It doesn't take magic when you get in over your head, fly into known icing in a plane that can't handle it, and you become disoriented.
NTSB:
The pilot’s inappropriate control inputs as a result of spatial disorientation, which led to an aerodynamic stall and loss of control. Contributing to the accident were the pilot's decision to conduct flight into known icing conditions, ice accumulation that reduced the airplane's aerodynamic performance, and the pilot's failure to initially intercept and establish the airplane on the proper approach course.
