Probable cause
The pilot's failure to maintain airplane control while operating in instrument flight rules (IFR) conditions, which was due to spatial disorientation resulting from erroneous heading and bank angle information shown on the primary flight display. Contributing to the accident were the pilot's impairment due to diphenhydramine and his improper decision to operate in IFR conditions with the airplane over gross weight and at an aft center of gravity.
