Beschrijving:
Ryan Flight 590 landed at Cleveland at 23:44 and taxied to the mail ramp. Snow (dry and blowing) fell throughout the 35 minutes that the DC-9 was on the ground. The de-icing service was not requested during this period. Clearance to taxi to runway 23 was received at 00:09. Takeoff clearance was given at 00:18.
The aircraft stalled during takeoff 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:

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."
