Narrative:Weather at Sioux City was poor: 800 feet overcast, 3 miles visibility in fog and light freezing drizzle.
Flight 982 took off from runway 35 and, upon gear retraction, rolled violently 90° to the right. The roll was counteracted, but the left wing struck the runway. The DC-9 crashed and came to rest in a grove of trees, 1181 feet past the runway end.
PROBABLE CAUSE: "A stall near the upper limits of ground effect, with subsequent loss of control as a result of aerodynamic and weight penalties of airfoil icing. The flight crew failed to have the airfoil ice removed prior to the attempted take-off from Sioux City. The Board also finds that the crew selected an improper takeoff thrust for the existing gross weight condition of the aircraft."
