Probable cause
The in-flight failure of the left wing lower forward attach point under normal loading conditions due to corrosion and fatigue cracking in the center section hinge brackets. Contributing to the accident was the operator's inadequate maintenance and overweight operation of the airplane, and the manufacturer's inadequate guidance to detect and prevent corrosion and fatigue cracking.
