any walkaround, let alone a proper one- and they ballsed up big time. But doubtful it would cause two cooked engines.
But then again, you'd be amazed at some people I'm sure. After frying one on start, they probably would think the other will be ok after a recharged battery
*not saying whether or not that the cooked engines in this case were a result of a start, but its just bloody unlikely!*
Electronic trend monitoring helps sort these capers out!

It's a Proline 21 equipped C90 isn't it?
If so, I'm assuming the trend monitoring is the same as the B200's. If an overtemp had occurred, once the trend monitoring picks it up it sends the data via satellite to the US which then sends an email to the appropriate person at the operator. Happens so quickly, the operator would have known about it before the aircraft got on the ground.
How you cook 2 engines though, is beyond me. The only way would be a go-around or take off that got seriously f**ked up!
And people think turbines are fool proof..... Nearly, just so long as you don't have fool's not watching and thinking about what they're doing,

Isn't the Proline 21 trend data download an option rather than standard issue
I doubt the C90 had it but I could be wrong

Not sure megle, I don't buy the things, I only fly them. All the one's I've flown work like that.
