Looking at Aviation Safety Network the DC9/MD80 series have had three previous accidents involving loss of power to both engines...[list=1][*]1977 - DC9 - "entered severe thunderstorms between FL170 and FL140 over Rome, GA. Both engines failed and couldn't be restarted."[*]1985 - DC9 - "Just after lift-off, the DC-9 rolled left and both no. 1 and 2 engine compressors stalled."[*]1991 - MD81 - "the aircraft took off with clear ice on the wings. In connection with lift-off, the clear ice loosened and was ingested by the engines. The ice caused damage to the engine fan stages, which led to engine surges. The surges destroyed the engines. The plane then struck sloping ground tail-first and slid along the ground for 110m. The fuselage was broken into three pieces, but there was no fire. Crashed with approximatly 4000 kg of fuel onboard."[/list=1]

Other icing accidents involving DC9's
[list=1][*]DC9 - 1968 - "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."[*]DC9 - 1991 - "The aircraft stalled during take-off and rolled 90 at 50-100 feet. The airplane then suffered compressor stalls, the left wing contacted the runway and the aircraft cart wheeled. The DC-9 came to rest inverted 6500 feet from the threshold.
PROBABLE CAUSE: "The failure of the flight crew to detect and remove ice contamination on the airplane's wings, which was largely a result of a lack of appropriate response by the Federal Aviation Administration, Douglas Aircraft Company, and Ryan International Airlines to the known effect that a minute amount of contamination has on the stall characteristics of the DC-9 series 10 airplane. The ice contamination led to wing stall and loss of control during the attempted takeoff." [/list=1]
