Didn't look at the picture since gored animals aren't really my thing...

But 2 years ago a corperate jet taking off at an airport in Oregon hit an Elk at rotation.  It ended up doing a belly landing off the end of the runway because of the damage.  Everyone was OK except the elk and the plane.  I guess that one comes out a draw.

I didn't know deer could fly...other than Reindeer. I hope that wasn't Donner.

Unfortunately, IIRC they are going to have to rebuild the engine.

I am not too sure about that, if memory serves me, the King Air 200 prop is driven by a free turbine and unless there was an EGT overtemp, it shouldnt have effected the engine at all.  Would have to check the maintenance manual on that.

A prop driven by a free turbine has no direct mechanical connection to the engine, rather the prop is driven by a turbine disc that has air directed onto it.   That is how the King Air 200 I am familiar with operated.

Not an A&P or even remotely close :)  I just remember reading a generic text that prop strike = engine rebuild but that was in the case of the ground.   I know it's not necessary with a bird for a rebuild but deer, beats the hell out of me...

Yeah, that is the case with the majority of prop driven aircraft, and includes alot of Turboprops too, like the Allison used on alot of aircraft, and it is a guarantee with any pistion engine.  Big issue is crankshaft on piston.

But the Pratt and Whitney PT6 on the King Air uses the Free Turbine I mentioned.  You can actually hold the prop still while the engine is started.  I don't know at what point the forces would be too great, but I expect it would eventually be too much to hold.

If you are around a Turboprop with PT6, when they start they often leave the prop in a pitch I believe to be at or near feather, then, they prop is turning much slower and quieter than normal, and you can easily hear the differance when the pilot brings the prop out of that range and into normal pitch.
