Probable cause
The failure of the electrical system due to an alternator failure during flight in instrument meteorological conditions, and the pilot’s inadequate preflight inspection and failure to use the approved checklist for the dual alternator system. Contributing to the accident was the inadequate maintenance because the alternator restart battery pack was not replaced annually, as required by the airplane service manual.
