Factual Report: UND icing research flight suffered dual flameout
Cessna 550 Citation II, Ft.

Cessna 550 Citation II, Ft. Yukon, Alaska, Sept. 30, 2005–The captain, copilot and two research scientists were not seriously injured when Citation N77ND made an off-airport, gear-up emergency landing after both engines quit simultaneously. The University of North Dakota flight was doing icing research in IFR conditions when the accident occurred.

The captain told the NTSB that about seven-eighths of an inch of ice had accumulated on the wing leading-edge surfaces. He cycled the de-ice boots, then heard a loud “bang” at the rear of the airplane and both engines lost power. Descending, he tried to restart the engines. At about 3,000 feet above the ground, he abandoned restart attempts and concentrated on landing. The airplane’s wings, fuselage and empennage were damaged.
