He had climbed and positioned himself between the mast and overhead cage (18 inches in width) to place a chain through the rear of the mast. His foot struck the controls and caused the mast to tilt back and pin him between the mast and cage. He suffered a severe blunt injury to his abdomen. Accident-related violations: T8CCR 342(a), regulatory; T8CCR 3664(a), general; and T8CCR 3203(a)(3), serious.
