Circumstances:

It partially disintegrated during the descent and eventually crashed in a pasture. The aircraft was totally destroyed and all seven occupants were killed.
Probable cause:
Failure of the artificial horizon for unknown reasons. The airplane later disintegrated in the air due to aerodynamic forces that exceeded its design and certification.
