I seem to remember the max EGT 1080 degrees for 2 seconds on start, or was it less? :ooh:
I still have an occasional dream about not paying attention and over-temping a turbine engine.

I understand where you coming from as a pilot but your talking about a individual stealing an airplane and threatening to level a Walmart. I'm guessing the last thing he was worried about was overheating the engines

No mystery. Guy had student ticket but not current however flew on occasion with local pilots/CFIs to include on this aircraft. High time local pilot talked him down into field. Young man has some issues to deal with and this episode caught all who knew him way off guard. Glad it worked out in the end. Don't think it was too outside his skill set to get it started and take off.

My 18 yr old starts engines on various jets daily on his flight sim, to include mine. The sim ensures you do it correctly or FADEC aborts the start, just like the real aircraft. Perhaps this young man had opportunity to learn to start the PT6 the same way.

Yes of course..
Cooking a hot section was the least of his worries.
My comment was rather that any monkey could get an engine started but it may be useless in the near future.

I'm curious as to how they are going to recover this aircraft from the field... my guess is they are not going to fly it out!

Hard to tell if it was a old 90 or 100. Didn’t the old 90’s have glow plugs

It's a 1987 C90A...

Of course you do pay attention to the ITT limit on start but how often does it really move even close to that? I must have watched almost several thousand PT-6 start sequences and maybe had one or two go hot and require a fuel shut-off outside of a Sim. Chances are probably much higher if you don't use a GPU but as said above, that guy probably would not have cared and a momentary exceedance of even a 100 degrees probably won't kill the engine.

Thinking about that: are there any non-EFIS transport airplanes that use Fahrenheit for ITT? Do US based planes use Fahrenheit for oil temperature?

In this case, depends on the insurance company. My guess given the age/type of aircraft the engines will be pulled then the wings and tail cut off and moved by easiest means to where it can be trailered. There are other options especially if someone has bought any salvage right.

Thats nonsense.
They wouldn’t even be in the air after 300 seconds.

While I agree that 300 sec is probably not realistic in this scenario, there is a QRA readiness state of 5 min.
During times of tension, this state may be applied and in that case the scrambled Quick Reaction Alert aircraft must be in the air within 300 secs.

Not generally an easy transition even if he was a licensed pilot with C172 time.

Being a licensed 172 pilot who doesn't flight sim, I'd probably be caught and arrested before I found the right section in the flight manual pertaining to engine start procedures. :}

Drone Video of Crash Site
 
From this video, the plane had its gear down and was doing apparently quite well until it hit the ditch. The landing gear appears to have snapped off at the ditch. This is a 1987 build... I strongly suspect it's a total loss.
