As the landing gear began to retract, the aircraft rolled abruptly and violently to the right to an angle of bank estimated by the flight crew to have reached 900. The captain applied additional power and left rudder in an attempt to level the wings. When no immediate response was noted, he then applied left aileron. With the application of left aileron, the right wing came up; however, the roll continued to the left until the left wing contacted the runway. At this point, the captain discontinued the takeoff.

No difficulty was experienced as the flight proceeded to Omaha at 4,000 feet in accordance with an instrument flight plan. A normal landing was made on Runway 11 about 1,000 feet from its approach end, but near the completion of the landing roll the aircraft ran off the right side of the runway, passing over one of the high intensity runway lights. Captain Graham reported this to one of the ground crew at Omaha, and both the aircraft and light were inspected for damage. None was found and the aircraft was prepared for departure to Sioux City. At 0841 the flight took off for Sioux City on an instrument flight plan with Omaha as the alternate airport. There were 21 passengers, 920 pounds of cargo, and 1,500 pounds of fuel, which resulted in a take-off weight of 24,630 pounds.

Shortly thereafter, it was sighted approximately over the intersection of Runways 4/22 and 17/35 on an east-southeast heading. A left climbing turned to the north was then made and the pilot was advised that he was cleared to land on either Runway 17 or Runway 13. The pilot was also advised by the tower that there would be a 90-degree cross-wind if he elected to land on Runway 17. All transmissions to the flight were acknowledged The aircraft was not further observed, and crashed about 600 feet north and west of the approach end of Runway 17. Fire developed immediately.
