Machaca, thank you for he pictures.
I notice that the Propeller is full feathered.
Propeller at the PC12 feathers if you lose oilpressure, or if the engine has been cut with the condition lever. Not if the engine quits by it self or lack of fuel during normal flight. Windmilling core engine gives enough oilpressure to keep the Propeller in fine coarse.
In a spinning aircraft the forward speed isnīt enough to keep the engine windmilling, so the propeller might feather then.
Both wingtanks are ruptured.
Did the left wintip come of during flight or on the ground ?
Ist that oil on the left windscreen or is it smoke from the post impact fire ?
