Plane into building

Pretty short runway for that plane.

Does anyone have the takeoff performance tables from the POH for that aircraft?

This doc puts it only at 3190:

Sounds like they were definitely pushing it.

Just a 600’ DA at 4AM based on nearby METAR.

I don’t care what the numbers say. I have thousands of hours in the airplane, and 3600 feet does not have “reasonable margin” on a summer day.

That’s my opinion, regardless of book numbers.

Of course I have no time in jets but here is how I would figure it in my Cardinal.

What is the book takeoff distance - in this case perhaps 3190. add 50% is 4785. So we need to be careful here and figure it by the book.

Koch chart says maybe 2% more needed for the DA. So 3253'. Of course, I don't know if the starting number here is over a 50' obstacle -- probably is.

So I would get the POH and compute the ground run. Then figure out what the abort point is going to be. I mean the landing distance is listed as 3180, probably also over a 50' obstacle. It almost seems like you really can't safely take off from that field in this plane.

On Reddit someone said it was from an engine out. So either it was dual engine out or some failure of takeoff distance, single engine procedures, etc. All speculation and no facts here.

Certainly two turbine engines out from mechanical failure seems exceedingly unlikely. Operator error causing two engines out - maybe.

Does that type of plane have a CDR?
