NTSB said 1/2 to 3/4.1/2 a mile from the impact site isn't that far. That's not a breakup at altitude. That's something coming off on its way down.
I definitely didn't expect that. I've been in the PC12 in extremely rough weather and had no problems nor have I heard of any inflight breakups in it except for the one that tried to fly through a thunderstorm... that's shocking to me. That thing is built hella stout.“How do we know if the airplane broke up in flight? We found parts of the airplane one-half to three-quarters of a mile away” from the crash scene, NTSB Vice Chair Bruce Landsberg said at a news briefing in Carson City.
NTSB says medical plane apparently broke apart before crash
The National Transportation Safety Board has sent in a seven-member team of investigators to the site of Friday night’s crash near Stagecoach.www.newsnationnow.com
Based on your recent guessing and my recent guessing, I'd be wise to stay the course.

Edit:
Ah, makes sense if it came apart on the way down...
yeah, I did some "back of the envelope math" and come up with only 2gs at the start of the spiral dive, and maybe up to 3.5g just in terms of centrepetal acceleration towards the end... but yeah, he stays below barberpoll the whole flight. 236KIAS or .48M in the PC12 if memory servesUm... ok?
Yeah, the one that broke up was 100+kts above redline in a dive and yanked back on the yoke.
This one might not be similar.
IF the speeds are correct, he was still below redline.

Just dropping this here, might do more good than our collective speculations

Might have been my point;
Were all people up there, and often we lose sight of it when someone goes down. Seeking answers is important, but that can wait imho; especially to the pros. Its who they left waiting at the airport that should matter now…
while true, seeking answers does have a concurrent importance (which the pros are doing), in accidents where potential exists for a possible fleetwide issue that may need an immediate address. Such as the Blackhawk spiraling down to earth, and then I look at my own flightline and see that I jflew the #5 UH-60 Blackhawk ever built…..a hard-ridden 1977 model…..just the other day.
you are indeed a pro though…fleet-wide issues aren't exactly something id expect to be anecdotal or speculative knowledge, though the ATR crash a bit back does ring a bell. Id imagine the people in the “know” would have already been contacted.

Having come from the air ambo world with a wife and boys, I feel so much for that family. It really is a terrible tragedy.Really hits home when you see the wife and little girls.
Oof level: beyond the upper end of the measured range.Maybe he hit a balloon
Wouldn't be the first in-flight breakup of a PC-12...
Hope some answers are gained.
I don’t think there are any - there are a couple examples of trying to fly the things through thunderstorms, but no wing failure accidents out of the blue that I’m aware of.PC-12 are built like a brick poop house. I used to fly a privately owned one. It changed hands and wound up in Florida. It broke up in mid air but the part 91 owner operator flew it directly into a massive thunderstorm. Which I think would probably happen to most airplanes if you flew them right into a thunderstorm. The last part of the N number was PA. I can’t remember the whole N number though.
What other examples are there of a PC-12 breaking up in-flight?

@inigo88 - you did structural work, are the g-liftings magnified or are airplanes just not designed for twisting loads (a la rolling g) - I guess I mean to say is it the case that the “asymmetrical applications magnify loading” or do the design load limits drop with asymmetrical applications?The G loadings on the airframe will be magnified if non-symmetrical vs symmetrical application, which in a spiral will definitely have some of the former.
