At approximately 0711 c.s.t. on December 27, 1968, Ozark Air Lines Flight 982, a Douglas DC-9, crashed while taking off from the Sioux City Airport, Sioux City, Iowa. There were no fatalities. Among the 64 passengers and four crewmembers, 10 passengers were hospitalized with minor injuries and three crewmembers received serious injuries. The aircraft was destroyed in the crash. There was no fire. The Safety Board determines that the probable cause of this accident was a stall near the upper limits of ground effect, with subsequent loss of control as a result of the aerodynamic and weight penalties of airfoil icing. The flightcrew failed to have the airfoil ice removed prior to the attempted takeoff from Sioux City. The Board also finds that the crew selected an improper takeoff thrust for the existing gross weight condition of the aircraft. (Author)
