While holding, the plane encountered freezing rain]] — a dangerous icing condition where supercooled droplets rapidly cause intense ice buildup.
At 15.57:38, as the airplane rolled back to the left through 59 degrees Those tests limited the size of the droplets to 40 micrometres, near the maximum limit of the FAA design certification rules for Transport Category aircraft (Part 25, Appendix C), still in effect at that time of the Roselawn crash. At 15.57:33, as the airplane
because of deteriorating weather conditions at destination Chicago-O'Hare, While the ATR 42 and ATR 72 aircraft are now compliant with all icing condition requirements imposed by those 18 ADs, the de-icing boots still only reach back to 12.5% of the chord.
